20 Best Micro Sd Card For Roku Ultra (2023 Updated)

I purchased this to provide an alternative boot card for my Raspberry Pi 3 Model B. The Raspberry Pi 3 kit I purchased came with a single 16 GB microSD card and I wanted another that was larger since this is the disk for a Pi.

I ran down to a local store and bought a Sunpak 72-in-1 USB card reader which allowed me to do the setup with my Windows 10 desktop PC. I did use the SD adapter and the standard size SD port on the reader.

Windows 10 was super easy to download the NOOBS Lite loader, extract the files from the zip downloaded, and put the files onto the microSD card. While I used the “partition” command of Windows 10 to look at the microSD card format, I did not have to make any actual changes.

All I had to do was to copy the files extracted from the NOOBS download to the microSD card. I swapped out the kit microSD card for this one in the Raspberry Pi and plugged in the power adapter. The Pi came up, did the NOOBS initialization, I set up the WiFi settings so the NOOBS Lite could see the internet, and did an install of Windows 10 IoT which took a while but went fine.

A test program with Visual Studio 2017 Community Edition checked out so it looks like it is all golden.

If a single mum like me can do it, then so can you 😉 love this little gadget sooo much, I’m telling everyone about it, just download the app, plug it in, connect and off you go I haven’t quite explored all the tricks it has yet, but just a bit of proof, had my local garage try to prove me wrong after I told them there was only one fault left on my car, he asked if he could put his 2.

5k snap-on kit on, of course I said yes sure, and guess what?? Same result!! Maybe a bit more detailed, but came down to the same conclusion, replace my lambda sensor! Lol he was very impressed with my little Bluetooth scanner, it’s helped me enormous finding faults instantly instead of pouring money into parts not needed trying to hunt down any problems with your car, a very very happy customer here! Highly recommended, even if you’re not doing your own mechanics as there are many other uses for it, like help you save on your fuel consumption, really worth getting, it will pay you back tenfold.

Was having issues with GoPro acting up while recording 4K. Would shut off for no reason. Did some research and other were having similar issues. This card seemed to have one of the fasted read & write speeds, and was very reasonable priced.

Now everything works as it should.

These are slightly more expensive than the very cheapest but well worth the extra couple bucks. I use drones and ip cameras, I haven’t had even 1 of these fail me. the cheaper brands fail within a year or so.

They come in all speeds and number of gigs so it’s easy to find one that meets your particular requirements.

I’m very pleased with my product. It was at good price range. Delivered even a day early. Nicely packaged. With packing list for return if desired. Thank you very much walmart

easy to transfer from micro to hard drive. glad I bought them

TEST YOUR CARD BEFORE REVIEWING IT! You can’t judge a card based on its label and the fact that it can store SOME data. Cards are sold every day with a falsified format that make them appear to have a lot more storage capacity than they actually have.

I bought 3 of these 256 GB “SanDisk” cards at the same time. I opened one package and tested it with a well-known and trusted tool called “f3”. You run f3write to fill the card with data, and f3read to check that the data were properly written.

The first card failed in a way that suggests this is a 32 GB card that has been (intentionally?) malformatted as 256 GB. I opened the 2nd package and tested the card the same way, with the same result.

I then took a 256 GB card I had previously purchased elsewhere, and ran the same test on it, using the same tools and the same computer — it checked out perfectly. The most charitable thing I can say is that it might be remotely possible this seller doesn’t know they are buying from a “shady” supplier.

This is not a SanDisk problem. I have perfectly good cards from SanDisk. These are probably not SanDisk cards, or they may be SanDisk cards that have been relabeled and repackaged.

I bought two of these. I actually use these for computer file storage because they are so compact and are very covert for portable applications. If you think about it, 5 of these stacked up is the equivalent of 5TB but in under the size of a few coins.

It is amazing how far technology has come. The quality is outstanding as usual -no corrupted files, transfers quickly, gets heated when writing very large quantities for a bit of time, but I rarely do that so not an issue.

They do seem to keep cool enough to maintain the higher speed so that is good. Remember, to get the best speeds, you need the right readers, usb cables, and ports. This all works together. I have used the 256gb, 512gb, and now 1tb sizes of these and so to extrapolate to past ones I have purchased, again, never had issues.

When these are on sale, the price is fair. I use my old ones in cameras now and they record 4k video with ease. Can’t wait for 2TB haha, or at least 2TB in an SD card since technically it would fit.

I am not impressed as the advertised read speeds are not achieved in real world scenarios. I tried it on Windows 11 with a USB 3. 0 microSD Card reader and on two android devices, an older: HTC U11 and a newer: Xiaomi Redmi Note 10 Pro.

The benchmarking results do not even cross 100 MBps. H2testw gave poor results, CrystalMark results were better. CrystalMark Windows 11 Ryzen 7 with USB3. 1 Port: Read 95. 75 MBps. Write: 88. 63 MBps.

Android Redmi Note 10 Pro: Read 84. 15 MBps. Write 48. 16 MBps. Android HTC U11: Read 83. 55 MBps. Write 41. 47 MBps. Sandisk advertises it to reach 170 MBps using their own USB 3. 0 microSD card reader.

Unfortunately, I don’t have said device, to perform the test. I’ll be using this card in my DJI Mavic Air 1, so shouldn’t be a problem as this card fulfils Mavic Air’s 4K requirements.

TraduireAfficher dans la langue originaleI got one of these, and in the beginning it seemed to work. Speed was decent. But after a few hours, my tablet said “no card inserted”. I had to remove/reinsert for it to see it again, and that worked for a few more hours.

then it repeated. and again. and again. Clearly a defective card — but that happens from time to time. I called BestBuy to get a new one, but they won’t exchange an SD card if the package is open, even if defective.

How am I supposed to know it’s defective without opening it? They said call the manufacturer. So I did, and the manufacturer wants me to pay for shipping to return it, which costs about as much as the card itself, and may not result in me getting something that works.

Good money after bad, as the saying goes — I’m not paying more to make this thing work. I already paid enough and it should work or I should be refunded. So now I’m stuck with a bad card. I really expected a company like BestBuy would only sell quality products and would stand behind the products they’ve chosen by making it easy to replace a defective one.

Too bad they won’t. I guess I’ll try somewhere else for my next SD card.

TraduireAfficher dans la langue originaleHave always been a fan of Sandisk, however today, there were none on Walmart shelves for 128GB. So thought I’d try this item. The packaging was a selling point for me, looked like it would be all that it was advertised to be.

Whoa, hold on a minute, this memory card is SLOW. Just like other reviews, if you want your files to write to the memory card in this Century, your in for a very long wait. To transfer 5GB of data (Jpg’s) to this memory card, took over 35 minutes.

In the future, I’ll stick with Sandisk, that company rocks, super lightening fast transfer speeds, of which this Iron Horse PNY can’t even get out of the starting gates. Buyer beware, I’d suggest if your looking for speedy transfer rates, you’d best look at other products!.

TraduireAfficher dans la langue originaleI haven’t had the best time shopping for a single 128gb micro sdxc card on ebay. I thought I’d be safe if I bought a card from Newegg. Newegg is great. However the card I got wasn’t “writable” and since it wasn’t writable I could not add anything to the card.

This was a totally different case than the 2 other 128gb cards I ordered on ebay. I can confirm from a message I sent to PNY that PNY doesn’t make their cards this way, and getting the RMA done was easy and fast (with Newegg).

So you might get a perfectly fine card. The card was a total of 118gb storage space. Don’t let my experience keep you from ordering one of these cards just know that I had a card that was not up to PNYs standards.

One more thing, don’t order just any Sandisk or Samsung card on here. Most of them are fakes. Since my card wasn’t any good it only gets 2 stars. It would have been 5 otherwise.

Ever since I got into digital photography almost 20 years ago, I have generally been a practitioner of the one big card approach to memory, as opposed to multiple smaller ones. From a dollar-per-GB perspective, it’s obviously more cost effective.

But when I recently got my 60MP Leica M11, I decided to try something different. Rather than get a huge SD card for the equally massive DNR files of the M11 (approx. 70-80MB each, so far), I decided to buy a 3-pack of these 32GB cards.

If anything ever were to go wrong – even though I’ve never had a SanDisk card fail – with a few smaller cards, I’d only lose some of my photos, rather than all of them. Plus, the M11 doesn’t do video, so I have even less need for gigantic capacities.

At blazing UHS-II speeds, uploading to my MacBook Pro has never been faster. Accelerating the workflow at the front end means less time waiting, which in the old days was the bane of my post-processing life! Speed and reliability is all anyone can require from their memory cards, and that’s what SanDisk has always provided.

Card was recognized as 1TB but no data could be written to it, nor would it format in Windows, Mac or any of my devices. Windows would give an error indicating the card could not be formatted. Trying the SD Formatter utility, the Format would seem to succeed, but If I tried to write a file to it later, the file would seem to be written – however if I ejected and then re-inserted the card, the file would not be there.

Eventually, an error would be shown. MacOS would actually hang during the formatting process, requiring a reboot. My Steam Deck would get stuck on rescuing followed by an error. Trying the KDE Partition Manager in desktop mode, I would get errors as well saying the device was busy.

My Switch simply indicated that the card could not be used. I have another SanDisk card that had no issues. SanDisk needs to actually test their cards before shipping them out, especially for expensive 1TB cards.

No problem with the product – fine! But, I bought these as a replacement for alkaline LR44’s which were being used in the metering system of a camera believing that these were the equivalent but would be more durable.

However, this silver battery delivers its power very slightly differently and would have given false readings in the camera. The SR44’s have since gone into other appliances without issue but be aware of the difference which sometimes, in some equipment, does matter!.

Difficult now to match quality of photographs with every one and their dog running about with smart phones and extension poles in back pocket for selfies. I bought this for my daughters forth coming wedding Dec 2016, and yes really happy with the camera, the quality is not David Baily standard photographs however it is fun (Capture the moment) instant camera and photos are in your hand within a couple of minutes.

You have to be careful and watch when pressing down on shutter – Make sure your fingers is not in the way!!.

Bought for a new phone for a friend – 8Gb is fine since all photos especially are backed up to the Cloud every other day or so. Speed of writing of photos is excellent : camera ready virtually instantly for next shot.

With the SanDisk label, I never even bother to think there might be data-loss at any stage. unlike some other brands. !.

Nikon list my D7000 as being completely compatible with this SDXC card and of course, it worked immediately from the pack. The massive 64gb only a couple of bigger SD cards exist, both 128gb and disproportionally more costly gives me Nikon D7000 16.

2MP 1600 RAWbasic jpegs my standard shoot 1500 RAWnormal jpeg 1400 RAWfine jpeg 1700 RAWs 6400 fine jpegs 12800 normal jpegs 25600 basic jpegs. As Im sure you know, cameras only show available picture number individually below 1000, so above are approximate.

Its also marked as a 10, denoting full highdef video usage. Theres a slight compromise over the bit more expensive 45mbs Extreme 64gb, this being a lesser Ultra and only 30mbs. Ive been using daily 20mbs Lexar pro 32gb cards in the D7000 up to now and these have been fine for general photography even short bursts of RAWjpeg on highcontinuous drive AND hidef video without hitches or buffering, so the speed of this Sandisk should be fine.

For sports or action enthusiasts or pros, then you should be looking at the top 95mbs cards. I have a 16gb Sandisk pro, for this type of work. Ive had my complete fill with memory cards now, going out with a bang with the biggest one Im likely to ever own rather a satisfying feeling.

I got this on sale for a fantastic price to hard to pass up. Such a great deal, I had to buy two of them. Performance is what you expect from Sandisk Extreme Plus UHS1 cards. Fast, solid, reliable. I only have a USB 3.

0 memory card reader, so I was not able to verify the claims of 170MBs seq reads but I did see 90MBs seq read and 80MBs writes on CrystalMark. This is a USB 3. 0 limitation and not the cards fault. As it is, there is not much point to getting faster on a UHS1 card anyway.

I suspect these are the fastest we will ever see in a UHS1, with UHS2 eventually taking over. These are compatible with everything I have tried, including my Gopro Hero 5 Black and Hero 7 Black. Tested 100.

With max settings, I have 4h17m and 3h14 capacity in each camera respectively, which is great. Being that batteries only last a little over an hour, this is easily enough for 34 batteries worth before I would need to swap the card.

Overall, very happy with this purchase on the deal price. I got these for what you would usually pay for low quality 128GB cards. No brainer. If these go on that deal again, I might just have to pick up couple more.

Dji recommends the SanDisk Extreme and this one is even a little better being the SanDisk Extreme Plus. The read and right speeds are a little faster on the Extreme Plus. 10MBs faster read and 30MBs faster write than the Extreme card.

It was on sale for less than 30 dollars so it was better to get a faster card for 4k video. So far it works perfect with 4k 60 frames on the Dji mavic air 2 drone. Faster speeds should be more future proof and perform better.

I have three Sandisk sd cards and all still work great. Beware of buying these cards online at unknown dealers because there are a lot of fake cards that do not perform as well in tests. I felt Best Buy would be the best choice to get a legitimate card and I did test its speeds and they are as advertised or faster.

Speeds can be a little confusing because the Mavic air 2 records 4k 60fps at 120 mbps. These cards are rated in MBs and 120mbps equals 15MBs. This card has 90MBs write speed so no problem with speed for sure.

Using these with a Thinkware dashcam. The cards go for quite a while before they hit their write endurance limit. I’m replacing these after maybe 3-4 years of light use. Heavy use expect 2 years. Priced very competitively and the full size SD adapter included is handy.

Probably my only request would be to offer the tiny MobileMate USB A adapter for those who use a desktop and not a laptop. I have both adapters now so I’m covered. Very happy with my purchase. Keep up the good work SanDisk!!!.

I have been using SanDisk MP3 players for years. They were complicated years ago, but have gotten easier & better with every new model. I use to buy strictly from SanDisk the company. But, I found this company & I can get the products new still in the box for better price.

I did get one that was damaged on delivery, They refunded it. & expedited a new replacement to me with their apologies. Impressive! So, I choose this company when I want a new one. I highly recommend this company & their products.

SanDisk has always produced five star products, with very high quality and a company you can rely on to keep there high standards of manufacture and the 128 GB micro SD card is no exception with everything you need to be able to transfer valuable information from one Card to another without the slightest chance of loosing any part of the transfer.

Easy to pick up and ready for use a simple reboot and everything running as normal new location found no blemishes what so ever. Used many SanDisk components over the years of IT and never had problem with anything what so ever.

I received the item, and it appears to be a legitimate, brand-new SanDisk SD card (the packaging is identical to their usual products). I tested the item from day one after receiving it, but, after three reformats with different file systems and done with different devices, I couldn’t get this SD card to work.

However, the seller was excellent. They honored a completely frictionless refund, and were very responsive to my inquiries. This rating is more for the seller than the product, which I’m mixed on recommending.

On the one hand, I understand that electronics do occasionally fail, so maybe I got a lemon. On the other hand, this price feels too good to be true. I got mine (a 512 GB SD card) for about $40, and, as of this writing, it’s available for less than $30.

That’s less than half of what you’d pay anywhere else, even online (Black Friday deals and similar aside). I guess buy at your own risk, but at least, if you go with this seller, they’ll take care of you if you do have problems.

This review is specific to B&H Photo. I almost bought a Nintendo-branded SD card for a fairly noticeable markup before I did my reading and settled on this. TL;DR this card is probably good enough for your Nintendo Switch (though some may enjoy the upgrade pick of the SanDisk Extreme tier).

From what I can see, storage media fraud (e. g. bogus SD cards that actually only contain a fraction of their stated capacity) is on the rise at several outlets, which is why it’s important for me to specify that this review is also a vote of confidence for B&H.

By selling the card directly to me (and not acting as an intermediary for a third-party seller), B&H has skin in the game, and gives me added peace of mind that they stand by what they sold. It’s a bit sad that I have to say this, but the card I received was (happily) exactly what it said on the tin – a card with 512 GB (~477 GiB) that gladly ingested its full capacity at an acceptable speed.

I do not notice any performance difference when playing games on my Switch, but I was buying this for the space, not for the blazing read speed.

I am giving this memory card a 3 star review. It DOES work. However I might be an edge case as I was getting this memory card to write a raspberry pi image to using the official raspberry pi imager tool.

It took 2. 5 days to write the image to the card and then 3. 5 days to verify the data that was written and then failed at the end of the verify stating that the data on the card did not match the data that was written to the card.

The raspberry pi would not boot. It stated that there was a microsd card detected but could not read the file system. I’ve written hundreds of raspberry pi images to other microsd cards and have never gotten this issue.

Formatting the card on a Mac and pc worked fine however, so I believe it would be a fine memory card for most tasks such as for expanding memory on a mobile device, gaming system or camera.

J’ai toujours eu des appareils photo reflex équipé de carte de cette marque, car c’est un gage de fiabilité et d’efficacité. Je me suis laissé tenté une seule fois d’acheter du premier prix; je l’ai vite regretté car carte non lu, photos illisibles etc.

direction la poubelle. Celle-ci, je l’ai destiné à mon smartphone. Le secret est qu’il faut toujours formater la carte sur l’appareil qui lui est destiné, pas ailleurs. Je n’ai jamais rencontré de problème avec cette marque (rapidité et sécurité).

Sandisk fait parti des quelques rares marques de valeur sure que je recommande fortement, tant au niveau professionnel (usage intensif) qu’amateur.

Cette carte SD est surprenante car sa vitesse dépend vraiment de la qualité du lecteur SD. Je l’ai testé avec des gros et des petits fichiers en même temps sur 6 PC sous windows xp-pro, win7, win 10 l’OS ne change pas grand chose.

Donc si votre lecteur est lent la carte le sera aussi. Par contre si il est rapide là elle sera rapide. Je l’ai mise sur un PC avec un lecteur lent donc.

Trs bonne marque , et trs bon produits. Il est important de bien connaitre l’utilisation laquelle est destin le support. Chaque carte , runi un paramtrage diffrent selon son utilit et utilisation. Amateur photo , je ne m’en sert pas pour la photo , que je prend sur de meilleurs supports , mais comme unit de stockage optionnels.

Cela me permet de dsengorger mon disque dur du pc , de trier mes photos , puis de stocker les images selon un choix pralablement dfini Et pour cela , ils sont excellents , pas trop lent , et financirement trs abordable.

I needed this for school and I love the brand. It works great and is reliable. It has lots of great features and it worked perfectly for what i needed it for. This is the only brand and type i will buy from now on.

I definitely recommend this brand and product!!.

I am so happy to have got this product. I take so many pictures on my phone to the point where it was lagging every time i would open my albums up. I have over 300 photos taken already with it installed and where my old sim card was slow on loading up the photos this is not at all.

I have not found any issues with this product at all, would buy it again.

It works! Nothing to complain about here. Helps me get my work done! There is not much else to say about it but it stores my files and helps to keep me organized. I would recommend this to anyone because it’s easy.

Ordered 2 256gb SD cards at an exceptional price. Turned out to be a mistake. Other reviewers warned about these being fake cards, I should have listened. As soon as I received them I ran a read/write test.

The test reveled over 30,000 errors before it was 1/2 way finished. The packaging looks authentic, but the cards are totally junk. If you still feel like trying your luck, do yourself a favor run a thorough test as soon as you get these cards so you can return it within the return period.

Walmart should investigate and ban this seller. IMOHO. On the other hand, Walmart took them back and issued a full refund. “Be careful out there. ” One star rating is mandatory.

Was a bit concerned about the non-english packaging, but needent have worried. The disc is in my phone and working fine. Would have liked an included adapter though. Good value – thanks.

they are not genuine ones, bought 2 and after one week use 2 raspberry pi they went off. totally burnt and overheating as hell .

Good quality product from a reliable manufacturer.

I’ve been using SanDisk cards for a long time. Mostly in my DSLR and video cameras. For a while, the SanDisk Ultra plus always fit the bill, until I upgraded my DLSR to a camera that shot 10 frames per second.

All of a sudden, the Ultra plus card didn’t do it anymore. When I got the GoPro 10, it practically regurgitated the slower cards. Enter the SanDisk Extreme PLUS. When I compared the read speed of the Extreme to the Ultra, there was an impressive 30% increase.

That speed was noticeable when using it with my DSLR. The Ultra couldn’t keep up with the 10 frames per second shutter speed, and 4 GB RAW images, and it buffered, a lot. With the Extreme PLUS, it didn’t buffer at all, and I tried my best to overload it.

If you don’t require fast read/write speeds, perhaps the Ultra is for you, it’s a good memory card. But if you have high performance device, don’t cheap out on your memory card, get the Extreme PLUS.

I recently went on a 2 week 2147 mile road trip. We started in Brooklyn to the Blue Ridge Mountains where we visited one of the caverns. From there we did 35 miles of the Skyline Drive. Then we headed to Atlanta to visit my older brother.

All along that part of the trip I was shooting like crazy. In Atlanta we did the Museums, the Aquarium and Ante Belem homes. MORE PHOTOS. Next stop was Charleston S. C. with two days of bus tours and many many more shots with the 750.

Finally we ended up in D. C. on Memorial Day and went to see the Viet Nam Memorial and listen to the speeches by retired Generals and Members of the various services (I’m from a military family going back at least 5 generations that we can trace).

I used up half the space on that chip without blinking an eye. When I got home and downloaded everything I was amazed at how great my shots turned out. Both the RAW and 16mp ones. SanDisk Extreme Pro is the one that works.

What can you really say about this… hmmm well its a memory card. Do you need a place to store some memory? Get you one of these. Now don’t go buying one willy nilly, because the price on these little suckers should not hurt your wallet.

They can also be used on ur nintendo switch. But 64 gigs just wont do for all ur needs here. Anyway, this will get the job done for your standard camera. It won’t be the best for a photographer camera though.

They need a faster memory card so look for a better memory if thats what you need it for.

I take a lot of pictures with my cell phone, and My SanDisk Ultra Plus microSDXC UHS-I Card with Adapter does not disappoint when it comes to the number of pictures and videos it will hold. I can save up to 4,000 pictures (16MP) AND 80 videos.

I also can save apps that are on my cell phone to the SanDisk in case my cell phone’s internal storage begins to run low. SanDisk is my to go to for extra storage.

Easily lost when not in use; but, why not in use 😉 Insert it and forget about it. Best write down where you put it in case your memory isn`t always so good. Very hard to find if dropped; be careful with it and wash hands first.

I was using it like normal but when I put it back in my camera it overheated and burned my sd card adapter and burned a spot on my micro sd card. I’m so mad. Invest in a better product to avoid this from happening.

After further research others have experienced this problem with the exact same problem. I haven’t seen anyone else have this problem with other products. This one is the main issue of this problem.

Great microSD card for Smartphones. High speed so can use as default store for Video and Busrt photos. Can also move Apps onto the card to free up phone memory yet maintain speedy loading. The inclusion of an SD Adapter allows you to plug in the card from your phone and access it via a PC or in a Digital Camera that takes a standard SD.

Good value for a high spec additional storage.

IšverstiShow in original languageThis High Endurance Micro flash card works better than the Ultra series in my dash cam. That one kept cutting the camera off and on and I read one user in a forum say they dont work in dash cams.

This High endurance was in a list of recommended cards. I put it in a new dash cam and after uploading the looped videos and viewing them, theres a definite minor jump in the video every 12 second. Not unusable, but mysterious as of now.

Otherwise it works fine. Will try a Sony 32GB card to compare. I cant imagine its too fast for the dash cam, but I learn new things all the time. After using it more, it seems fine and the jumping in the video is most likely related to the cheap Pilot dash cam.

IšverstiShow in original languageI use to love Samsung products, especially their memory cards because they have a reputation for lasting a very long time. But my my, has the time changed. I went back to SanDisk because they have never failed me.

Im using this in my dashcam and I have to say, its fast. I can capture 4k footage without any issues from my Rexing V1 Dashcam and I can throw this in my Yi 4k action cam without any warning message about it being too slow.

I dont do anything to my memory card. It ususal stays in the camera or in a protective case, so I dont know why my Samsung card crap out on me. Luckily I had my SanDisk card on me during a trip to Iceland.

I would have flipped if my Samsung card throws an error message about needing to format or being corrupted. If you want peace of mind, grab the SanDisk card, especially when its on sale. They are a steal.

IšverstiShow in original languageThis camera turns out to be very good for our needs. We have theft happening in our area and it provides enough detail about who is near or at the car at all times. It gives us the extra video and detail that our home security system lacks.

It has also been good for covering what is happening when we drive around. The only down side is that you cannot FF the videos when watching from the APP. You have to download the video to a video editor in order to see the portion of the video of interest.

If you are trying to capture another drivers license plate number while driving, it can be hard to see but if you upload the video to an editing software program you can enlarge it enough to see license plates up to three car lengths in front of you.

Customer Support needs some work. You cannot talk to anyone right away. You have to leave a message and hope they will return your call and you are able to see the call when they return your call. It is recommended to have it installed by a professional as it does connect into your cars system.

I was thrilled to open the pack pack, and mov 20-25 birthday family photos of much less than 1GB on this microSDHC. However, when I tried to re-open, SanDisc Extreme stopped responding. Tried many times with another personal laptop, still no response.

It just simpy peacefully died. As it had some personal photos, I destoryed it in a safe way. I trusted the SanDisc name but, it crashed like a cheap memory card. Disappointing. IMHO, it appeared promising at this sale price but, turned out as not worth spending any $.

Great addition to the Frameo digital frame. Extra storage for more photos.
