Customer Ratings & Reviews

I have 2 of these saying corrupted. Hoping this one works better.

There are cheaper alternatives of this card by competitor brands.

Many year this is good price but now was little storage.

Works fine, but the storage runs out really quickly.

Bought new washer & dryer & all new connections & install from Best Buy. Dryer quit working & burning smell. Referred to Whirlpool repair service, quickly serviced dryer & found loose power cord in back of dryer, which was installed by Best Buy. Entire wiring harness burned & needs replaced. Whirlpool does not cover cost of new power cord, since I purchased from Best Buy. Visited store in person & called customer service, only to be told no, it's been past 90 days. At least another week until dryer will be repaired & Best Buy won't even be reasonable & cover the $19.99 power cord they sold & installed poorly. $19.99 power cord unfortunately is going to cost Best Buy a longtime & frequent customer.

The SanDisk 64 GB micro SD card was on sale and I decided to purchase it to use with my new Samsung Galaxy S3 phone (which does recognize the full capacity of the SD card). This is very nice as it does allow me to store lots of photos, videos, apps, and music on my phone more than the 16 GB of internal storge. Plus I am able to plug this SD card (with adapter) into my computer to transfer such files off or onto my computer. Also a great way to backup other data on the phone in case the phone crashes and the internal storage of the phone is irrecoverable. For me, SanDisk has been a reliable (if not a little expensive) brand that works well and I am glad to have gotten this on sale. Only bad thing about this micro SD card is how small and easy to lose it can be if one is careful, but honestly that can happen to any micro SD card.

This was actually the second memory card that I purchased, the first one was fine and works without a problem, This one unfortunately didn't work out of the box, it could not be recognized when inserted into either phone or camera and would not format. This is the first time that I have had a problem with a Sandisk micro SD card and was surprised, but have seen other reviews showing problems with this size. Hopefully they will iron out the bugs soon.

Even after performing a low level format of sd, it still causes my phone to crash whenever data is used that is stored on this sd micro. Many similar reports of this problem on blogs.

The item was defective and I returned it My tablet could not recognize the storage disk

I got this SD to add more storage to my phone. Everything I tried to transfer over. I can't

The Samsung Ultra 64gb microSDXC card works perfectly in my EVO 4G LTE; you are NOT limited to 32gb. Just insert the card and format it in the phone and it is ready to use in less than a minute. I have over 40gb of video on the card right now and it works flawlessly. Although listed as a class 6, the card I received is a class 10. Thanks to Best Buy for the great sale price!

Not gotten yet How can u review something that is 3 weeks late. Still have no idea when it will arrive.

Missed the Holiday-time special, but got this when they came back in stock for ninety-nine bucks. What a deal! Works in all the devices I've tried once formatted to FAT32 including my EVO 3D and my HTC Thunderbolt. I also have an OG EVO 4G and a Samsung Epic 4G that I'm going to try it in. The card is FAST and you can tell the read-speeds are phenomenal. SanDisk is the only brand I trust my mobile devices have been burned on every other brand including Kingston. Card formats to just over 59GBs which if you need more storage than that, you probably need to get out more.

I saw Best Buy had this uSD card on sale (it was sold out within a few days and off sale). I am using it in my Samsung Galaxy S2 (AT&T) phone running Android 2.3.4 (Gingerbread). I installed it in my phone, formatted, and close to 60GB was on tap. I used SD Tools to test the read/write speed (got 7.1MB/S write and 21.1MB/s read.... within spec for a class 6 card). You pay a premium for the 64GB capacity, but it is nice to have all that storage (I use a lot of its capacity for movies and music).

The Item did not work with my tablet, I tried two of them and it still did not work.

This micro SD card provides tons of storage space and works well with my phone (Samsung Galaxy S III). I had no issues loading it from my computer and it was instantly recognized when I placed it in my phone.

I got this on a Deal of the Day for a great price, and my (AT&T) Samsung Galaxy S III natively supports SDXC, so there's was no need to reformat or do anything special. It feels just as fast, if not faster than my old Class 10 32 GB Micro SDHC card Performance of the card is great, video recording and camera shots are smooth. I'm very happy with this card so far.

I got this card in hopes that it would work well with my HtC Evo, and sure enough it works like a charm! Very happy to have the extra capacity. No glitches what so ever. This card teamed up with my Evo sure beats paying $800 for an iPhone with the same capacity. Last but not least to get this card for $99 was just icing on the cake indeed.

I bought this to expand the storage capacity of my Microsoft Surface Pro. Adding an additional 64GB of storage space was a huge increase as the tablet only has 128 to start with. I would have bought a 128GB memory card if it was available, but this is currently the largest that SanDisk makes in this form factor. Great product and super fast. I am considering buying another one to put in my cell phone as well.

Works great in my phone, lots of room to put video & pictures. Speed seems to be pretty good also, nothing super speed but not slow either. Comes with a SD adapter, haven't used it yet but will come in handy later on.
