Question: This may sound like a silly question but what is the adapter for?
Document: This thing works great. It is super fast at loading like it is suppose being a class 10. Plus came with the adapter. I highly recommend.
If you just need a lot of storage for something like a phone, this is a perfect choice. The adapter works great and I've yet to have any problems with it, even after partitioning it.
But the card is small. I wish it is the adapter that had attractive color. It is actually black, just like the Transcend one.Also Transcend came with a case. SanDisk does not have a case.
The 32GB card allows you to take a bunch of pictures and a lot of videos with your phone/camera. I like the adapter that comes with it too, as it makes uploaded your media to your laptop a breeze.
I ordered this memory card to replace some Sandisk Ultra MicroSD cards I had installed in my (and my wife's) galaxy S4 LTE due to some sort of incompatibility.These memory cards from Transcend did a perfect job to replace the Sandisk ones and I hadn't any type of incompatibility problem like I had while using the Sandisk cards.The adapter is a plus and the price is fair for a Class10 memory card.
Works like a charm. I needed 32GB to capture the most video that my new dash cam will support. I also needed the faster transfer rate, so the Class 10 rating was a must. In addition, the microSD adapter allows me to transfer the video onto standard SDHC readers like my laptop. This Transcend memory card comes with a plaster storage case; so when the microSDHC is in use, the adapter is stored in the storage case. When I bring in the microSDHC everything is stored in the storage case.
Not much else to say about this Transcend card. It's certainly fast enough for the phone, though I wouldn't do anything silly like pretend it was an SSD. The best SD cards now can read at about 80 MB/s (the overwhelming majority top out at 20 MB/s or so), but write speeds are still around 20 MB/s. Few cameras will benefit from a card faster than this one.
i'm very satisfied with this product and speed may vary depending what you used for it, for me is okey whatever atleast i got more speed to transfer with.
Failed in my BB Z30 after a week... may be a compatibility issue, so it may be fine for other applications. Replaced with a SanDisk and it has been working fine for months.
Fantastic value. I've needed this size, and the local offerings are at least 25-30% more expensive.I may order other sizes when I need them
Answer: This is a "micro sd" card so its quite small. The adapter allows it to fit in the sd slot on a computer.
