I am looking for recommendation for a 32Gb Micro SD card that is the fastest and most stable for use in the AT&T Note.

Currently I have the following but they're not good:
- Kingston 8GB Class 6: REALLY slow - tansfer rate below 1 Mbps
- Transcend 32GB Class 4: slow - transfer rate about 2-3 Mbps

Both were bought from Amazon and as you can see, even a Class 6 MicroSD can have lower performance than Class 4, depending on the manufacturer.

You can check your MicroSD card speed using this tool from Google Play. The screenshot from that app shows some insane card speed, as shown below:

These are the same SD card. A Polaroid class 10 that was on sale the other day. This is the link for the card.

This was my first test taken a few ago.


This was taken right after on same sd card.

Thanks all for the recommendation and the screenshot!

Looks like Samsung and Polaroid CLASS 10 is the way to go. I will research the price and buy on of these.

By the way, a friend of mine recommended the NEW Sandisk SDXC. They seems to be more expensive, but if the performance is similar to regular MicroSD, what will be the advantage?

I think most any class 10 will provide similar results. There are some that guarantee certain speeds, and they may be better performers, but you'll often pay a bit more. The class refers to the speed, most manufacturers will report their best case scenarios to qualify for a higher class rating. http://en.wikipedia.org/wiki/Secure_...d_Class_Rating So you'll find some class 10's do out perform others and such.

SDXC just refers to the capacity the cards can support. I believe SDXC supports up to 2tb vs SDHC is up to 32gb. (there are other technical factors too)

Just be sure that it is indeed a MicroSD card, and not just a normal SD card.

Got mine @ buy.com website -
32GB , Class 6 for $19.90 + free ship ( came via post)

Just used the above testing ( was curious)

Got speeds = write = 10.3 reading = 14.4

So gota be worth it > not sure 64Gb (1$ per GB)is worth the money @ moment
