*edit made the same mistake as the user above and did not set the custom path to the external SD... this is the correct result 13.1/27.6.

That's 4096 cache and sio scheduler on paranoid 2.56 / android 4.12.

Sandisk extreme pro.

It might only be 16gb but they say up to 95MB/s read and write up to 90MB/s. I've gotten 35 on my computer for copying files.

I'm rocking a Samsung class 10 and it's about a year old. As you can see there's been no deterioration.

Bro, is your Patriot and "LX"?

I just bought one after I saw your pic and the benchmark results are disappointing compared to my class 4 sandisk (both 32gb)

You know honestly I'm not sure I sold the card a few weeks ago and then used to money to fund a 32GB Sandisk UHC1, which I regret. I'm on my second Sandisk card the first one lasted about a month.

May wanna peeek at this thread also.

With no brand preference, the newer samsung pro's are really good. 70 read, 20 write, waterproof shock proof...ect... slighty more then the sandisk ultras.

I prefer the sandisk ultra personally, but seems some people hear have had problems, this is just another alternative out there. it gets good ratings.

When it comes to buying memory cards now. unless you get a 32gb SD ultra class 10 for 10 bucks, go for the uhs-1. It will give you a little more longevity out of it in regards to replacing it due to becoming outdated. Also....more advice would be to not buy a memory card with less then 32GB of memory. a 16gb sandisk ultra uhs-1 costs $22 and a 32gb costs $28(to go the 64 is alot more spendy, but 32gb ones are the best buys right now). pay the 6 extra bucks, apps arent getting any smaller. GB's are going the way of MB's fast enough.

My Sandisk

On an MB886
Figured I'd share mine since I didn't see any with better speeds.
I've never had any problems with it, I use Foldermount with it with no problems, although I tried the swap script for an entire day with no success.

Edit: correction, I see some that have better write speeds

I don't need the room, but I want to start flashing roms.


I can't decide between 32g and 64g (which is the better deal now that the 128's are coming out)?

    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.

    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_Digital#Speed_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.
