I have tested the read/write speeds using sd tools with 3 different sd cards: 4gb class 4 sandisk, 16gb class 10 samsung, and 32gb sandisk uhs1. It seems that each card doesnt exceed 4mb/s write and 8mb/s read speeds on my e4gt on calkulin gb rom 3.0. When these cards are tested on my pc, i experience the correct speed ratings.
Is there a cap that is on the e4gt that i need to modify? I played with the cache sizes 128 2048 3072 and 4096, very minimal changes and all tend to fall in the same speed ranges stated above.
I tried switching different kernels but still had no luck. Any ideas? Thanks in advance.
Could it possibly be Calkulins GB 3.0 rom? I would hate to flash another rom just for trial and error if someone can confirm it's not the rom.
Running cm9 beta got 4mb/9mb. Card is an older 4gb sdhc sandisk

Thank You for that info will be looking for a 64card asap.....
i dont know if i would waste the $ on a class 10. I bought a class 10 232gb and through the phone i only avg roughly 7mbs write speed and 25+ on the read.
Bought my 2nd gs3 and it has 12gb of storage and not 16. Should i return?

No.. that's how much they all have out of 16GB that you can use.
Sent from my SGH-T999
It's formatted to be less, and about 1-2 GB is reserved for the system.
But phone says total storage is 12. Kinda dumb

Because the total storage you can use is 12GB. If you want to see 16GB somewhere go look at the box.

San disk is just fine. You can get one on amazon for under 20. If you do a lot of podcasting I would suggest getting the apps2sd hack in development.

san disk is fine. dont even bother with the premium lines, as they are more geared towards cameras. Also I read a few reviews on them in regards to using them for android phones (sgs3 was part of test) and they stated they saw no real optimal improvement compared to the average black san disk micro sds you can buy..
Find one on ebay, preferably in the US and not China, Ive seen 32gb go for like $12 free shipping, sometimes cheaper!

1 year ago, class 10 cards performed worse in random access (mostly used for apps and games), but apparently the newer class 10 cards perform just as well or even better than lower class cards. So I would suggest getting a SanDisk class 10 card, they are currently considered being one of the best.
Yeah, i ordered a class 10 high speed SanDisk SDXC card and was just wondering. Thanks for that answer though. Quite helpful. Just need an answer to the second question now

Hey KindaUndisputed,
If you're interested in seeing which SD card will perform better for you, you should test it with CrystalDiskMark 3. It's really easy to use and you'll mostly be interested in looking at the small byte ranged 4K random read/write speeds. This is important for running ROMs from SD or games and things.
I've noticed that my SanDisk 32GB Class 4 and Samsung 32GB Class 10 are pretty similar, so it's kind of just the luck of it I guess. SanDisk is usually pretty reliable though.
Thanks for that response, will probably try that, I although I think I'll be sticking with the 64GB anyways as I need the extra storage.

Oh yeah absolutely. Just if you wanted to test the speeds of some other cards in comparison to the Mobile Ultra. I'd have to think that that 64GB card would have superior speeds in every category though.
Yeah, thanks again
Sent from my R800i using xda app-developers app
All of this talk about class 10 cards having bad random access speeds was valid a year ago, not any more. Times change and with it so does technology. A decent class 10 card nowadays doesn't have these problems.

I will have a look, i can't seem to find any class 4 SD's at 64GB, only 6, 10 but i have had problems with a 32GB SD class 6 card before.
that's the UK as i'm from the united kingdom, it probably be worth going for a class 10? ultra or mobile ultra? is there any difference?
http://www.amazon.co.uk/s/ref=nb_sb...ywords=64gb+micro+sd&rh=i:aps,k:64gb+micro+sd
I'm from the UK, that's the one (the first one) I bought, from Amazon as well. It's quite cheap really. I don't know about drastic changes in speed but I don't think there are many cheaper 64GB micro SD cards anyways?

Sent from my SGH-T889 using xda app-developers app
well the ROM is about 835MB
that and 16GB is 16 x 1024MB = 16,384MB,
however they are using 1000MB in a GB when they rate these so they are saying 16,000MB which is actually 15.265GB minus the 865MB for the ROM, down to about 14GB available.
Disk manufactures measure Kb as 10^3 vs the way computers measure Kb as 2^10. As you can see, 1000 <> 1024 so you have a discrepency. Also, the formatting has some overhead.
