Q: microsdhc classes

Will the epic be able to make full use of a class 10?

Not the way it's configured in the stock manner. You have to increase the read ahead. Also a Sandisk class 4 will probably blow a generic class 10 away.

Also if it is indeed a generic card, be careful about where you buy it from. There are a lot of fake SD cards floating around the internet that are basically repainted 256mb cards set to keep overwriting data to appear larger than they are.

Also remember that the class of the card is an indication of write speed. Read speeds are pretty close to the same across all cards except that the higher quality cards(Sandisk, Kingston, etc) will read a little faster from what I understand.

Basically, a 32GB Class 6 card from Sandisk or another reputable manufacture is what you want.

It's a useful program, and seems to speed things up quite well. I also used a program called SD Tools: https://market.android.com/details?id=ales.veluscek.sdtools&feature=search_result to test the performance changes to determine the best settings. I found 1024 to give the greatest improvement with my card (32GB class 2 SanDisk).

Download This Program!
With it you can check your SD Card's Transfer Rate, Class and more...!

You have two choises:
You look on your card. There should be a little number in a circle. This is the class specified by the company (if this is true is another question)
You use a very good sd card reader so that it will not lower the transmission rates of the card and measure the speed. The up and down transmission speed specifies the class:
Class 2: 16 Mbit/s (2 MB/s)
Class 4: 32 Mbit/s (4 MB/s)
Class 6: 48 Mbit/s (6 MB/s)
Class 10: 80 Mbit/s (10 MB/s)

im using class 4 8gig and the transfer rate is above average and im happy
so if yr happy no probs ,

i get minimum of 5-6 mbps.

For 8 gig card a class 4 is suffice, but for 16 gig, 32 gig class 6 or 10 works best as it needs high speeds for data read/write! Hope its clear enof! :what:

I'd recommend any of SanDisk Mobile Ultra MicroSDXC Class 10 UHS-1, I'm using it and it's way better than any MicroSD i have every used before.

have you formatted the memory when you first put it in your device? try to backup your files and format it again then restore your files, if there is no difference in speed, go for class 8 or 10, but a class 4 is fast enough. make sure you unmount your memory properly

Lol class10... here in Brasil it would be soooo expensive. Using class4 32gb

Custom rom gives more space?

I recently bought a galaxy tab 2 7" 8GB, but I can only use 4 of it. Would installing a custom rom give me more space? Its a shame that they really only give you 4gb

No, you will need to jump through a couple hoops and leverage your sdcard slot, by using a swap script, or an app like foldermount, gl2sd, or similar. Personally, i used the swap script when i was using 4.1.x, but now i use foldermount. The p3113 swap script is on these forums, and foldermount is in the play store, or the thread for it, which are in the android apps and games forum, or software development, i forget which.
Oh yeah, every option requires root access.

Just a quick question since it's brought up. What class sd card is suggested for doing this method? I've read that class 4 is better than class 10 for doing this, but that was on my Xperia Play. Just wanted to make sure before I invest in one.
Thanks.

I don't know if it is true,but I had a class 4 SD card on my xperia mini,and i when I bought a class 10 16 GB,the phone was about 30% faster with swap then class 4 with swap.
So I believed in classes ;D

Class 4 = 4mbps
Class 10 = 10mbps
You tell me.

I have a 32 GB U1 which U1=Class 10 fyi.
My tab has 16GB storage but only about 12GB useable so it would make sense a 8GB only has about 4 useable.
Sent from my GT-P5113 using XDA Premium HD app

Class 4 will never be as good as a class 10. I am running a Samsung Class 10 UHS-1 70MB/s read and 20MB/s write card and that is about as good as it gets. Anything higher is not supported by our device (read and write speed-wise you would be over-compensating way too much).

I read somewhere that when using the sd card for apps and the such.
Ah, here it is:
This higher class # = higher speed across the board is a bit of a misnomer. Lower class (4&6) seem to have higher random access speeds, so when pulling up files lower than 6MB, it may behoove you to have a lower class card. Seems handy when pulling up photo and MP3. If you're transferring large files you may see speed increases for things like full movies or apps. Is it worth 10 seconds every now and then? I'll let you decide.

Yes, it definitely gives u a lot more space because stock roms are filled with bloatware (pre-installed apps), which according to me are useless. If you flash a custom rom it is not filled with all that crap and will give u a lot more of storage like if you have an 8gb tab 2 u will get only about 3-4 gigs of free space on stock but if you switch to custom rom you will have around 6-7 gigs of free space.
Sent from my GT-P3100 using xda app-developers app

No one has tried repartitioning space from system to data? System takes up over 1.4 gigs, so with most ROMs your wasting a gig of space.

[Q] Slow class 10

Anybody else with a SanDisk Ultra 64 GB class 10 / UHS-1 find the write speeds slow?
I'm pretty sure it's a genuine part. It's at 8 MB/s write with my laptop

Not everyone but some have problems with SanDisk 64gb class 10 i had one and mine kept crashing it wnt show my storage or wnt pop up in my computer .. I would go with a samsung.. Look around online and u can find a hood price for them specially winter/holidays are coming

So getting close to the advertised speed, like I have with every other SanDisk, is unreasonable?

Your sdcard works right? Slow or fast it works right? I'd be happy.

My card seemed to work fairly well until it crapped out. SanDisk is sending a new one out so I'll test it out once I get it.

That's like buying a brand new sports car with a turbo boost leak and then being like "oh well". My 2.3 GB nandroid backups take about 13 mins. So TWRP is writing much slower.

I suggest checking my thread on the SD card you may need to reformat it and clean it up. Also try ROM toolbox pro to turn the write speed up. I write at 55 MB a sec
