Good to know that the card I just bought performs so well!!
Is this the microsd pro rated at 70mb read and 20 write?
Can you test your read write speeds with the app SD card tester or a1 SD bench? I'd like to know if 18read 12 write is normal when tested in with a phone app.

yes this is the samsung pro 64gb micro sd rated at 70mb read 20mb write
i ran the a1 sd bench- using longer testing . (without this box ticked the ext sd was a ridiculous 500+mb/s read 13mb/s write)
internal mem- read 135mb/sec write 71mb/sec
external sd - 21.77mb/sec read , 14.09mb/sec write
Is there instructions/links that are specific to the note 3 on how to test the speeds?

not really rocket science. can use that a1 sd bench app. there are other apps arounds.
or time how long a file takes to transfer with a stop watch. then calculate the transfer speed , which is what i did with that single large file. since i'm mainly transfering movies/shows across, i figured this was a better real life test than using an app.

Class of sd card? This usually indicated how fast the sdcard is. For example class 4= 4 mb/s read and write speed. The higher the class the faster ur sdcard

Have you tried removing the SD card from your phone and connecting it to your PC with a SD card reader? I usually get better speeds that way.

I have the same problem, I have a samsung class 6 microsdhc 16 gb, and i get write - 2.5 mbps and read 11-13 mbps
You could try with a class 10 (highest class) SD card. Or use a card reader. I've also read that if the port damaged or old, etc., so try putting it in another port. Maybe that'll help.

I think the mod of vold.fstab is enough, but I dont know the internal drive assigned number is. If you or someone could find this out, maybe it will work.

Hi ,
I have problems with my micro sd card class 10 (16 gb) due to low write speed (write speed should be around 10 MB per sec.). I have been using this sd card since my HTC EVO 3D without a problem.
With my SGS4 I never get more than 2 MB/s of write speed (transfering files from pc to phone). I was also playing with sd cache (I tried 1024, 2048, 3072, 4096) but still nothing (SD booster apk).
I att. also benchmark of my card (done with A1 SD Bench).
Thank you in advance.

my Sd card also seems to have a low write speed which is weird considering its the same 32gb sd card i had in my old s3

I am using window7 x64 so I tought maybe something is wrong with my PC but I did not find any solution on google regarding this problem. I had tried a lot of aapks for changig sd cache but without success - I can change cache but I get no difference in write speed.
how have you tested the write speed? If u just link the phone to PC and copy files from pc to the SD Card, it should be slow, because gs4 has no hard disk mode (I don't know if with some apps can make a real hard disk mode, I always copy big files with card reader).
If u want to test the write speed, try to copy a big file from interne SD card to the extern SD card, note the copy paste time and calculate the speed.

Also HTC Evo 3d has not have hard disk mode and I get speed alway almost 10 Mb/s when copying from pc to sd.
I have a issue with microSD card with the stock rom (jb4.1.2, sprint).
When I insert my 32gb samsung class 10, the phones tell me that is corrupted.
I have formatted with PC (windows 8.1), with the phone (in android, not in recovery) but same issue.
I also run chkdsk from windows to fix the problem, but nothing..
The only way to get my SD working is mount and remount from android settings until it makes a strange "mount loop" and to the end phone accept the card.
Every reboot or every time I get out the card I have the same issue.
I also have issue with spotify: aftero 400 / 500 MB of downloaded cache it tell me the memory is finished.. but I got 10gb left in sd and 2 in internal.. I think issues are connected.
Have you tried a different SD card? Perhaps that card is in fact corrupt.

With CyanogenMod (10.2 and 11) works perfectly on my phone, with my old desire Z works.. The problem is only with original sprint rom..
Test: 64mb microSD works ok.. (don't ask me why I have 64mb microSD )
New test: my brother's 64gb kingstone class 10 works perfectly, my samsung 32gb class 10 on my brother's huawei p1 with CM10 works perfectly..

Remove the card and reformat it in a PC, you may have to delete the partition table and create a new one if it was adopted storage due to the encryption.
Also, I would look at the app called SD Insight and verify the card is not counterfeit, this is more common than we would like to admit. BTW, a Class 10 card may not be fast enough for adopted storage, a minimum of UHS1 is recommended and UHS3 is preferred, due to improved write speeds.

I don't like the sound of that. Is it showing up as an actual drive (E.g. C:\ D:\)? If so, run a chkdsk on it. Search for "CMD" on Windows, and run it as administrator. Then type "chkdsk /f <your drive letter>". It should attempt to repair any broken areas of the card, but if it can't fix them it may throw up garbage text.

Windows will only recognize the first partition on an SD card.
TBH, with the price of SD cards if you can't quickly fix it by deleting all the partitions and reformating, throw it out and grab a new one.
