Wow! I have the fastest NAND! uahhuaaauh
Kidding!

just tested
I just tested my defy (stock US tmobile firmware + rom) using the default settings on the app (10mb/2k) and got:
NAND:

Poor SD Card

This performance is realy poor!
Can it realy real?
Only 2MB/s ??
Every today usb stick ist even more faster!
Maybe we have to use a nother tool?

I supose it's the hardware... or the unoptimized software..

What about Milestone 2 ??
Samsung I9000 gets 14Mb/s !!! REad and write!

I am not sure what's going on, but my Class 4 SD card seems to get 3.2/3.6. However I had tested the sdcard speed on a PC before and it's really closer to 8/12. Puzzeling.

new values with new SDCard, Transcend microSDHC 8Gb Class 6
SDCard:
Write: 5.27MB/s
Read: 6.05MB/s
NAND:
Write: 3.15MB/s
Read: 4.37MB/s

Why is nand so slow??
Maybe its Android 2.1?
Can someone test it with 2.2?

On my side, sure it's poor compared to the 'real' capacity of the hardware measured.
SD Card :
W 4.91
R 4.62

Internal Nand :
W 2.35

In quadrant score, the read/write stills scoring better than other android phones...
When i'm moving files to my phone, usually i get 5-8MB/s ( only large files 10mb+ )

I benchmarket the SD conected via USB with HD TUNE and results are....
No ****ING LOGIC!!
EDIT: The second test give to me 14MB average

I guess the benchmark tool is bullshi***!!

Guys it depends of the buffer size, if I select 1024kb of buffer i get:
SD
Write: 31,95 MB/s
Read: 114,94 MB/s
NAND
Write: 33,44 MB/s (More than SD Card)
Read: 112,36 MB/s

Slow sd card

General SD card problems
If your getting general slow SD card, issues with content on there being read, backup the importent stuff like photos etc and format SD card, seems the old android files on SD card may be messing things up. thanks orihuri for the tip.
If this didnt help and your still having prolems with slow SD card speeds download sd booster from the market and set the cache to 3000+ thanks to lws803 for the tip.
Did this both.. but still very slow sd card if I copy files
from pc -> sd = slow
from sd -> pc = normal
suggestions ?

Could you specify what "slow" and "normal" translate to in mb/s?
And what ROM are you using? Perhaps the problem lies there.

I use always android revolution hd, I had 4.1.x and the speed was ok.
I upgraded to ics 5.0.1.. at that moment I had problems with the sd-card
Now I use ics 4.0.3 --> android revo hd 6.0.
I did format sd card, and boost sd card but not helped.
slow = under 300kb/s
normal = 6mb/s +
So copying from pc --> sd is very very slow 300kb/s and lower.

Don't use the phones connection to transfer stuff then, use an sdcard adaptor and problem is fixed. It's something some user experience on ICS ROM's

You can try using cpu tuner to increase your sd cache size.....its set at a default of 512 on ics roms. I increased mine to 2048 and the write and read speed increased a ton.

It depends on what class is your card. if class 2 and/or 4 it's slow. I have class 6 and is fast ...

Thanks for the tips.. ill try.
My transfer rate is about 1,25mb/sec
Have been lot faster
Using ARHD 6.0.2

i only had this issue while i was on ICS based Roms. (insertCoin) Even though it was generally updated the issue was still there. Sometimes a reboot did the trick, but after some time i got annoyed and flashed back a GB rom.
Since 1.1.12 i am on Elegancia and there is no speed issue.......yet

Hey i have a 16gb class 10 micro sd and via usb when I am copying stuff over such as videos, music or anything, i'll be lucky if i get 600-700kb/s. Is this normal ?
I have a htc desire HD running ICS ice cold sandwich AOKP 7.4 (Stripper Edition). Im sure it did not copy things to the sd card this slowly before ?

Because SD to PC = Reading from SD
PC to SD = Writing to SD
Reading is always much faster than writing.

[Q] Performance and SD card restriction vs. NAND/ROM installation?

HTC HD mini
I read the most current version is photonic CM 7.2 - 2.6.35, but SD card is no longer really supported, is this correct?
At first I tried the SD card version 20.11.2011_r175-final.rar, so that I do not need to destroy my WM installation.
Everything is really slow, so I want to know how is the experience with a ROM installation, is it much faster?
Does the SD card speed make any difference?
I use a Kingston microSDHC 4GB Class 4. Is a Class 10 card much faster and is the reader in the phone capable of using a faster card?
With my SD installation I cannot install apps that seem to install some data on SD card, I always get an error “cannot save on SD or USB storage”, e.g. aTilt 3D Labyrinth. What is the reason for this problem? Is this gone with the ROM installation?
Thanx a lot
Andreas

you are wrong:
there is also a sd-card version of photonic !

micro sd card LOW write speed

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
Sent from my GT-I9500 using Tapatalk

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.

Compatibility Feasibility Speed and use of High Capacity MicroSd Card for adaptable s

I want purchase a new high capacity (64GB or 128GB) high speed (100Mbps 170Mbps 250 MBps) MicroSdcard for Swapping/Adoptable /linking apps through Link2SD/ portable (adoptable) storage
so i want to confirm compatibility feasibility speed performance my external sdcard slot/tray/reader/chip/hardware should have according to my device and Android lolipop 5.1.1 support.
High capacity MicroSd card comes with pre-formatted extfat file system but my mobile manufacturer technical specification of mobile device says it supports up to 128gb and fat32 file system
There are many available sdcards Micro i want to know that type (SDHC SDXC) UHs speed Class (UHSI UHS II) Video Speed Class (v10 v30 v60 V90) and App performance class (A1) Speed of (90 Mbps 100Mbps 170Mbps 250MBps) its confusing which will be compatible feasible and best for adaptable swap and give optimum performance for the purpose.
secondly there is not use of extra speed or video class card if mobile Device or Android supports works on less speed.
Before purchasing to decide i want to confirm and check my device and understand clarify following questions and queries to decide which external sdcard will be compatible for my android lolipop 5.1.1 OS and device:-
Can high capacity exfat be forced to be used (through mounting it inboot init) in android or phone through mount commands without damaging phone Android os or SDcards protocols and will all apps/ os file manager support it if yes then
*-kindly tell me commands step by step procedure for it.*

if not then can high capacity card be formatted to Fat32 if yes then how can i format and will the card give the same performance speed performance as in exfat to fat32 without damaging phone android OS and SdCard

In android Lolipop 5.1.1 file system (ext4) whats the block/buffer size it use to sequential and random write/read on external sdcard is it 512 bytes/ 4096 (4kB) /8096 (8KB) /512Kb /512bytes how to check or it depends on which filesystem the sdcard is formatted with then what block size it writes individualy in filesystems of fat32, exfat, ntfs and ext4

For suggestions I have pre-tested through androbench app
a) internal memory of my device through writing 64Mb file to /data/
(ext4 partition mounted) (64Mb file used for testing)
Code:
sequential read 128 MB/s
sequential write 12 MB/s
random read 10.93 Mb/s 2800.4 IOPS (4KB)
random write 3.9 Mb p/s 996.31 IOPS (4KB)
is there any restriction in device or android should we need to match
externalsd speed performance with internal sd as we have we can use
external sdcard as internal either by swapping/adoptable /linking or it
will work in more or less performance to
b) External memory of HP SHDHC Class 10 16GB (still i want to switch over
to high capacity card) of my device through writing 64Mb file
/external_sd/ (fat32 partition mounted)(64 MB File)
Code:
sequential read [B]35.56 MB/s (printed 95MB/s)[/B]
sequential write 8.6 MB/s
random read 4.36 Mb/s 1117.58 IOPS (4KB)
random write 0.53 Mb p/s 136.38 IOPS (4KB)
Hp printed 95MB/s but result is 35.5MB/s now its device result,fat32 file
system result or sdcard performance result don't know how to
differentiate it .
