Hi guys. When I try to copy something from my PC to phone via USB cable, writing speed is about 400, 500 kB/s although sd card cache is set to 4096 kB or 2048 kB.
But when I put sd card into card reader, writing speed is around 6 MB/s. I put my sd card into another X8, and same thing. Speed stays at 400, 500 kB/s.
The card is Kingston Micro SD 4 GB Class 4
Format it once.....

i have a sd card (1 gig) but it takes ages to transfer data to it..
for example it takes up to 50 min ot transfer 250 mb
is this normal? this really sucks!!!
Are you using a card reader writer or using activesync direct to your phone?
now activesync but i tried a 1.1 usb card reader writer and it was still crap!
well if it's also slow with a sd card reader then it's not really sd related and the only thing people can say to you is
1 try an usb2 reader
2 get a faster sd card
Can anybody tell me how I can fix my transfer speed with ActifSync 4.0.
Because if I upload the transfer rate is about 100 kb/s.
Anyone with the same phone and sd-card please help me.
Thanks

If you want faster transfer speeds use a card reader. Using activesync the data first gets moved to the universal, then from the universal to the memory card. This is very slow due to the limited bus speed of the universal.
But with my 512 mb card, I get normal speed. I think you dont understand how slow it is. Let me explane.
512 mb > 3 sec 1 song
4 gb > 30 sec 1 song
Yesterday I bought a Transcend 4GB 150x SD card.
It's very slow; not only when using it in my HTC Universal, but also in the cardreader in my PC.
I'm going to return it tomorrow...
Jan after reading some reviews they say that it is one of the fastest cards. I think the problem is with the reader. I can now transfer at usb 1.0 speed with Card Export II.
Are there any app. with 2.0 support?
Hi guys,
i just bought a class 6 high speed microsd card at target and i did some experiments before putting android on it.
I connected the phone using the disk drive mode, and
I transferred a big file using the standar 32kb cluster size (formated with the phone) and i got write speeds up to (4.31 mb/s)
then i formated the same sd card using windows 7 and set the cluster size to 64kb
the i transferred again the same file but this time i got the speed up to (5.9 mb/s)
android boots fine, and i notice a big improvement against the class 2 card,
i wonder if there would be any problem if i use this 64kb cluster size? is anybody else using this cluster size? thank you,
In theory: bigger cluster size giving better performance, but you waste more disk space.
Everything will be ok.
ok so apparently its best to format to FAT32 32cluster right? but is FAT32 the same as just FAT 32cluster size or not? having problems achieving both
you cant choose these options through sd format on the phone and if i try to do it through my pc via usb Disk Drive connection, on windows format i can choose either -
file system: FAT (default)
Allocation unit size: 32 kilobytes
OR
file system: FAT32
allocation size:lots of options but not 32!
also tried a pc card formatter i saw in another post but that doesnt give many options and when its formatted it says its just to 32
card is a sandisk 2 gig not sure of the class? just came with the phone
maybe a 2gig micro sd doesnt support 32k clusters in fat32?
try upgrading to a 4 or 8 gb card. maybe even a class 4 or 6
yeah maybe. might have to invest in one. surely that would then make android more reliable also???
I've read and found through my experience that my Roms run best with a 4096 cluster size. Any time I tried another size I would get stuck in the crazy fsck check with a large amount of those files all over my card. Though I have also been told that bigger is better.
Basically all my sd cards have been formatted like this.
format x: /fs:FAT32 /a:4096 /v:android /q
x - being whatever drive you have assigned to your phone
android - being whatever label you wish
Never a problem since.
I use 64 cluster size formatted using pc and it works great for me. Supposedly it gives you less space but faster r/w speed. I've never had an issue with space using stock 16 gig class 2 card and runs every build I've flashed great.

Hi I need more space for my duo 11 and the cheapest way i believe is to buy a micro sd card to increase the size(Don't know if i can swap my hard drive from 128gb to 256gb). I spotted this micro sd card which is pretty good but don't know if i can utilise it to its maximum speed. The card is "Samsung UHS-1 Class10 PRO Micro SD XC 64GB Memory Card", I know duo 11 supports SD XC but it also needs to support UHS-1 for it to use it up to its maximum speed.
On a side note it says
-Read Speed: Up to 70MB/s
-Write Speed: Up to 20MB/s
Does take mean if i transfer files out of the sd card it can go up to 70mb/s and if i want to transfer files from my hard drive to the sd card the transfer speed would be 20mb/s??
Thanks in advance!
That would be the correct speeds assuming all is perfect and no overhead.
You also need to verify that the reader in the Sony is not connected through USB 2.0 or you wouldn't see 70MB/sec reads, more along the lines of 30-35MB/sec.
The duo uses sd cards not microsd. You can use a microsd card with an adapter but a sd card will be cheaper.
I have a 256gb sd card in mine and it works but it's not particularly fast.

That would be the limiting factor as far as the SD card is concerned yes. Operating system overhead would slightly reduce that. Also there would be a limiting factor in what the hard drive read and write speeds are or memory stick or whatever it is the files are being transferred to and from.
