Hi all,
When I mount an usb stick with the option "sync" (USB 2.0) I got a
writing speed about 15 kbyte/s. Reading is ok (ca. 1 s for 2,3 MB).
It doesn't matter if trying as root or normal user. I only have to
unmount the stick and remount it without "sync" and writing is fast.
That means I write something on the stick (ok it's buffered) and
then I type "sync" as command and after 1 s it's done (LED from
usb stick turned off and data were written).
All this starts with kernel 2.6.13, 2.6.12 was ok.
I'm using 2.6.13 (not >)!
If it's solved in an newer Kernel, please ignore this email.

Hi there,
sync has been slow befor 2.6.13 also. This is "normal" because the FAT
is updated whenever data is written. This is not only slow, it will also
KILL your device. Using sync with FAT formated USB key will render them
useles really quick.
Try searching the archives it has been discussed before.

I had *exactly* the same problem. 2.6.13 honors the "sync" mount
option for VFAT, that's the reason.
Even if your device has wear leveling built in, you better not
use "sync" on a flash device. If you search the mailing list archives
(try searching for my nick "DervishD" and "usb-storage") you can see
that this issue was discussed before. I think it was a month ago,
maybe a bit more.
