dd if=/dev/zero of=/dev/da0 bs=1 to 15M
runs, 13-14MB/s from actual files copied
in mc to flash and 36-39MB/s file copied
from flash to hdd in mc.
dd if=/dev/da0 of=/dev/zero bs=15m
gives 33MB/s read.
and this is incredibly high as of any pendrive.
Consider few things:
- pendrive flash mappers are incredibly dumb, they work in usable speed
when you do linear write only.
- today lies are standard. never believe in stated performance unless you
measure it.
even recognized in FreeBSD as device.
what i do with any pendrive:
dd if=/dev/zero of=/dev/da0 bs=64k count=1
newfs_msdosfs /dev/da0 (if i want FAT filesystem)
partition table is not needed in any OS, including Windows starting from
XP.
msdosfs in FreeBSD isn't high performance too.
try writing small amount of huge files.
