Hi. i have or actually had the same problem, average speed from IDE to
SATA was 5mbps. Then i tries to tune with hdparm and sdparm - nothing.
But i noticed that I coudn't set to use UDMA mode (yeah, hdd support
it), so i tried to set it in BIOS. BIOS saz that all settings is auto
and it use the fastest mode, udma5 on segate(5yrs old) an udma6 on
hitachi (a few month ago). But after switchin from auto to udma5 and
udma6 i get min 20mbps from ide to sata =) Dunno why, but it helps.
Actually I have average speed from ide to sata ~30mbps, but I just mv
2gb, I should make some serius tests in it... later =) BTW, self-copy,
move from one partition to another (on sata hdd) goes with the similar
speed.
Yeah, one more thing, speed is very various, starts from 60-80 and goes
down to 50 - 40 still there and goes ~17-25. Dunno why. Maybe my IDE is
to slow for SATA.
Here is some data about my
#sda = IDE, sdb-sata.
#motherboard ASROCK P4DUAL 915GL (nop, it is old 1-cpu mb =)), 1024 + 256
DDR1(tuned to 2.5-3-3-4, IIRC=)),
#CELERON D 2.4 (works on 2.7, I've overclock bus from 133 to 150)
