I have, on a SuperMicro 370DLE. The IDE is OK, but not great.
XYX:lserv00:~> s hdparm -tT /dev/hda
Timing buffer-cache reads: 128 MB in 0.74 seconds =172.97 MB/sec
Timing buffered disk reads: 64 MB in 2.83 seconds = 22.61 MB/sec
XYX:lserv00:~> cat /proc/ide/hda/model
It's a mostly-meaningless benchmark, but I get 34MB/sec out of the same
disk hanging off of the Promise controller built into the Asus A7V133. The
OSB4 really doesn't do IDE very well. If you really need the disk
bandwidth but don't want to shell out for SCSI, consider getting a cheap
(<$40) PCI Promise IDE controller and hanging your disks there.
