...to bring in another perspective, my machine has two IDE's, but after
running out of that avenue of expanding, I was finally forced to get an
SCSI drive. The result? Not only does the SCSI drive always demonstrate
considerable lower transfer & seek rates than either of the IDE drives,
but according to kernel profile dump the SCSI drive is also, when used,
eating up remarkable portion of the machine time. Ofcourse I'm using
relatively small SCSI drive and non-busmastering SCSI interface.
Unfortunately I can't come up with exact statistics and model codes as I
don't have them here with you, but this is just to throw in the reminder
that other things than "SCSI vs. IDE" matter - perhaps even more so.
There's good and there's bad hardware out there, on both arcitechtures.
(And to tie it even marginalyl to one of the lists I'm posting to, I
suspect the Linux adaptec-drivers are also partially to bleme for this;)
The getphase() thingy is a real sucker in terms of CPU...
