  1. I ran HD Tach 2.61 on my hdds just so I could find out which of my hdds are the fastest and was kinda astonished when I saw the results.

    Note that I have a fair few hdds in my system.. 4 on my onboard raid controller (Highpoint) 1 on my main IDE ports (the others being used for burner/dvdrom) and 1 u160 (Adaptec 19160 Controller)

    How the hell can my spanky u160 Drive give such a crap result compared to a bog standard IDE Drive? It is running as the system drive tho and you can clrearly see the spikes when it was accessed during the benchmark but check the CPU % and Average read rate ? wtf!

    now for the scsi drive....

    I have had a play with the scsi card bios options and the scsi tab options in XP but the results remained the same, even running it with all unneeded processes closed still didnt help :(

    If any of you have a similar setup and can help me increase performance then plz reply!

    I seem to recall something to the effect that windows XP has problems with SCSI. apparently SCSI hard drives are unable to perform at optimum with XP.

    it's been awhile since I read about it and since I dont use SCSI I really dont remember all the details.

    I thought SCSI was (supposed to) faster :blackeye:

    Access times are a hell of alot less, and performance is better (im having problems heh)

    + the fact that I can have 14 scsi devices per channel on top of my 8 IDE devices.. and yes I use all 8 IDE devices :)

    I was just about to post that same article ISS.

    I thought I remembered seeing a reference to speeding up SCSI in XP on a tweaking site but can't seem to find it now.
