Interesting-I just did a comparison with my upgraded Sawtooth(Gigabit):
I have two 120g Maxtors in the machine now-Jag & 9 on one, Panther on the other.
Would I get much more performance, that I can see, feel, by striping them?
I was thinking of taking 2x80g I have to make a raid just for the OS, main apps-Photoshop, Final Cut, Performer, etc.
I was also going to get a ATA-133 PCI card for the 120's, and use them mainly for media files. Also looked at the PCI raid cards-can I do a raid on one channel, and just run straight master/slave drives on the other?
Later will upgrade the box again with single 1.4 or Dual 1.4, etc. once the prices start to drop a bit more. Think Gigadesigns is coming with new Duals soon, which will give Powerlogix more competition on that front as well. I 've been playing with a friend's 1.6 G5 also-very nice machine, but for my purposes (non-professional on the above apps) my box is "almost" fast enough-Panther does speed up the finder, for sure.
(this Xbench run was with Radeon 8500, not Rage 128 Pro as in notes-though I've found the Rage 128 Pro and GeForce2 both bench higher than the 8500)
