The boot and main storage drive in my Quicksilver is a 120GB IBM 120GXP I've had for about two years. Its an ATA100 drive but I've got it hooked to the G4's onboard ATA66 controller. I get about 22MB/sec (Xbench) from it, but obviously I could be doing better! When I looked up the G4's specs yesterday and saw it was only ATA66 I was stumped for a few mintues...why would I buy this drive and not take full advantage of it? Then I remembered! I'd bought it waaaay back when I was trying to run 10.2 on a series of idioticly upgraded pre-G3 Powermacs. That was really a pain, I can't believe I still liked X enough to get a G4! Anyway the drive had been hooked to a Sonnet Tempo Trio at the time which had to go once I decided to get a real G4.
So now I want to get this drive running at top speed again. Is anyone running anything similar to the three options below?
- ATA133 PCI card + IBM 120GXP
- ATA133 PCI card + 2 IBM 120GXPs and OS X RAID
- ATA133 HW RAID PCI Card + 2 IBM 120GXPs
All should give me some increase. The ATA133 cards have fallen to around $65. The ATA133, second drive, and software raid would run me around $150. The same option with a hardware raid card would be a bit over $200.
Barefeats.com tested setup #3 using these exact drives and got 110MB/sec - a big increase over my 22!
Can anybody post some results from 2 ATA133 drives using OS X's built in RAID software?
I don't have any reason to dump the 120GXP since its working fine. But rather than buying another should I switch to two newer, smaller, faster drives and move the 120GXP to another system or use it extra storage?
Go with a single SATA drive and add a second later?
Hope two 73GB 15K SCSI Cheetahs mysteriously arrive on my doorstep?
