I have changed my PCI-X card configuration for a couple of reasons. First, I wanted to remove a UL4D from the 100MHz bus to save it as a spare and second, I wanted to replace it with another SeriTek/1VE4 to run a WDC WD1500ADFD-00NLR0 Raptor1500-16MB cache.

G5-2.7GHz DP, ATI X800XT ME, OS 10.4.4, UL4D in 133MHz slot, nothing connected, 2x SeriTek/1VE4 in 100MHz slots, one connected to 1x Raptor1500, 8GB RAM. The Raptor1500 is in an external case and I have been exercising it for the last couple of days to loosen it up.

No way I can duplicate Boot's Quad and Raptor1500 results but not totally out of the ballpark. QB 2.1-100MB.
Boots:
100 MegaBytes, Read- 73.014 MB/sec, Write- 96.640 MB/sec

Mine:
Over the last few days, 100MB Reads as high as 77.455 MB/sec, Writes as high as 89.561 MB/sec, but on average this is what I get

The drive does haul and I'm pleased. Next to SoftRAID it with 4x Raptor74s.

Will get Boots and my results on the DB. k
