Highpoint RAID cards..

From what I see Mac OS X Server 10.5, RAID 5 is still not an option for software raid which would be sufficient for what I want to do. Since it's a 2nd gen XServe G4 any hardware raid card from apple would be out of the question (and budget since its just used for personal stuff) seeing that the XServe G4 don't have PCI-e slots. My main criteria are: Card has to be PCI-X(This is a 2nd gen XServe) RAID 5 to get the most usable disc space Super performance isn't a real issue. Reliablity would be more important. I'm not looking for boot support data only is ok. With that said, does anyone have any opinions on the Highpoint RockeRAID cards, or any third party Mac compatible RAID cards, I was looking at [url=http://www.hptmac.com/US/product.php?_index=22]RocketRAID 2224[/url] and would like to see what other people's experience was with them? flaky drivers? poor performance? quirks? good experience? Thanks in advance, jerky
