RAID controller for $600 AUD
I'm looking at picking up a new SATA RAID controller, with a budget of around $600 AUD. Needs to actually have an on-card processor and cache and support eight channels, battery backup not essential. Must run on PCI-E, not PCI or PCI-X. Needs to support RAID-6. Will be used primarily on a Vista machine, but .nix support (specifically Slackware) would be nice. MACOS I'm not fussed by.
Current front runner is the Highpoint RocketRaid 3520, which I can get for $600, but I have absolutely no brand loyalty. I've used the little brother, the 3150, in a build for a client and was quite impressed, and eva2000 seemed to get good results from the card over at i4memory, but if there's a better card available for about the same price I'd love to hear about it.
