I think it's time to give the old server a little upgrade, as far as storage goes - a single 40 gig ATA100 laptop drive, held in with duct tape, just isn't cutting it any more.
(And I do mean old - it's an old Dell Dimension 2100, Coppermine Celeron 1100, 384 MiB RAM, an i810, and a genuine Windows Me license. Scary part is, it runs great, and it's actually become a game to see how many years I can get out of this thing, so far it's gotten 11 years of use (five of them being as my server), and other than the occasional HDD failure (I got it for free because of a dead Deathstar 60GXP, and I had an 8.4 gig Seagate drive crap out on me in it), it's been by far my most reliable computer ever.)
The server is currently running Ubuntu Server 10.04, in case this affects compatibility. I'll migrate it to 12.04 when it comes out.
So, it doesn't have SATA at all. I'd also like to go RAID 1 this time, and I'm thinking hardware RAID would be better simply to reduce CPU utilization.
What RAID-capable PCI (not PCIe) SATA card would you recommend? (Also, I'm wondering if I'm going to run into 48-bit LBA issues...)
