I supposed you've forgotten linux has software RAID capability. I assure you, no RAID card within your budget will outperform the system processors even under load. While I generally recommend the use of hardware RAID, you don't have one of those in hand. So, unless you're going to go buy one *right now*, software RAID will do. (you *are* making backups, right?)
O.k., that's a useful recommendation, even if I do feel like you're yelling at me. :-)
Heh. That's not yelling. THIS IS YELLING YOU TWIT. *grin* If you check the archives (assuming it's in there), you'll see I was one of those in favor of hardware RAID. Software RAID is real easy to break. Hardware RAID, not so much -- you don't get direct access to the drives.
I have not setup software RAID in some years, but presumably it isn't hard?
It's not hard. And the modern tools (mdadm) make it even easier. The only problem is booting from RAID5. You'll need to create a boot partition that's RAID1 mirrored across all the drives in the array so you'll be able to boot if any drive fails. Then create the RAID5 rootfs. Rinse and repeat...
I'll dig up the raidtab.conf (whatever) from milkweed to show the madness. (attached)
