Can anyone recommend an appropriate RAID card for use under Linux (Ubuntu)? I have three Western Digital SATA drives, and would like to setup either RAID-1 or RAID-5. Software RAID has been very flakey and unreliable for me (e.g. it doesn't seem to mirror the boot partition).
Unfortunately, most RAID cards I've seen online don't mention any Linux driver support. Would most cards work in Linux, or do I have to look at a select few that explicitly support Linux?
