nVidia Raid vs Linux Software RAID



Im building a new server (I say server, it's just a glorified PC).

I don't know whether to go down the nVidia Raid route or Linux Software RAID route. I hear anything on chip like the nVidia stuff is just software raid anyhow and the Linux variant can be faster.

Any thoughts?

I have had an odd experience with nVidia RAID.

Configuring the Mirrored RAID, and Linux won't install. It needs a driver, but doesn't like any of the nvidia/ata/sata/ahci drivers I try and get it to load - says it can't find the disks. But if I leave the Mirror in place and switch off RAID in the Bios and use either AHCI or IDE, the array presents to Linux as one drive and Linux reports nVidia mapper.

I have to actually reenable RAID, and go into the RAID manager to remove the mirror, then my Fedora 9 installation sees sda and sdb!

Any thoughts on this too?
