Anyone tried built-in raid in P55/Q57 chipset?

[aaron d]

I researched this recently as I have the desire to mirror some data reliably
and have found that, while "fake" RAID and software RAID perform about the
same when they are setup and working, there really is NO reason to use
"fake" RAID.

So basically, if you are looking for the absolute best in throughput,
support and reliability, get a real RAID card. If you are just concerned
with getting a reliable mirroring set-up (like myself) that you can move to
another box as you swap/upgrade, or are looking for marginally better
throughput without plunking down bucks for a proper controller, use linux
software raid, NOT fake raid.
