A friend of mine has a massive RAID 5 using RAIDframe, something like
3x1TB and 3x1.5TB. It works fine but it needs a very long time to
re-build the parity after an ungraceful shutdown. IIRC it takes over
24 hours.

If long re-builds are a problem in your case you probably want a
hardware RAID controller. Alternatively you could wait for the
result of RAIDframe GSoC project(*).

        Kind regards
