Not to try to drag this conversation even more off-topic than it already
is, but I'm finding this talk about the potential of 3ware cards or
drives going out and losing big important RAID devices and etc really
pretty funny, since IMNSHO, anyone trying to build production-level,
mission-critical RAID volumes off of cheap-o IDE drives and what I
consider a pretty nice, but really pretty low-level IDE RAID card is
just asking for problems to begin with.
The 3ware cards are nice if you have a bunch of IDE disks lying around
and need space and like to be able to do hardware RAID, but if I were
building a mission-critical datastore, I'd definitely be using high-end
SCSI drives and a RAID controller I was *damn sure* was as bulletproof
as I could get.
So this discussion is making me chuckle. :)
