I too have been following this with interest. Being paranoid, I mirror the
database twice - once in hardware and again in software, but I appreciate
this is a luxury not available to most.
I'm sorry but I fail to see the logic in not using battery-backed cache in
the RAID controller. If

Thank you all for your comments. This has been an interesting discussion
to follow.
My original incentive to change was performance. We're in a database I/O
bottleneck situation, and hardware mirroring/striping should definitely
help. I'm in the process of changing to it right now, and I'll
