it highly depends on the hardware raid. The true hardware RAID with
hotspare, hotswap etc. support and with proper drivers (so you won't have to
boot into its bios to reconfigure it) will be much more reliable.

it highly depends on the hardware raid. The true hardware RAID with XOR
counting and mirroring support will be much faster.
