I'm shortly going to be setting up a Linux software RAID 5 array using

not its "hardware" fakeraid).

How long are you expecting a rebuild to take in the event of a
disk failure? You may well be better off creating a bunch of smaller
5 disk RAID5 arrays rather than one big one.

An aside - we've just taken delivery of an EMC CX300 storage system.
We've configured a RAID 5 array with 15 146GB Fibre channel disks and
a hot spare. We've just pulled one of the disks from the array and
are watching the rebuild take place. I'll let you know how long it
takes!
