When I first got to this job we had a
major outage of multiple environments because they’d all been built on a
single RAID5 array that had a second disk fail while rebuilding the first disk
that had failed. RAID10 will survive double disk failure. If you must do
RAID5 make it into discreet sets so that the amount you lose in double-disk
failure is manageable.

Destaging going slow
From a storage perspective, I've got all disks in a Dell MD1000
enclosure configured in a single 15 disk RAID-5.
Don't ever do this. Jonathan has obviously gotten away with this (so far)
but using large drives (e.g. 1TB) in a 15-member RAID-5 set is just asking to
lose the array due to a double-disk failure.
I've done several recoveries for our Windows Server Team because they're
configured large RAID-5 sets and had double-disk failures.
