As the disks get bigger, rebuild time also increases and the
performance of the disks don't increase linearly with their storage.
This means that when you are rebuilding a disk, the chances of one of
your other disks failing becomes significantly large. Most suggest
RAID6 these days as a minimum, mirroring and striping appears to be
the most popular.
