Probably more to do with better power lines, and especially better air
conditioning in the datacentre than the parts used. Oh, and left alone
and not fiddled with so much helps too :)

Avoid any motherboard based raid solution, none of them are any good. If
you've not got a real raid card then certainly if you're running linux
stick to software raid, it's a lot better. Linux software raid is
capable of booting with a disk failed assuming you've set up raid 1 on
the boot and root partitions.

As Jamie wrote, it's possible the bios may not boot correctly on a
partially failed disk.
