we used RAID at the shop I was at, anyone who uses it for backup is an
idiot.
The speed advantage went away when the drive's magnetic domains got
turned 90-degrees. With bits packed so tightly the data rates went way
up and the speed advantage of RAID went poof. I won't bother to argue
about RAID serving up bits faster. I will argue that it does not
matter. A modern drive is a fast as the job requires. It is not worth
any effort to go faster. The drive is not the bottleneck.
