Even that's not necessarily true. For example, having a battery backed
write cache on your RAID controller can improve your disk performance
by an order of magnitude (depending on workload, naturally).

There are pros and cons to both approaches, though. It's just a case of
weighing them up and deciding which is best for any given situation.
