Your server might not, but many do. A friend of mine runs a server and
IO is the single biggest bottleneck on the box. He has 4 physical disks
with the data mirrored _and_ striped over them. So he has performance
and resilience.

Of course if the server is only an office server with some documents and
email then it's less of an issue perhaps. It's all about the usage.

Cheers,
Al.
