I've used ReadyNAS appliances at home for almost 10 years. The current
product line is made up of low-power Atoms. I'm running a RAID5 across
4 500G enterprise SATA drives (that should indicate how old this unit
is pretty well...) I have a wired network primarily in the rack in the

In this case the smallest config is a file server and a terminal/cpu

Ken's file server is standallone and has special user space.

Can you clarify which file server, specifically, you're comparing for each of
