I concur with the use of 'soft' raid a server; hardware RAID can be a<br>
real pain to get working after a failure [which, isn't that kind the<br>
point?] while MD is really flexible and easy. Also CPU, etc... isn't<br>
really a host side limitation anymore; if you let the storage server<br>
focus on storage [and don't load on a bunch of other services] you can<br>
get blazing performance from a rather vanilla box.<br>
