I would go with cores (threads) rather than clock speed here. My home system is a 4-core AMD @ 1.8Ghz and performs well.
I wouldn't use drives that big and you should be aware of the overheads of RaidZ[x]. -marc On Thu, Feb 4, 2010 at 6:19 PM, Brian <broco...@vt.edu> wrote: > I am Starting to put together a home NAS server that will have the > following roles: > > (1) Store TV recordings from SageTV over either iSCSI or CIFS.
