What!?  1TB?  At home?  Have you bought HMVs entire stock and converted
it all to MP3 format or something?  How the heck have you stumped up a
terabyte at home?

You win the big data award, btw!  :-)

I can't find a reference to SATA raid drives anywhere... I've tended
towards seagate and can't find anything on their site about sata raid
drives??? Got any urls that I can look at?

Basically this project is one that is sorely needed but may not get
past the requisition stage if its too pricey.  Not directly linked to
sales success, ergo, not important...  Hence I was looking at SATA
rather than SCSI, but maybe I'm fooling myself a bit.  Possibly
investing in a decent enclosure and some good drives will save me
headaches down the road...

On the other hand maybe getting a decent drive enclosure will be enough
to reliably house a set of SATA drives?

Why's that then?  Having a full drive backup is quite an attractive idea
I think.  Or are you acking the LVM snapshot stuff?
