It's cheaper per GB for me to buy a couple of 320GB HD and RAID0 OR get SEAGATE ST3500630AS 500GB 7200.10 for a good price at least by Australian standards (USD217 delivered, 5yr warranty). Application: editing SD DVcam footage so speed not critical - which is recommended? I note the anomalies at barefeats re Seagate so bit wary of the 7200.10. I don't think reaching full 2tb or 3tb is an issue for me, althouth I will be using MacPro as PVR with a digial tuner. Mark.
