Anyone using these? Are they as quiet as claimed? Are they fast enough for DV editing? I'm looking to stick x4 160GB discs in a RAID media/general file server now, with a view to being able to try my hand at video editing in due course. The server is a rackmount dual PIII 933 Acorp i815EPD with embedded Promise Fasttrack 100 Controller, which, with the exception of the temporary HDD's I'm using is, so far, virtually silent and I would like to keep it that way. The Maxtor DM9's would be great for the large capacity but a friend has one in a PC and it's noisy in comparison to the Seagate Barracuda V I have in the HCPC. Any thoughts, guys?
