Was curious if anyone was using these for hd video in esata setup, I plan on using tham to hold video both hdv and cinform on one drive them have two internal drives dedicated to other render and temp and one other internal OS drive, that way I can connect up to 4 external drives esata that house a lot of video to work on and render to internals, if you are using them are they fast enough or is there a problem? I already discovered they need to be reformatted in NTSF for larger files

and an esata pci-e1 card like thishttp://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3118921&CatId=1455

Yes, it works fine. I had the opportunity to test a system with 4 drives, SATA I raid, including a Blackmagic decklink card.
The footage was HDV 720, but the system had problems to playback real time in the timeline, even it has double Xeon 2.66 Gb processors and 3 Gb ram.
The good thing was editing in a stable EDL.
I suppose if you can work with SATA II it will give you better results.
