Summary: Has adequate speed to process HD video with Imovie, and setting it in a RAID has increased speed. I will probably get the 64 mb cache model next for the speed. I use it mostly for video and audio storage and processing.
Pros: Fast Connectivity, Quiet, Reliable, Versatile
Summary: I purchased this hard drive to backup a rather large itunes library. The first drive began to have problems almost immediately. Hard Disk Sentinel indicated that the drive had a large "spin retry count" so I returned it and got a replacement. The replacement worked well for a while but about a week later while backing up my computer Both Hard Disk Sentinel and Windows 7 warned me that drive failure was imminent due to problems with the servo motor.
Summary: If using outside of Raid Array I suggest partitioning it into roughly 450 to 500 Gig partitions to make it easier to work with. You wont lose any storage space and for purposes of defragging, virus scanning and access it makes the most sense. Use of Quick Format option can make set-up a breeze. Always have more then one backup of files as putting all your eggs into one basket is unwise for obvious reasons.
Pros: Easy to set- up, Fast Connectivity, Price per Gig, Quiet, Versatile
Summary: Bought 2 of these drives. 1 arrived dead. The other works fine. Both heat up quite a bit. I guess if the drive is going to fail it's best it fails right away rather than after you load your data on it. Waiting on replacement. I'm sure Buy.com will make good on it.
