I'm deciding what drive I should get. I'll be using the drive for video editing and a bit of storage. The Big Disk has 16mb cache, where the d2 only has 8. - Would I notice a difference? I have two d2 drives, they're daisy chained, and I would like to add the new drive to the chain. - I gather The Big Disk would fit in the chain with no problems at all, right? I quite like the compacter d2 ones, would fit right in with the two I've got. A noticeable performance increase might make me reconsider.
