I own an i5 MacBook pro that I do a bit of HD video editing on. Up till now I've been storing the video on the internal HD, but I'm almost out of space (I only have 500GB). I want to get a bigger drive that will still work well with 720p editing in FCE, so I was looking at this enclosure with either this or this hard drive. Would these work all right for HD editing? Are there any other options I should be considering?
