Summary: I read the reviews and opted for a drive that worked(was formatted for Mac) right out of the box. Worth the extra money for me, I don't have to worry about my 3 year old mac, losing all my photos, peace of mind....
Summary: This drive is good enough. Works well with my Mac Air. I like: The USB3 is valuable. First thing I did when I got it was to transfer 40GB of photos and videos from 10 years from my Mac to the My Passport. Took maybe 5? minutes. I then made the same file/set transfer to another USB2 drive. Took 30?
Summary: This is a fantastic hard drive for photo or video editors that work on the road. It's very small and very light. Its USB 3.0 speeds are very good, making it a great choice for a Photoshop or Final Cut scratch disc. It's smaller and cheaper than portable Thunderbolt drives.
Summary: I have been using the for my Macbook Pro and Macbook Air. It was a very slick drive, enclosed with brushed aluminium case and supports Firewire 800 and USB 2.0 connections. Now, I have the WD My Passport for Mac which looked very similar to the WD My Passport Studio.
