This particular model is what’s being called the “older model” which is only slightly bigger than the newer version and this model has the perforated top and bottom cover rather than the newer smooth surface.

This makes it easier to transport and also takes up less room on my desk. The format of this unit is somewhat different than most portable hard drives in that it is more square. For the money, it’s hard to find another drive to match it. There is a reason this is rated a #1 Best Seller on. I am a long time fan of WD products and the 1TB WD My Passport Ultra is no exception.
