The Western Digital My Passport Pro is a portable RAID array with a Thunderbolt port. Sadly, the My Passport Pro only has a Thunderbolt Port; there's no USB port, so you'll need a computer with a Thunderbolt port if you want to use it.

The Western Digital My Passport is a small, portable hard drive with a huge capacity - 2TB to be precise (that's 2000GB). No larger than a standard Passport drive with dimensions of 111x82x21mm, the unit is connected via a USB 3.0 cable that's also backwards-compatible with the more common USB 2.0.

These tiny My Passport drives from Western Digital earn our recommendation for a few reasons. They're extremely small and portable, they're capable of both USB 2.0 and 3.0 speeds, and priced between $90 and $180, they're quite affordable.

Extreme portability; No external power supplies or power cables required; You can set up password protection and hardware encryption

Fast enough for everyday use, but not the fastest; Not the cheapest, either

MacBook users, your portable hard drive has arrived. The Western Digital My Passport Studio ($220 list) is the Mac OS version of the WD My Passport Elite . It has the same compact case (albeit in a slightly more silver hue), protective port cover, and velvet-like drawstring bag.

I am constantly being asked about my red Passport. I use it at work every day and keep loads of different kinds of files on it, which are being updated all the time. I have had absolutely no problems with it at all and I've had it about a year now.

Lightweight; Docking station for super convenient hook-ups; Indicator shows available storage space; Software launches automatically; Optional password protection; Instruction manual is thorough and easy to understand

Slightly noisy when working hard

I am A big computer user and I do a lot of downloading of movies and music, my computer hard drive is 300 gb and I only had 20 gb left, it was enough to run my computer and keep it up to peak(ish) performance but that meant that I couldn't download anymore stuff.

Big capacity; small; convenient

can crash if handled to rough

Works Great price is outstanding

quick response when coping files

Transfer rates stayed the same with the installation of the SmartWare software, though the user experience decreased. If you don't install it, every time you connect the drive the software will mount and ask to be installed. This was extremely annoying.

With so many portable hard drives to choose from it's not easy for a new release to stand out from the crowd, but Western Digital's My Passport Studio 640GB succeeds admirably with an interesting feature that's more than just a gimmick.
