WD’s My Passport 4TB mobile USB 3.0 drive lets you stuff a lot of data in your pocket without emptying it of cash. While not as fast with sequential transfers as the LaCie and Seagate drives we’ll be comparing it to, it’s certainly fast enough. And, at $115 on the street, it's considerably cheaper.
Design and specs
Because the 4TB drive housed inside is 15mm thick, the My Passport 4TB isn’t as thin as many lower-capacity units, measuring 0.85 inch from top to bottom. It’s approximately 4.25 inches long, 3.1 inches wide, and weighs around 8 ounces. The My Passport is also available in $60 1TB, $80 2TB, and $100 3TB capacities, with the 1TB version being about 0.2 inch thinner and 2 ounces lighter. All models come with a three-year warranty.
