This is a truly small drive, at least when we consider that we get up to 5TB capacity here. With its measurements of just 115mm by 80mm, it really isn’t big. The thickness is a little more than some other drives, but it isn’t a lot either with it being less than 21mm thin. Size matters for a portable drive and Seagate has managed to keep that low. The weight is equally low with just 265 grammes. Just put it in your pocket and take it where ever you go. Thanks to the bus-powered drive, you don’t need to carry a power supply either. That’s another big bonus for a portable drive.
