While it's in operation, the drive doesn’t make any obvious noise you’ll only hear it if you put your ear close to it. Only one cable was needed for the drive to work properly with our Lenovo Yoga 2 Pro, but a dual-head cable is also supplied in case your computer needs it. Even though there are two drives inside the Backup Plus Fast, it only requires one USB cable (and one port on your computer) to supply them with power, but Seagate provides a dual-head cable in the box as well, just in case your USB port doesn’t supply enough. For smaller files, the read rate was 161.9MBps and the write rate was 153.42MBps.Īs those tests show, you can definitely get great speed out of this Seagate drive when it’s connected via USB 3.0 to a computer with a fast drive, and it will come in most handy when moving large chunks of data such as video files. When we manually transferred large files, the Seagate recorded a read rate of 217.7MBps and a write rate of 204.54MBps. It’s not often we see write rates that are faster than read rates, but on RAID 0 drives, the two are often close. In CrystalDiskMark, the drive achieved a sequential read speed of 244.9 megabytes per second (MBps), and a write rate of 246.8MBps. We tested the drive on a Windows 8.1 hybrid laptop (a Lenovo IdeaPad Yoga 2 Pro) with a solid state drive (SSD), and we gauged its speed using CrystalDiskMark, as well as a range of manual file transfers to and from the laptop. They each have a spin speed of 5400rpm and 32MB cache. Specifically, Seagate told us that they are Spinpoint M9T drives from the company's Samsung HDD division.

The drives that reside on the inside of the case are slim, 2TB models, which provide a usable formatted capacity of 3.63TB. At 311g, it weighs noticeably more than a typical, single-drive portable hard disk. The only way you'll know there is something more to this drive than meets the eye is when you pick it up and feel it. It's a clean-looking, plain Jane drive with a single USB 3.0 interface on the back and an indicator light at the front.

It's a 2.5in unit that’s not overly thick (22mm), and there is nothing much about it to indicate that in fact two 2.5in drives reside within its housing. It looks almost the same as a 1TB portable drive from a couple of years ago. Physically, the Seagate Backup Plus Fast doesn't seem like much of a big deal. Seagate wants this drive to be used by photographers, videographers, and other mobile pros, but those of us with simpler plans will also benefit from its swift transfer speeds. It can do this thanks to a RAID 0 array running across two 2.5in drives, and, best of all, it only requires one USB cable for power. In Seagate's case, its Backup Plus Fast has a massive capacity of 4TB, and it aims to please PC users by providing faster than 200MBps transfers over USB 3.0. Portable hard drives with fantastical speed ratings have now hit the market from both WD and Seagate.
