Seagate Slim

Portable hard drives are great for carrying around data and for backups, but some “portable” hard drives aren’t always that portable. The Seagate Slim USB 3.0 portable hard drive, on the other hand, is amazingly thin and lightweight. But does it sacrifice performance for that svelte form factor?


  • Slim and lightweight
  • Very good USB 3.0 performance
  • Inexpensive
  • Compatible with Windows and Mac


  • Only available in 500GB capacity

The Seagate Slim’s enclosure is made out of plastic with a brushed finish on top. The USB 3.0 port is on the back and a thin, white activity LED is located in the back corner. That’s pretty much it for the Slim’s appearance, except of course, its extremely thin size.

Seagate chose to use the Momentus Thin drive inside the Slim portable drive. The Momentus Thin is a SATA 3.0Gb/s, 5400RPM drive. But its standout feature is the 7mm size. The Slim is only 9.6mm thick, so that means that the enclosure only adds 1.6mm to the drive, making the Slim an extremely thin external portable hard drive. It also only weighs 150g. To say that the Slim is small would be an understatement. You’d hardly notice its weight in your laptop bag.

The Seagate Slim is noticeably thinner than most portable hard drives, including Seagate’s own drives.

The Slim, like many of Seagate’s external hard drives, comes with NTFS drivers for Macs so that it can be used in Windows PCs and Macs interchangeably. It also comes with Seagate’s own Dashboard software, which can be used to back up files in real time and manage a few settings on the drive.

A portable hard drive as thin as the Slim has to have a catch, right? To see how its performance stacked up, I ran my usual benchmark utility, CrystalDiskMark. I was happy to see that its performance was not a handicap at all. It scored sequential transfer speeds of 113 MB/s read and 111 MB/s write.

The Slim’s usable storage space after formatting is 465GB, which was a good capacity a few years ago, but small by today’s standards. Ah, so that’s the catch––capacity. For the time being, the Slim has a limited capacity of 500GB, which depending on your needs, may not be a hindrance at all.

The Seagate Slim USB 3.0 portable hard drive is incredibly thin, lightweight, and performs very well over USB 3.0. Its only drawback is the somewhat small 500GB capacity. At just $70 online, the Seagate Slim is a terrific little drive if you’re looking for a portable hard drive that truly is portable.

Available from Amazon.com for about $70.

    I don’t know for sure since I haven’t tried to remove the drive from the enclosure. In my experience, the disks inside are not soldered to the controller board. My guess is that you can re-use the drive without any problems, but I’m not 100% certain.

    Could one remove the hdd from the case and use the disk in a computer as a main disk or is the converter soldered on the disk board ?
