What customers say about "Key Specs"
Seagate Expansion Portable 1TB External Hard Drive HDD
  • Great compact enclosures. I would suggest putting on some small rubber 'feet' on the base to lift it up and allow any heat to dissipate more freely.
  • I decided on this one purely because of the price point, the capacity, and the fact it was a Seagate!
  • This is my 4th Expansion 4 TB USB 3.0 Hard Drive but I have 7 more ranging between 1TB and 5TB capacity. The first I purchased in 2007 and have never looked back. All are going strong.
  • I bought the 2TB version. Usually, there's a tiny inaccuracy in the capacity. This version is actually 1.81 TB.
  • High-capacity HDDs are also a worry of course, because when they fail they take away a *lot* of data in one go, so these are only used for remote copies of data that is mirrored elsewhere on entirely different devices.
Seagate Expansion Plus 3TB External Desktop Hard Drive
  • Always feels cool, even during backup. Works great so far, without error or incident.
  • Very solid unit fine and sturdy construction.
  • USB 3.0 means faster download/upload speeds. No other power required.
  • Great little external hard drive i use to save my video files. Just plug in, and it works right away, just like a flash drive with a whole lot more space.
  • Overall really solid. Nice color and with some reasonable heft and weight, it doesn't feel cheap at all.

What customers say about "Size & Weight"
Seagate Expansion Portable 1TB External Hard Drive HDD
  • Opening the box, the unit is very compact, but functionally has done everything we’ve asked of it.
  • This device is so compact and reliable you can take it anywhere. Excellent value for money. Highly-recommended.
  • I bought it because it was compact but wish I'd gone bigger or another one now because it does feel like the manufacturers did the minimal they could.
  • I’ve never had any data crashes or losses, and the hard drive itself it small and compact for the amount of data it stores.
  • Runs smoothly and is nice and compact.
Seagate Expansion Plus 3TB External Desktop Hard Drive
  • Small size and slim design adds to portability, I bought a case as well for this just in case I dropped it as this is a sure way to ruin an external Hard Drive.
  • The small size takes up barely any desk space and is a simple drag-and-drop device.
  • Good size for the price. I've had mine for several years and it still works as good as when I bought it.
  • The size is portable and design is sleek.
  • Super nice size not too bulky or heavy. It is very easy to use.

What customers say about "Features"
Seagate Expansion Portable 1TB External Hard Drive HDD
  • USB3.0 made loading the drive up for the boss a breeze. This feature is wasted on him, but will definitely benefit me down the line when adding new photos.
  • It could be quieter, but it has good power saving features such as shutting down when not plugged into a computer.
  • Works fine. Took a while to arrive. I can't give it 5 stars as durability and longevity are key features and I have just received it.
  • Note, this drive does not feature a Kensington slot.
  • Not too sure about the boasted feature that it doesn't need a power supply.
Seagate Expansion Plus 3TB External Desktop Hard Drive
  • Installed my Seagate expansion hard drive to my computer, and it works perfect. I love the set up and its speed.
  • Speed wise, size, and use. So far this thing is fast, small and efficient for backing up files for on the go.
  • The enclosure has barely any holes for heat ventilation. The thing will start smelling like burnt plastic after 30 minutes.
  • Has a stupid plug and its starting to give me troubles.
  • It won't work on Windows 10. It stops every ten seconds.
