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 Backup Plus Fast 4TB Portable External Hard Drive USB 3.0

  • It's fast and work great. This is the best external hard drive I have ever had.

  • A high quality, high capacity, portable external hard drive useful for when I travel and need access to more docs.

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 Backup Plus Fast 4TB Portable External Hard Drive USB 3.0
  • The drive can fit into a medium size jacket pocket, so it is somewhat portable.
  • For the memory capacity and overall size and weight you just cannot complain about this product.
  • This is a lot smaller than I was expecting in physical size, but it works great.
  • It is nice having these small high capacity drives that are only powered via USB.
  • Very compact for the size, so far holding up well.

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 Backup Plus Fast 4TB Portable External Hard Drive USB 3.0
  • This drive works by connecting included cable to USB port and responds quickly when selected for use.
  • It's size and weight is unbeatable. Never had any problem using this drive on my different devices.
  • Not so fat as I thought. Overall I satisfied with design, speed and ofcourse size. Speed is good getting around 80-120 on USB 3.0 and in-built back up software needs lot of improvements.
  • While it is great to have this size in a portable, the speed leaves much to be desired, even with the double usb boost.
  • Lags like crazy even with a 480p video and is virtually unintelligible for 720p or 1080i.
