Seagate Backup Plus 4 TB Portable 2.5 Inch External Hard Drive
  • As the other reviews have described, this HDD is about capacity and not useful for a standard NAS.
  • I have a few external drives, WD 2.5" and WD 3.5" cloud drive, but I think for size and capacity so far I like this quite a lot.
  • My only concern in advance is with such a large capacity drive there is a lot to lose when this goes faulty, consider this if the device is to be primary storage, if this is level 2/3 then happy days people !
  • This drive is large in capacity, slim in size.
  • Needed a high capacity reliable drive to back up 3 computers, unfortunately, this had the capacity but not the reliability.
Western Digital My Passport 4 TB Portable Hard Drive
  • This generation has 4TB, 3TB, 2TB, and 1TB models. The 500GB sizes in previous versions has been dropped.
  • High Capacity Available - Up to 4TB (The older model when released had up to 3TB capacity, up until a 6/28/16 release of a short lived 4TB model)
  • It's cute! Lol I love the color and size (definitely portable), and overall design - clean and neat. It's easy to format and use (thanks, Google) and can be password protected if desired.
  • 1TB weight went a bit up from 0.34 lbs to 0.37 lbs, 2TB ,3TB & 4 TB weight went a bit up too from 0.50 lbs to 0.54 lbs
  • Drive is not upgradeable nor swappable due to internal circuit board

What customers say about "Size & Weight"
Seagate Backup Plus 4 TB Portable 2.5 Inch External Hard Drive
  • takes a while due to the size of the disk, but has worked well so far (I've had to do this twice). Generally speaking, it's fast and reliable.
  • The drive is very small, about iPod Classic size and weight.
  • Don’t be fooled to think that this is a 7.5mm drive, its not. Size is nearer to 20mm but for an external device this simply doesn’t matter.
  • But this is true for any size, style or make of HDD, external or internal. Spend an extra £7 on a decent case would be my advice.
  • The size is great no bigger than a paperback book, two front facing USB PORTS for easy access, works quietly when engaged on backing up my RAW files
Western Digital My Passport 4 TB Portable Hard Drive
  • Great little portable external hard drive.
  • This WD 4 TB external portable drive is not the first I have purchased, which should speak for itself. I like the WD portable drives, being reliable, and not excessively priced.
  • It's very portable, and just a case of simply plugging it in and it's available for use with Windows 10 - no external power supply needed of course, so ideal for transporting around in my laptop bag.
  • This hard drive is perfect for using with my Raspberry PI as a portable video library.
  • I loved the blue of it, and I loved the portability it offered.

What customers say about "Features"
Seagate Backup Plus 4 TB Portable 2.5 Inch External Hard Drive
  • A nice feature is the front panel USB ports for quick connection of temporary items, my Ecig battery in particular.
  • Drive was detected straight away on Windows 10 and there are various software features loaded onto the drive should you wish to use them.
  • At the time of purchase it was one of the cheapest drives on the market for the storage and features.
  • Great product good backup features
  • Poor sealing(glue slightly comming of lid seal)
Western Digital My Passport 4 TB Portable Hard Drive
  • This drive works fine with Windows, Linux or Mac out of the box. With Linux or Mac it performs best when reformatted with a native file system for the respective operating system.
  • This drive is faster than the last generation. Up to 10% faster in benchmarks, but just noticeable in practical use.
  • The early drives came with 2yr warranties, but NOW come with 3 years. Yeah!
  • Rubber "feet" on underside keep it in place
  • USB 3.0 and USB 2.0 compatible
  • It comes with the same very short USB 3.0 cable as previous versions.
  • The redesign of the drive case is not a plus for me. Not much of a minus either as it's not why I selected this drive. The worst thing is going with pointy corners. From a handling perspective rounded corners are nicer.
