What customers say about "Key Specs"
Western Digital My Book Desktop External HDD
  • It's really fast. It's faster than my old seagate barracuda internal drive connected through Sata III. It has an average sequential read and write of 160 MB/s.
  • This model (I got the 6TB size) is available in sizes up to 8TB. A pretty massive amount of storage on a USB drive!
  • This generation has 8TB, 6TB, 4TB and 3TB single drive models. Dual drive 12TB and 16TB models are available too.
  • I love WD external hard drives, these large capacity ones in particular. This is my first 6 TB one, I have 12 other ones that are only 3 TB and 4 TB, I've only used this one for a little over a week, but so far so good.
  • I installed the drive and one week later, the disc became corrupt, preventing me from copying any new files onto the drive.
  • Was disappointed compared to previous products, did not set up correctly, had to download software to make it work.
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"
Western Digital My Book Desktop External HDD
  • A file backup hard drive made for desktops. Not made to be highly portable as in the smaller, pocket-sized versions; it's made as a book-sized appliance that sits next to your desktop computer.
  • There is only one plus, which is its big size.
  • I was surprised at the size and heaviness of it and. i
  • Great value, nice size. I am using this to back up my backup of family videos.
  • It should be very clearly stated the number and size of the drives inside, horrible packaging description and a huge waste of time.
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"
Western Digital My Book Desktop External HDD
  • Easy to set up. I just plugged it in and it was automatically detected by windows with no problems.
  • It comes with a 4ft USB 3.0 cable (much nicer than the very short My Passport cables!)
  • The drive is faster than I expected. It took about 1 day to copy 5.14 TB to it via USB 3. Those were mostly music files 3MB to 60mb plus some videos.
  • The top half of the hard drive uses the shiny black paint that gets covered in fingerprints as soon as you touch it.
  • The hard drive has no indicator light that shows it is on or receiving power. You can only tell by listening or if it's detected by your device / OS.
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.
