WD makes a range of portable storage devices under the My Passport brand. GadgetGuy reviewed the My Passport Ultra 4TB and the My Passport SSD.

Portable storage seems to be a battle between capacity and speed. SSD provides speed and capacity to 1TB. Ultra uses a spinning hard disk and capacity up to 4TB.

In a few years’ time, SSD will be at cost parity per GB with hard disks – there will be no more need to compromise.

Review WD My Passport SSD (Global website  here)

This is a diminutive sized SSD at 90 x 45 x 10mm x 39g (without cable). It is USB-C 3.1 Gen 2 capable which means data transfer speeds of up to 10Gb/s or 1250MB/s. Of course, to achieve to achieve that you need a computer with a similar UBS-C spec or Thunderbolt 3.

Brief specs

  • Mac (requires reformatting) and Windows capable
  • Backward compatible with USB 2.0 (maximum 480MB/s)
  • Will withstand a drop of 1.98m (important for portable devices).
  • WD Backup software will back to a hard drive or Dropbox cloud service account.
  • Compatible with Apple Time Machine (requires reformatting). It has a three-year warranty.
  • WD Discovery software provided
  • Can use password protection
  • 256-bit AES Hardware Encryption with WD Security software

The test unit capacity was 512GB, and we used a Microsoft Surface Pro 4. Cable connection was via a USB-A 3.0 to USB-C adaptor (supplied). We would expect faster results on a USB-C 3.1 Gen 2 device. If possible, we will update these figures with a Thunderbolt 3 device.

Crystal Disk Info identified it as SanDisk SATA 600 with 477GB usable space.

The figures below are very respectable for a portable device. Interestingly reads from the disk are usually faster than writes to it.

My PassportWe compared it to a 1TB Samsung T3 SATA 600 (now superseded by the T5). This is the fastest (and most expensive) portable SSD. While the Samsung figures blow the WD out of the water for raw speed remember that you are using this as a backup device and speed needs only to be respectable for typical use. If you were backing up large GB files, then speed becomes important.



  • Far better than a USB Flash drive
  • Comes with USB-C cable and USB-A adaptor
  • Nice looks
  • Light and small
  • Fit for purpose
  • Lots of WD software


  • Slower than a Samsung T3
  • No IP rating – keep away from pool and toilets

GadgetGuy’s take – My Passport SSD it a great portable

A great little backup device with capacities up to 1TB.
