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.
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.
We compared it to a 1TB Samsung T3 SATA 600 (now superseded by the T5).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
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.
256GB – $196
512GB – $229
1TB – $624
Look online for bargains. There is no issue buying a parallel import of this product.
The test unit was a 4TB – capacities range from 1TB
Crystal Disk Info says it is a WD SATA 600, 5400RPM hard disk. It comes with a USB-A 3.0 to USB 3.0 micro-B 10 pin connector (it has a micro-USB beside a power connector).
No matter how fast the USB 3.0 interface is, it will be limited by the read/write speeds of the hard disk.
While Crystal Disk Mark shows a reasonable (to be expected from a hard disk) internal read and write speed the aging USB-A to micro-B interface really lets it down for large file transfers giving speeds from .5MB/s to 1MB/s.
GadgetGuy’s take. My Passport Ultra – slow but fine for external backup
99% of review don’t bother to run data transfer tests like Crystal DiskMark. While no test is a perfect recreation of real world use, it is at least a benchmark.
Looking at the test results for larger files prompted me to test an older My Passport Ultra 2TB. It also used the micro-B connector. The test results were similar. Fine read/write speeds but lousy for larger files. Still I have been using it for years and found it perfectly good for backup.
So, we have answered the conundrum. SSD for speed/durability and hard disk for capacity.
