WD My Passport 4TB 2016 Edition Portable External Hard Drive Review

WD My Passport 4TB Performance Benchmarks

CrystalDiskInfo is free benchmark that many people use to test storage drives with, but this test runs really quick and the results show the highest score of the five ‘burst’ tests for each performance metric tested. The problem is that the tests are so small and quick it rarely ever fills up a drives cache and is not a good look at real world performance on many external drives or SSDs that use TLC NAND Flash memory. We are including results for you to look at as you can use it at home to compare with to get an idea what the best case performance looks like on this drive.

WD My Passport 4TB CrystalDiskMark

We managed to hit 118.5 MB/s on the sequential read and 112.7 MB/s on the sequential write test, which is great considering the My Passport 4TB drive has a 5400 RPM hard drive inside.

WD My Passport 4TB ATTO Disk Benchmark

ATTO Disk Benchmark showed that we were getting up to 118 MB/s read and 113 MB/s write speeds as well, so it looks like the WD My Passport 4TB portable drive has some solid performance numbers.

WD My Passport 4TB Movie File Transfer

We wanted to do some real world file transfers, so we copied over an 8.1GB MKV Full-HD movie and found that we were getting around 104-110 MB/s on average. Solid performance, but as you can see sustained performance is a bit lower than the peak numbers shown in the ATTO and CrystalDiskMark benchmarks shown above.

WD My Passport 4TB Movie File Transfer

The last test we ran was to take 17 MKV full length 1080P movies that we had on a secondary data drive and move them all to the WD My Passport 4TB drive. These movies added up to just over 66GB and we found that it took us just 10 minutes and 50 seconds to move them all over and that averages out to being about 105 MB/s. Most importantly the write performance was high and pretty flat for the entire file transfer. Temperatures went from 30C at idle up to 38C on the My Passport 4TB, but that is respectable after writing nearly 70GB of data.

Let’s wrap this up!

    I think they ought to have future proofed this device with a USB Type-C port just like HERETIC said… I wouldn’t blame them though given that they’d still want to be in business in the nearest future. Anyway, I did an extensive review of the best Thunderbolt external hard drives 2017 has to offer on HDDClub. Here’s the link… you might want to check it out… https://hddclub.com/best-thunderbolt-external-hard-drive/

      why ? the hdd inside is slower than usb3, what would be the advantage to going to usb-c ? … what they need to do is bundle a usb-c to usb-3 micro-b cable (the one used on the hard disk)

  • Vinh

    Any plans of shucking the case to see what the internal HDD is, notably to see if the interface is USB or SATA? Thanks!

    • Nathan Kirsch

      The internals are the same as the WD My Passport Ultra, so it is USB.

    • RasterImage

      yeah usb soldered to the hdd controller board.


    The only missing feature that would have been nice was a USB 3.1 Type-C connector as that would help future-proof this drive.

    Yeah, and 99% of the world wont be able to use it

    • Nathan Kirsch

      That is not true. 99% of the devices in the world don’t have USB micro B either. Putting a USB-C connector on the device doesn’t change the fact the other end of the cable will be USB type-A still. It will just allow USB-C to USB-C cable use in the future. Many desktops, notebooks and smartphones are already moving over to USB-C ports. This would allow users to bring one cable on the road and as a road warrior myself I see that as being a positive.
