WD My Passport Ultra 1TB Portable Hard Drive Review

by Rob Williams on August 9, 2013 in Storage

For those who like a little extra when purchasing a portable drive, WD’s My Passport Ultra offers a compelling package. In addition to the inclusion of a soft pouch that helps keep the drive looking new, a robust backup solution is also included that’s easy-to-use and effective – and even sports the option of backing-up to the cloud, via Dropbox.

Page 3 – Performance Testing & Final Thoughts

For most of our performance-type content, we hold nothing back when explaining our methodologies and beliefs. But as this is simply an external storage review, we don’t feel there’s quite as important a need to do that. If you’ve read our other performance content, you already know how seriously we take our testing practices, as it’s obvious that coming up with an accurate end score for any benchmark is very important. In the case of flash drives, we repeat all tests at least twice to verify that our results are accurate.

  Techgage Storage Test System

For our real-world transfer tests, the source files are stored on our OS drive, which avails us a top-end read speed of 500MB/s+. Unless the USB device we’re testing is able to write in excess of that, there should be no bottleneck.

Drives are formatted to NTFS with 4K sector sizes.

Iometer 1.1.0rc1

To start things off, we’re using Iometer, a popular storage benchmarking application that’s as effective as it is customizable. It’s for both of those reasons that we choose to use it, and also thanks to the fact that it’s capable of outputting the results to both MB/s and IOPS (in/out operations per second). The latter is the value we focus on, as it’s become a standard for measuring performance in enterprise/IT environments.

Admittedly, running this test on most USB flash drives, is not entirely important given the typical manner in which they’re used, but it’s our goal to see where one excels over another when dealing with such an intensive test. IOPS performance would be very important if you were to install an OS on a flash drive, as long as the bandwidth throughput is also good.

  Database Workstation File Server
Iometer 1.1.0 Read Write Read Write Read Write
WD My Passport 2TB 57.593 29.225 76.850 19.095 77.779 19.376
WD My Passport Ultra 1TB 38.32 18.56 45.18 11.55 46.25 11.70
Results in IOPS; higher is better.

Interestingly, the Ultra falls behind the non-Ultra in IOPS testing. Again, this isn’t of major importance for an external drive, since an OS isn’t going to be installed to it, but this could impact transfers where hundreds or thousands of files are involved.

HD Tune Pro 5.0

One of the simplest methods for testing storage is with HD Tune, and as it’s able to give reliable and repeatable results, we like using it in our testing. Although the program offers a good range of testing methods, we use the basic test that gives us read speeds and also access latencies.

HD Tune Pro 5 Minimum Average Maximum Latency
WD My Passport 2TB 50.8 84.8 110.7 17.9ms
WD My Passport Ultra 1TB 56.0 91.0 118.8 16.4ms
Min/Avg/Max results in MB/s; higher is better. Latency results in ms; lower is better.

The Ultra didn’t fare well against the non-Ultra with Iometer, but things even out with HD Tune. In fact, the Ultra is the leader of the pack here, both in throughput and latency.

PCMark Vantage

One of the more popular storage benchmarks currently is Futuremark’s PCMark Vantage. Even though this is a suite designed to benchmark your entire machine, it’s HDD suite test is quite robust and is good at delivering scores that scale well with the storage device you are benchmarking. Almost all of the storage companies we deal with regularly recommend using it, so we do.

PCMark Vantage HDD Suite Score
WD My Passport 2TB 3632
WD My Passport Ultra 1TB 3832

PCMark backs HD Tune up here; the Ultra is just a bit faster overall, IOPS be damned.


Over the past few years, many storage companies have been jumping on the CrystalDiskMark bandwagon to help strut their product’s performance, and it’s easy to understand why. Compared to others, CrystalDiskMark delivers results that are much higher, and in some regards, they could be considered unrealistic given that real-world tests and even other synthetic benchmarks never seem to back up its claims. We include it for the sake of interest and because it is still a very thorough benchmark.

  Read Write
CrystalDiskMark 3 Seq. 512K 4K Seq. 512K 4K
WD My Passport 2TB 115.0 44.51 0.567 107.6 70.23 1.759
WD My Passport Ultra 1TB 121.0 43.92 0.566 118.7 62.98 1.441
Results in MB/s; higher is better.

Once again, more love for the Ultra drive. The non-Ultra came ahead in just two tests; this is about as random as random gets… there’s just no logic or guessing where either of these drives is going to excel.


While CrystalDiskMark does well to show the absolute top-end value of a storage device, ATTO doesn’t fall too far behind, if at all. Its test uses a wide-range of cluster sizes, for both read and write, but we only note 4KB, 64KB and 1024KB of the former. For those interested, we use a queue depth value of 10 for testing.

ATTO 4KB 64KB 1024KB
WD My Passport 2TB 54.46 108.91 104.86
WD My Passport Ultra 1TB 44.55 115.66 114.97
Results in MB/s; higher is better.

The Ultra is a tad slower where 4K writes are concerned, but 64KB and up are improved. This is useful if the drive is actually formatted as 64KB, which would assume mostly large files are being stored (and by large, I mean 64KB and higher, as a 1KB file on a 64KB formatted drive will still use 64KB).


For real-world testing, we use a set of files and folders for the sake of measuring transfer speeds, and also convert images and music on the storage device to see just how well it fares for large intensive operations. For the transfer speeds, we use both 4GB and 16GB files and folders, and for the former, we also perform copy tests, which refers to copying the file or folder on the storage device.

  4GB File 4GB File Copy 4GB Folder 4GB Folder Copy 16GB File 16GB Folder
WD My Passport 2TB 37.547 106.73 80.584 142.341 144.29 325.429
WD My Passport Ultra 1TB 37.08 138.82 57.77 235.32 97.12 102.68
Results in seconds; lower is better.

Above, I said some of the results are as random as random gets, but our real-world testing takes things to the next level. While the Ultra proved to be slower IOPS-wise of these two drives, our 16GB folder copy, which contains about 16,000 files, proves that Iometer is good from a synthetic standpoint only.

Overall, both drives swapped their leads back and forth, so there’s no declaring one a winner. The performance we do see is good, and that’s all that matters – it’d be a worry if one of them happened to be really slow in a given transfer. The 16GB non-Ultra result is a bit stark, but 5 minutes to copy 16K files isn’t that bad.

Final Thoughts

With all we’ve learned about WD’s My Passport Ultra over these three pages, do we have a winner? Absolutely. WD offers a great overall package with its Ultra, what with the robust backup software and included pouch. Looking at other portable options on the market, I can honestly say that WD is currently offering one of the best looking options as well.

The Ultra 1TB can be had for about $100 online (2TB is $160), which is $10 above the non-Ultra. The differences, as discussed earlier, is that the Ultra includes the soft pouch, the ability to use Dropbox for backing-up, and also the ability to backup to other (even non-WD) drives. If none of that matters to you, then the non-Ultra would be a better choice.

At $100, there are a couple of cheaper models out there, some even $20 cheaper. I can’t speak to their quality, however, and neither include backup software (or the pouch and other perks). Again, if the aforementioned perks don’t matter to you, there are lesser-expensive options that might be worth considering.

WD My Passport Ultra 01

When I took a look at the My Passport last summer, I complained that the backup software, SmartWare, was a bit too clunky for my liking. This time around, despite it being the same exact software, I found myself enjoying it more. Either I was a bit impatient last time, or it just takes a little time to grow on you. Either way, it might be a bit clunky, but it becomes easy-to-use very quickly, and it works very well. The ability to include Dropbox as a backup source is great as well, although it’d be way better if WD added Google Drive and Microsoft SkyDrive to the list (not that a list is a single option). It’s not as though WD is giving us free Dropbox space here, so I don’t understand the exclusivity.

As we saw in our performance reports, the Ultra performs just about as we’d expect a 5,400 RPM mobile hard drive to. It’s not amazing performance, but it’s hardly lacking, either. 16,000 files (16GB) in under 2 minutes seems pretty good to me. And of course, along with all of this, you also get a pouch, perfect for those who like to keep their drives as protected from scratches as possible.

WD offers a great product with the My Passport Ultra, and while some things could be a bit improved, the biggest hit comes down to the fact that only a single cloud solution is offered. Hopefully that will be remedied in the future. But for what it offers now, and the fact that it does everything it does offer extremely well, the My Passport Ultra earns our Editor’s Choice award.
