Random read performance is similar throughout the transfer sizes for all three drive configurations.
What you see in the charts below is speed in megabytes per second (y-axis) at various transfer sizes in kilobytes and megabytes (x-axis). All tests were run five times and the results were averaged. We used Intech’s QuickBench to gauge random and sequential read and write performance.
4TB MY PASSPORT XBOX ONE PRO
The installer for the app is included on the preconfigured volume, but you can also download it from the company’s website.Īlthough we used the WD My Passport Pro with a variety of Macs during our testing period, the following benchmarks were conducted on a 2011 15-inch MacBook Pro running OS X 10.9.2.
4TB MY PASSPORT XBOX ONE INSTALL
But if you’d like to change the drive’s RAID configuration or access Western Digital’s diagnostic tools, you’ll need to install the WD Drive Utilities app. For users seeking maximum performance on a Mac, no further configuration is required. The WD My Passport Pro ships configured as a single 4TB RAID 0 HFS+ volume. You can still utilize multiple Thunderbolt devices via a single port, but you’ll need to place the Passport Pro at the end of the chain.
4TB MY PASSPORT XBOX ONE PORTABLE
Like most portable Thunderbolt drives, the WD My Passport Pro has only a single Thunderbolt connection there’s no second port to enable daisy chaining. Just connect it to a compatible Mac and you’re right at home with your own OS and data. This capability means that the WD My Passport Pro can act as a handy portable workstation, with one drive serving as a custom installation of OS X and the other for data storage and backup. In each case, OS X installed and booted with no problems. We installed OS X Mavericks to both a single one of the Passport’s drives as well as to a RAID 0 volume comprising both drives. This requires the use of the company’s WD Drive Utility in order to manage RAID settings, but it eliminates the overhead of software RAID configured via OS X’s Disk Utility. Unlike many multi-drive external devices, the WD My Passport Pro utilizes onboard hardware RAID.
As you’ll see in the benchmark section below, we achieved maximum sequential speeds just above this figure. In a RAID 0 configuration, Western Digital advertises speeds of up to about 230 MB/s. While we can’t be sure about the 2TB model, our 4TB model contained two 2.0TB WD20NPVX “Green” drives, which are currently selling at a street price of about $150 each.Ĭonfiguration options for the WD My Passport Pro include RAID 1, RAID 0, and JBOD (individual drives). Western Digital currently has no plans to introduce a model with SSDs, and a company spokesperson explained to us that the capacity and cost savings of HDDs outweighed the speed advantages of SSDs. These are mechanical hard disk drives (HDDs) and not faster and lighter solid state drives (SSDs). Technical SpecificationsĪs mentioned above, both WD My Passport Pro models contain two 2.5-inch drives. It’s not a deal breaker, but it’s definitely something to consider, especially if you plan to use the WD My Passport Pro in a more permanent desktop setup.
Although most users will likely have the drive placed within about a foot of their laptop, drives without integrated cables give users the option to attach virtually any cable length, allowing for far more placement options. Placement flexibility is also an issue with the integrated cable.
