Compared to the 2TB version of the same line, My Passport Pro 4TB is nearly double the thickness and weighs 720 grams. This is also consistent with the fact that the product uses a 2.5-inch, thick 15mm while the Passport Pro 2TB uses a 9.5mm hard drive.
Highlights in product design are the use of Thunderbolt communication with data transfer rates of 10 Gb / sec, twice as fast as USB 3.0 and about 12 times the FireWire 800 interface. My Passport Pro also supports modes such as RAID 0 (striping) to improve data access speed of the hard drive, mirroring to safely protect important user data while JBOD (just A bunch of disk allows you to combine and make the most of both hard drives.
Unfortunately, the design is My Passport Pro for only Mac users, compatible with Apple Time Machine for simple and fast backup. The add-on utility WD Drive Utilities supports RAID configuration, hard drive status checking, and allows thorough erasure of data stored on the device.

Performance evaluation
Test Lab conducted data transfer testing between My Passport Pro 4TB and MacBook Pro Retina ME295 through Thunderbolt interface on both RAID 0 and 1 hard drive configurations. The testing tools include AJA System Test, Blackmagic Disk Speed Test and practice measurements with 10GB of mixed sample data of various formats.
The results below show that when running with two RAID 0 hard drives, the data rate of My Passport Pro 4TB is quite high, with read speeds nearly reaching the manufacturer’s declared value (233 MB /paper).
Specifically, Test Lab records speeds of 207.1 MB / sec and 204 MB / sec through Disk Speed Test. The results of the AJA System Test also differ slightly from the read speed of 208.3 MB / sec and write up to 206.5 MB / sec.
On the actual speed test, copying 10GB of sample data from a variety of formats, including HD movies, lossless music, source install applications, and text files between your MacBook and My Passport Pro. Through the Thunderbolt interface. The test configuration took 59 seconds to finish copying data to an external storage device with an average write speed of 173.6 MB / sec. In contrast to the read task with the 10GB of mixed data on, the WD hard drive model takes only 55 seconds, average read speed 186.2 MB / sec.
Also in the real test with a single 10GB file, My Passport Pro read and write speeds increased significantly with improvements of 13.5% and 7.8%, respectively, read is 200.8 MB / sec and write is 196.9 MB / sec.
In the basic RAID 1 form, data security is a top concern, so it’s no surprise that My Passport Pro’s read and write speed is only half that of a RAID configuration. Specifically, the speed of reading and writing data through the Disk Speed Test tool is 103.4 MB / sec and 100.1 MB / sec, respectively, and the AJA System Test is 103.5 MB / sec with read speed. and write speed is 102.6 MB / sec.
Overview
Large storage capacity, high data rate and support for RAID 0, 1 and JBOD configurations as needed, WD My Passport Pro 4TB is suitable for users in the design, creating or editing movies needs to work with large amounts of data.
