Final Thoughts




A few years back, I took a look at one of the very first Thunderbolt solutions to hit the market, the My Book Thunderbolt Duo from Western Digital. At that point, I found that unit had a decent amount of features and respectable performance that hovered around 250 MB/s. With time, technology evolved and so did the My Book. With this new Pro model, Western Digital has revamped their Thunderbolt offerings with performance nearly double of what I found all those years ago.



The build quality has undergone quite the facelift as well. Whereas the original Thunderbolt enabled My Book consisted of a rounded plastic shell this new solution speaks for durability with its metal exterior and steel chassis. While the front bezel of this unit is still plastic, and glossy at that, I was pleased to see how well the drive trays slid into the enclosure. The blue LEDs of the enclosure carry soft lighting, so they aren't too bright and easily accessible USB 3.0 port make syncing data very simple.


The performance of the My Book Pro is solid for a hard drive driven solution. In our testing with Black Magic Design, our RAID 0 array touched 400 MB/s read and write while RAID 1 reached 183 MB/s read and 214 MB/s write. Similar results with AJA System Test where RAID 0 produced 376 MB/s read and 366 MB/s write with the 720p workload. 1080p and 4K workloads were able to produce near 316 MB/s and 256 MB/s read while write performance hovered around the 200 MB/s mark.


One downfall of this solution or quirk rather is you cannot access the full suite of options in the WD Drive Utilities when connected via Thunderbolt. Instead, you have to keep your USB 3.0 handy to change RAID modes or even view detailed information on your drives.


Overall, the WD My Book Pro is still an extremely flexible storage solution for prosumers and brings intense capacity and solid performance to creative professionals on both Windows and OS X platforms. Western Digital backs this up with three-year warranty, while the MSRP comes in at $999.99 for the 12TB solution seen here today.
