WD My Cloud Pro PR4100 40TB Review

Final Thoughts



WD has done a solid job with its My Cloud lineup. Over the years I have used a number of these units both for review and in my personal storage lineup. The PR4100 is by far the best I have seen a WD unit perform in a NAS environment. That said build quality is on par with the likes of Qnap, Thecus, Asustor and Synology. The enclosure has an equal mix of metal for durability and plastics to dampen noise and remove the bulky tray system that can at times amplify drive vibration. The combination of drive activity LEDs and the front panel display allow you to navigate to most basic options such as drive options and network connectivity.




The performance was able to max out our gigabit ethernet connection in sequential read and write and moving to workloads we found it to perform quite well in RAID 0 with a peak of 650 IOPs in Database. In RAID 5, we also had success with 118 MB/s in sequential read and 114 MB/s write. Workloads changed slightly with Web Server peaking at 440 IOPs.



The software platform used in the PR4100 is very user friendly and lends itself to the overall experience of this platform. For the most part if you know your way around a PC you can easily manage this platform via its well laid out labelled menu system. For power users, WD has kept features like iSCSI and the plethora of apps available. On the downside, I'm not sure why WD made the decision to not have RAID 6 capabilities on a four-bay platform.




In addition, pricing is a bit odd for this lineup and makes me think they set the MSRP when 10TB was first launched. Having not adjusted the price since then, you can currently pick up the Diskless PR4100 for $499 at many retailers. Add in four 10TB WD Red drives, at $318 each and you end up saving yourself a good bit of cash when compared to the 40TB PR4100 sent for review.
