Final Thoughts



Sequencers, tiered caching, geared ECC - Western Digital's NVMe controller is truly a force to be reckoned with. As we saw throughout our testing, the built from the ground up WD controller ushers in the end of Samsung's reign as the undisputed king of flash-based enthusiast storage. With no less than six new lab records delivered by Western Digital's latest and greatest, it is safe to say that WD is now the leading performance broker when it comes to consumer TLC flash-based storage.




We are stunned and amazed that any TLC SSD can challenge the best MLC has given us to this point. Based on performance alone, we are compelled to consider that the WD Black and Extreme Pro may actually be the best performing flash-based consumer SSDs ever. They were able to surpass the mighty Samsung 960 Pro's performance more often than not. Now, if we take into consideration performance and price point, there is no question that the WD offerings are in fact the best value for an enthusiast grade SSD on the market today.



Of all the testing we did, we are most impressed with the way the 1TB WD Black and Extreme Pro delivered far and away the best PCMark 8 extended recovery performance we've seen from any flash-based SSD. It's leaps and bounds better than Samsung's MLC powered 960 Pro 2TB. This means that shortly after running extended heavy workloads, there is no flash-based SSD that will deliver better moderate consumer type workload performance.


Additionally, the WD Black and Extreme Pro are far and away the best performing consumer SSDs when writing data. Whether it be random or sequential data, the WD offerings currently have no equal. The only place where we see room for improvement would be read performance at low queue depths. We also would like WD to get on board with a proprietary NVMe driver. Samsung and Intel both offer a performance enhancing NVMe driver which boosts random performance significantly.


64-layer TLC flash has, this year, become the dominant type of flash in both the consumer and enterprise space. In-fact, neither WD or Toshiba are planning to produce MLC flash going forward. We didn't think that TLC would be able to completely displace MLC, but it's looking more inevitable with each passing day. In a world full of TLC flash, we are confident in saying that as it stands today, the WD Black and the Extreme Pro are the best of the best.




Because TweakTown tests SSDs with the drive running as our system (OS) disk we are in a relatively unique position to comment on what matters most - actual user experience. As you can imagine, the user experience delivered by the WD Black and Extreme Pro is as good as it gets for flash-based SSDs. It's blow your hair back user experience that will have you congratulating yourself for choosing Western Digital's finest.


Needless to say, the Western Digital Black NVMe and SanDisk Extreme Pro NVMe SSDs are 100% TweakTown recommended.
