WD_BLACK SN850 2TB M.2 2280 PCIe Gen4 NVMe Gaming SSD with Heatsink - Works with PlayStation 5 up to 7000 MB/s read speed

Product Information

A new suite of features comes with the SN850X including Predictive Loading, Overhead Balancing and Adaptive Thermal Management 5. The most important competitors for the SN850 are other PCIe 4.0 M.2 SSDs. We have results for both the Samsung 980 PRO and the Silicon Power US70 based on the older Phison E16 controller. Our 980 PRO results are using newer firmware than our initial review of that drive, and we've added results for the 2TB model alongside our 1TB results. Western Digital SN850 Designed with an M.2 2280 slim, light, and compact form factor to easily slide into your gaming rig. Also of interest are two of the most premium SSDs from the PCIe 3.0 era: the 1.5TB Intel Optane SSD 905P and the Samsung 970 PRO. The 970 PRO was the last high-end consumer drive to use MLC NAND, which gave it a significant advantage on heavy, long-running storage workloads as compared with TLC SSDs that use SLC caching to provide improved peak performance. The 970 PRO is old enough that newer, faster TLC NAND is catching up even in tests where MLC used to be a major advantage—and of course the latest and greatest TLC drives with PCIe 4.0 have far higher peak performance. Intel Optane SSD 905P In the ATTO Disk benchmark, we see a similar result to the AJA system test. Both benchmark tests are based o sequential speeds. But ATTO Disk benchmark shows the maximum theoretical speed of a storage drive.

With up to 2TB 1 capacity, your PlayStation®5 console has the additional space to store up to 50 games 3 so you still have room for the next big title.

Thank you!

Western Digital doesn't give us detailed performance specifications the way Samsung does, but the basic specifications make it clear that this drive is aimed at the very top: sequential reads up to 7GB/s are pushing the limits of the PCIe 4.0 x4 interface that is still catching on in the consumer market, and random reads at 1M IOPS from a single M.2 drive were just a dream a year ago. Overall, these peak performance specs line up pretty well with the Samsung 980 PRO: Samsung quotes higher random write performance, and WD quotes slightly faster sequential writes.

Samsung also has an advantage when it comes to brand and reputation. For years, Samsung’s SSDs have been leading in the market. And it’s usually the choice of enthusiasts, gamers, and system builders. However, this time, WD was able to outperform Samsung’s top-of-the-line SSD. Although, not by a huge margin.Today’s A-list titles can take up 200GB 2 or more of storage. A range of capacities from 1TB to 4TB 2 means you get to keep more games at the ready and get into the action fast. Store and play more titles on a drive that’s officially tested and certified for your PS5™ console 4, so you can keep gaming without worrying about compatibility issues. Take advantage of irrational PCIe® Gen4 NVMe™ speeds up to 7000MB/s 2 read and 5300MB/s 2 write (1TB model) for a responsive and seamless gaming experience. Engineered and built with Western Digital 3D NAND to give you the reliability and endurance needed to sustain pro-level performance.
