![]() ![]() This test uses SQL Server 2014 running on Windows Server 2012 R2 guest VMs and is stressed by Quest’s Benchmark Factory for Databases. While our Sysbench workloads tested previously saturated the platform in both storage I/O and capacity, the SQL test is looking for latency performance. From a system resource perspective, we configured each VM with 16 vCPUs, 64GB of DRAM and leveraged the LSI Logic SAS SCSI controller. We are reviewing the 4TB version of the WD_BLACK SN850X drive and will be comparing it to the following PCIe Gen4x4 drives:Įach SQL Server VM is configured with two vDisks: 100GB volume for boot and a 500GB volume for the database and log files. Under the sticker, you can see the DRAM and two NAND packs on the black PCB. The front side features the company branding, product name, capacity (at the top left) and all the supplemental information you need. The WD BLACK SN850X features a black, single-sided design with white and orange text–a look and feel in line with its predecessor. WD BLACK SN850X Specifications Available Capacities We will be looking at the 2TB model for this review. Warranty and Pricingīacked by a 5-year warranty, the WD BLACK SN850X goes for roughly $160 (1TB), $289 (2TB), and $699 (4TB). Overall the software is nice to have but won’t deliver “felt” performance to the end user. You can also see (at a glance) the drive’s overall health, interface speed, temperatures and capacity information. While SSD tuning software such as this often doesn’t show any noticeable real-world gains, it does allow users to perform firmware upgrades via the application (among other things), which is more functionality than many other companies provide. WD indicates that this is done by allowing the SN850X’s controller to detect incoming low queue depth, sequential workloads, claiming that it will help speed up in-game loading of scenes, levels and other areas. Game Mode 2.0 also features an advanced “read look ahead” algorithm, which predicts and pre-emptively caches what is next in the game. Users can improve the auto-launch detection by telling it to monitor specific folders. It will then turn Game Mode 2.0 off once you exit the game. ![]() When “auto” mode is turned on, your system will detect game launches and will turn gaming features on. ![]() Using the bundled software, this can be set to auto, on, or off. WD’s new Game Mode 2.0 offers PC performance-boosting features via its management software to help improve in-game loading speeds. WD also implemented new updates to improve thermal consistency and energy efficiency via smoothing out the thermal throttling step function. The SN850 also only offers up to 2TB in capacity, so the 4TB model is a nice addition to match the ever-growing game installation sizes. This is a fairly noticeable increase compared to the 2020 SN850 model’s 7GB/s read and 5.3GB/s write in sequential and 1 million IOPS in 4K random performance. The endurance rating is 600 TBW (total bytes written) for the 1TB, 1,200 TBW (2TB) and 2,400 TBW (4TB) with an MTTF rating of 1.75 million hours. The 1TB model is quoted with slightly lower numbers in sequential writes with 6.3GB/s, while random reads are a bit lower as well with 800,000 IOPS. In random 4K performance, the higher-capacity models are expected to reach up to 1.2 million IOPS read and 1.2 million IOPS write. The SN850X is specced with PCIe Gen4 performance, quoting up to 7.3GB/s read and 6.6GB/s write in sequential transfer speeds for the 2TB and 4TB model. The SN850X features increased performance, more “tuning” features via the new bundled Game Mode 2.0 software, and is equipped with a newer 20-82-20035-B1 controller.Īvailable in capacities ranging from 1TB to 4TB, the new PCIe Gen4 M.2 BLACK drive features an optional model with RGB lighting and a heatsink to help sustain peak performance when playing resource-intensive games. The WD BLACK SN850X is the company’s release from the consumer gaming NVMe SSD line and the direct successor to the very impressive SN850 from 2020. ![]()
