MB/s = 1 million bytes per second. Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and other factors. DirectStorage sure sounds as that there will be some improvement, albeit assuming you aren't running GPU at full load already, as DirectStorage apparently works mainly at the premise of taking some workload from the CPU and giving it to the GPU, such as to decompress files that get loaded in when walking to a new area in an open-world game. And for current-gen gaming, even slower NVMe SSDs sure are plenty fast. Crucial P5P and Samsung 980 Pro (after the discounts) are great value drives. That is what I can conclude from this. These changes make perfect sense. The 500GB didn’t perform as well as the larger capacities, and the demand for larger sizes is one WD couldn’t continue to ignore.

WD improved performance in sequential read workloads, with a maximum of 7.3GBps from 7.0GBps, and sequential writes improved from up to 5.3GBps to 6.6GBps. Performance in random workloads has also improved significantly, up from a maximum of 1M / 720,000 read and write, respectively, to 1.2M / 1.1M. The controller appears to be an updated version of the one found on the SN850. It’s still eight-channel but is paired with faster flash and improved firmware. WD tends to have excellent firmware, perhaps best exemplified in the SN770. The SN850 also did relatively well in our Phison I/O+ firmware preview, performing quite consistently. The Game Mode 2.0 optimizations should make the SN850X even better there, although it’s still too early to make judgments on game applicability. abufrejoval - Thursday, March 18, 2021 - link Somehow I think that I'll never be able to recover in the faster response times of this drive the time it would take me to swap it against the 980 Pro I currently have in my Ryzen 5800X workstation... On the mixed sequential IO test, the SN850's performance is better than any of the 1TB drives, and almost as fast as the 2TB 980 PRO. It's still not quite as efficient as the 980 PRO and during this test it averages about 6.6W, which is definitely getting up to where a heatsink would be of use (for similarly long-running workloads).

The Western Digital WD Black SN850 Review: A Very Fast PCIe 4 The Western Digital WD Black SN850 Review: A Very Fast PCIe 4

We report three idle power measurements. Active idle is representative of a typical desktop, where none of the advanced PCIe link or NVMe power saving features are enabled and the drive is immediately ready to process new commands. Our Desktop Idle number represents what can usually be expected from a desktop system that is configured to enable SATA link power management, PCIe ASPM and NVMe APST, but where the lowest PCIe L1.2 link power states are not available. The Laptop Idle number represents the maximum power savings possible with all the NVMe and PCIe power management features in use—usually the default for a battery-powered system but rarely achievable on a desktop even after changing BIOS and OS settings. Since we don't have a way to enable SATA DevSleep on any of our testbeds, SATA drives are omitted from the Laptop Idle charts. 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.

billion bytes and 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment. SN850 with heatsink is intended for Desktop PCs and PlayStation™ 5 (PS5 system software version 21.02-04.00.00 or higher required). For details on our mixed IO tests, please see the overview of our 2021 Consumer SSD Benchmark Suite. One is a new Game Mode 2.0 capability, a flexible software control that enables the drive to be specifically tailored for enhanced read speeds. More on this below. Performance & Benchmarks 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.
