![]() ![]() At the same time the drive will also use the SLC blocks whenever possible to move data through faster through an ‘aggressive evacuation’ policy.īasically, the WD Black NVMe SSD is designed to use its fastest flash memory at all times and reduce latency with plenty of other ‘house cleaning’ and ‘garbage collection’ background processes. Any spillover would move over to the slower, read focused TLC NAND. storing data), but WD has implemented tiered caching to speed up the overall system.įor example, if you were to move a mass of photos, the drive would first attempt to move as much data using its dedicated SLC blocks because they’re designed for burst workloads such as this. A larger portion of the drive relies on Triple Level Cell (TLC) 3D NAND that’s more suited read uses (i.e. diagnostics, update the firmware, and control the SN850s modest RGB lighting display. The Dashboard lets you check the drive status (space allocated, volumes, and temperature), run S.M.A.R.T. Western Digital’s new SSD is significantly faster than the previous Black PCIe SSD, which only topped out at 2,050 MB/s and 800 MB/s sequential read and write speeds, respectively.Įach Black NVMe SSD drive also incorporates a sliver of SLC (Single Level Cell) 3D NAND, which is famed for being the fastest form of flash memory even though it can only really move a small amount of bits. For software, the company provides the WD Black Dashboard, which weve seen in other products in the lineup such as the WD Black D50 Game Dock NVMe SSD. ![]()
