WD Black SN850X: High-performance NVMe SSD with 4 terabytes of storage space
The Western Digital Black SN850X NVMe SSD is a particularly small M.2 SSD. It is installed in the M.2 slot of the same name and addressed via the NVMe interface and connected via four PCI Express 4.0 lanes. The 4 TB Western Digital Black SN850X NVMe SSD achieves extremely high read and write rates of 7,300 and 6,600 MB/s respectively.

This is also thanks to the 3D NAND TLC flash with 112 layers and the in-house controller from Western Digital, including a 2 GB DDR4 cache. The excellent performance is all the more impressive in view of the small ultrabook or tablet-compatible size of the drive, after all, the Western Digital Black SN850X NVMe SSD is just under 8 cm long and 2.34 cm wide. However, a free M.2 NVMe connection must be available on the device for use. You should ask the manufacturer about compatibility before purchasing.

The user can activate the gaming mode via the software interface WD SSD Dashboard. Then the performance is optimized by completely disabling the power saving feature of the SSD. The software can be obtained free of charge from the manufacturers website.
