WD Black SN850X 4TB M.2 PCIe 4.0 NVMe SSD

The SanDisk WD_BLACK SN850X is a high-capacity internal solid-state drive designed for demanding computing environments such as professional workstations and high-end gaming setups. This M.2 2280 unit utilizes the PCIe 4.0 interface, leveraging x4 lanes for high bandwidth data transfer rates. Sequential read performance reaches up to 7300 MB/s, complemented by sequential write speeds up to 6600 MB/s. This performance profile facilitates rapid loading of large files and minimizes system latency during intensive multitasking operations.

The drive incorporates 3D TLC NAND flash technology managed by the dedicated WD 20-82-20035-B1 controller. This configuration ensures sustained performance stability, essential for continuous read/write cycles typical of power users. With an endurance rating of 2400 TBW (Terabytes Written), the 4 TB model is built for longevity under heavy usage scenarios. The drive supports the NVMe 1.4 protocol, optimizing communication efficiency between the storage and the host system.

Measuring 80 mm in length and 22 mm in width, the compact M.2 form factor allows for integration into slim laptops and modern desktop motherboards. Temperature monitoring is integrated to manage thermal performance during sustained high-load operations. For data security requirements, the drive includes support for TCG Opal 2.01 algorithms.
