Western Digital (WD) Black SN850X
is a high-performance PCIe Gen4 x4 NVMe solid-state drive (SSD) designed for gaming and intensive use. The model without a heatsink is suitable for desktop PCs with motherboard-integrated heatsinks or laptops with adequate cooling. An 8TB capacity model was released, but it was generally noted as a high-capacity niche option.

Product specifications
Specifications vary slightly between the 1TB and higher capacity models. The 8TB model uses different flash memory and has slightly lower sequential performance ratings than the 2TB and 4TB variants.
