Western Digital Black SN850X SSD disk 1TB

The Western Digital Black SN850X 1TB with heatsink is a high-performance internal SSD designed for gaming PCs, workstations, and performance-oriented systems. Built on the PCIe 4.0 x4 NVMe interface, it provides blazing fast sequential read speeds up to about 7,300 MB/s and sequential write speeds up to about 6,300 MB/s, ensuring rapid boot times, quick game loads, and responsive workflows. The compact M.2 2280 form factor includes an integrated heatsink, helping manage temperatures during sustained heavy usage and making it compatible with systems (including PlayStation 5) that require a heatsink for expansion storage. High random IOPS performance — up to ~800,000 read and ~1,100,000 write — along with a 600 TBW endurance rating and 5-year limited warranty make it a reliable choice for demanding applications and everyday computing. RGB lighting can be programmed via the WD_BLACK Dashboard on Windows for personalized aesthetics.
