4TB WD_Black SN850X NVMe SSD

The WD_Black SN850X NVMe SSD with Heatsink is a top-tier PCIe Gen4 gaming drive built for blazing-fast loads and sustained performance. It delivers up to 7,300 MB/s read and 6,600 MB/s write speeds (1TB–4TB models), massive random IOPS (up to 1.2M), and capacities from 1TB to 8TB—perfect for huge game libraries, 4K editing, or heavy multitasking. The included heatsink keeps thermals in check during intense sessions (ideal for PS5 expansion or PC rigs with glass panels; some versions add RGB lighting customizable via WD_BLACK Dashboard). Game Mode 2.0 optimizes predictive loading and thermal management.
