The WD_BLACK 4TB SN850X NVMe SSD with Heatsink (Retail SKU: WDBB9H0040BNC) is the definitive storage upgrade for hardcore gamers, content creators, and PS5 enthusiasts. Moving massive assets, rendering 8K video, and loading expansive open-world games requires immense bandwidth. By maxing out the PCIe Gen4 interface, the SN850X drastically cuts down loading screens, allowing you to spend more time playing and less time waiting.
Expanded Key Features
Near-Max PCIe Gen4 Speeds: Reach the pinnacle of the PCIe Gen4 x4 interface with staggering sequential read speeds up to 7,300 MB/s and write speeds up to 6,600 MB/s, delivering insanely fast responsiveness for heavy computing.
Integrated Thermal Heatsink: The factory-installed, low-profile aluminum heatsink dissipates heat rapidly to prevent thermal throttling, ensuring you maintain peak frame rates and performance during sustained, heavy workloads.
Perfect for PlayStation 5: The built-in heatsink model is officially tested and verified to fit perfectly inside the PS5's M.2 expansion slot, easily expanding your console storage by a massive 4TB.
Colossal 4TB Storage Capacity: Stop deleting your favorite titles to make room for new updates. With 4 Terabytes of 3D TLC NAND storage, you can keep dozens of massive AAA games ready to play at a moment's notice.
Game Mode 2.0 & DirectStorage: Utilizing the downloadable WD_BLACK Dashboard (Windows only), Game Mode 2.0 automatically optimizes background processes and introduces load prediction and overhead balancing. Combined with Microsoft DirectStorage support, game assets bypass the CPU for near-instant rendering.
Built to Last: Engineered for reliability, the 4TB SN850X boasts an impressive endurance rating of 2400 TBW (Terabytes Written) and a 1.75 million-hour MTTF (Mean Time To Failure).
Why This Product Stands Out
The WD_BLACK SN850X stands out by offering a flawless mix of raw speed, massive 4TB density, and thermal reliability. Unlike bare drives that can overheat under sustained load, the included heatsink makes it a true plug-and-play solution that brings desktop-grade PC speeds seamlessly into the PlayStation 5 ecosystem.
