The WD_BLACK SN850X powers your gaming PC : NVMe PCIe 4.0 in M.2 2280 format, up to 7300 MB/s read and 6300 MB/s write speeds. Optional heatsink to maintain performance, Game Mode 2.0 via WD_BLACK Dashboard , DirectStorage support, and a 5-year warranty .
Strengths
- Up to 7300 MB/s read speed ( PCIe 4.0 ) for lightning-fast loading
- 3D TLC NAND and capacities up to 8TB for more games
- Optional heatsink , Game Mode 2.0 , DirectStorage for stable performance
Professional speed, immediate responsiveness
With read speeds of up to 7300 MB/s and write speeds of up to 6300 MB/s , the SN850X reduces lag and texture pop-in. High IOPS ( 800K read / 1100K write) ensure exceptional responsiveness on NVMe PCIe 4.0 .
Controlled thermals, lasting performance
The model with a heatsink limits thermal throttling during long sessions and maintains high throughput. Ideal for compact cases and sustained workloads.
Software & the future of gaming
Activate Game Mode 2.0 in WD_BLACK Dashboard (Windows) and take advantage of DirectStorage for accelerated loading, plus a set of modern features (predictive loading, balancing, thermal management).
With or without a heat sink?
The SN850X is available with and without a heatsink. The version with a heatsink is suitable for motherboards without an M.2 heatsink, compact cases, sustained workloads, and the PS5 (the only compatible version). It reduces thermal throttling to maintain speed. The version without a heatsink is ideal if your motherboard already has an efficient M.2 heatsink or if you're on a budget. Check the maximum thickness and, if necessary, update your BIOS .
Why should I buy the WD_BLACK SN850X NVMe SSD – 1TB?
Because it combines extreme speed ( 7300 MB/s ), stability ( heatsink option), gaming software ( Game Mode 2.0 ) and DirectStorage compatibility, with a 5-year warranty . You launch faster, you play harder.
