4TBPCIe Gen4 x4 NVMeUp to 7,300MB/sHeatsink ·PS5 Ready

The WD_BLACK SN850X 4TB with heatsink, part number WDS400T2XHE-00BCA0, is a high-end PCIe Gen4 internal M.2 2280 NVMe SSD engineered for serious gamers and creators. Its integrated low-profile heatsink keeps performance consistent under heavy load and is sized to fit the PlayStation 5, making it one of the best large-capacity drives for both PC gaming rigs and console storage expansion.

With sequential reads up to 7,300MB/s, writes up to 6,600MB/s and random performance up to 1,200K IOPS, the SN850X delivers near the top of Gen4 speed. Carrying EAN 0718037901480 and MPN WDS400T2XHE-00BCA0, this 4TB model uses WD 3D TLC NAND, features Game Mode 2.0 and nCache 4.0, is rated for 2400TBW and is backed by a 5-year limited warranty.

Compatibility note
This drive uses the M.2 2280 PCIe Gen4 x4 NVMe interface and includes an integrated heatsink. The low-profile heatsink is designed to fit the PlayStation 5’s storage expansion slot as well as desktop motherboards — check clearance on compact laptops, as the heatsink adds height. It is backward compatible with PCIe Gen3 at reduced speed, and will not work in SATA-only M.2 slots.

Frequently Asked Questions

Does this work in the PlayStation 5?
Yes. The SN850X is a PCIe Gen4 M.2 2280 drive that meets thePS5’s speed requirement, and this version’s low-profile heatsink is designed to fit thePS5 storage expansion slot, giving you a huge 4TB of extra game storage.
Why choose the heatsink version?
The integrated heatsink keeps the drive cooler under sustained heavy load, helping maintain peak performance and preventing thermal throttling. It is essential for thePS5 and useful in desktops without their own M.2 cooling.
Will it fit my laptop?
The heatsink adds height, so it may not fit thin laptops. For a laptop, check clearance or choose the non-heatsink SN850X. In a desktop with a standard M.2 slot, it fits comfortably.
Is 4TB worth it for gaming?
Modern games can exceed 100-200GB each, so 4TB lets you keep a large library installed without constantly deleting and re-downloading. Combined with Gen4 speeds and Game Mode 2.0, it delivers fast loads across your whole collection.
Singular Expert Insight
The WD_BLACK SN850X is one of the best gaming SSDs of its Generation, and the 4TB heatsink model is a standout for two audiences:PS5 owners who want maximum storage in the console’s expansion slot, and PC gamers building a high-end rig with a big, fast game library. The integrated heatsink and Game Mode 2.0 keep performance consistent under load. If you only need speed for everyday tasks a cheaper Gen4 drive will do, but for serious gaming at 4TB the SN850X is exactly the right tool. Browse the full range in our internal SSDs.

Buyer's Guide

Buy it if
You want a top-tier 4TB Gen4 gaming SSD for aPS5 (heatsink fits the expansion slot) or a high-end PC, with fast loads, Game Mode 2.0 and a 5-year warranty.
Skip it if
You need it for a thin laptop (the heatsink adds height — pick the non-heatsink model), you only do light everyday tasks, or you are on a tight budget.
Also consider
The SN850X without heatsink for laptops, smaller SN850X capacities (1TB/2TB) to save money, or the Crucial T710 if you have a PCIe Gen5 desktop.
