WD_BLACK SN850X 2TB M.2 2280 with heatsink Solid State Drive
2TBPCIe Gen4 NVMeM.2 2280 with heatsinkUp to 7300 MB/sRGB heatsink
The WD_BLACK SN850X 2TB (part number WDS200T2XHE) is a M.2 2280 with heatsink internal solid state drive on PCIe Gen4 x4 NVMe, reaching up to 7300 MB/s sequential read and 6600 MB/s sequential write. It sits at the top of the Western Digital consumer NVMe range, aimed at gaming PCs and creative workstations, with Game Mode 2.0 firmware that reduces loading overhead and adaptive thermal management to hold speed under sustained load. This part number ships with an integrated heatsink carrying customisable RGB lighting, and is the version suited to a PlayStation 5.
Before you buy: this drive needs a free M.2 2280 with heatsink slot that supports NVMe (M key, PCIe). The heatsink adds height: the module is 8.90 mm thick against 2.38 mm for the bare version. That clears a PlayStation 5 expansion bay and most desktop motherboards, but it will not fit under a graphics card sitting directly over the M.2 slot, and it will not fit a laptop. It is supplied bare, without a mounting screw or cloning software licence, so check clearance under a laptop cover or a graphics card before ordering.
Best For
✓ Gaming PCs
Up to 7300 MB/s sequential read with Game Mode 2.0 firmware, which predicts and pre-loads game data to cut level load times.
✓ Creative workstations
Gen4 flash handles 4K and 8K video timelines and large RAW photo libraries without an external scratch disk.
✓ PlayStation 5 expansion
The integrated heatsink meets the Sony requirement for an M.2 drive in the PS5 expansion bay, and the 8.90 mm height clears the cover.
✓ Large game libraries
At 2TB you can keep dozens of modern titles installed instead of constantly uninstalling to make room.
Key Features
Up to 7300 MB/s read
Near the practical ceiling of PCIe Gen4 x4, roughly twice what a Gen3 drive can deliver.
Up to 1,200,000 random read IOPS
Random performance determines how quickly a game or project actually loads, more so than sequential speed.
Game Mode 2.0
Predictive loading and overhead balancing firmware that Western Digital tunes specifically for game workloads.
Adaptive thermal management
The controller manages its own temperature to sustain high speeds for longer before throttling.
1200 TBW endurance
Rated for 1200 terabytes written, comfortably beyond what a desktop or gaming workload will reach in normal use.
Integrated RGB heatsink
A fitted heatsink with customisable lighting, so no separate cooler is needed and PlayStation 5 requirements are met out of the box.

Frequently Asked Questions
Does the WDS200T2XHE fit my laptop or motherboard?
It needs an M.2 2280 with heatsink slot wired for NVMe (M key, PCIe). A slot keyed only for SATA only will not work with this drive even though it may physically fit. Check your manual for the slot type and length before ordering.
Does the WDS200T2XHE work in a PlayStation 5?
It is the heatsink version, which is what Sony requires for a drive in the PS5 expansion bay, and at 8.90 mm it fits under the cover. Check the current Sony requirements for your console revision before ordering, since firmware and specifications change.
Do I need a PCIe Gen4 motherboard?
No. The drive is backward compatible and will run in a Gen3 slot, but it will be limited to roughly Gen3 speeds. To see the full 7300 MB/s you need a Gen4 M.2 slot wired directly to the CPU.
What do I need to know before buying the WDS200T2XHE?
It ships as a bare module with no mounting screw or cloning software. Fitting it usually means removing a small screw on the motherboard or laptop, and you should back up your data before migrating an operating system to a new drive.
Singular Expert Insight
The SN850X remains the sensible choice when you want a Gen4 drive with onboard DRAM rather than a cheaper DRAM-less design, and the 1200 TBW rating is far beyond what desktop use will consume. Be realistic about the speed though: outside DirectStorage titles and large file copies, the gap between a good Gen3 and a good Gen4 drive is small in day to day use. The fitted heatsink makes the buying decision simple for a PS5 or a hot motherboard slot, but check clearance if a graphics card sits over the M.2 slot. Browse our

Buyer's Guide
Buy this if
You want a Gen4 drive that drops into a PlayStation 5 or a desktop with no separate cooler to buy or fit.
Skip if
The drive is going into a laptop or a slot under a graphics card. The 8.90 mm heatsink will not clear; buy the bare WDS200T2X0E instead.
Also consider
The bare WDS200T2X0E if you have your own cooling, or WD Red SN700 for NAS duty.
