WD_BLACK SN850X 2TB M.2 2280 Solid State Drive
2TBPCIe Gen4 NVMeM.2 2280Up to 7300 MB/s1200 TBW
The WD_BLACK SN850X 2TB (part number WDS200T2X0E) is a M.2 2280 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.
Before you buy: this drive needs a free M.2 2280 slot that supports NVMe (M key, PCIe). This is the bare module with no heatsink. That keeps it thin enough for laptops and for slots under a graphics card, but a PlayStation 5 requires a heatsink, so choose the WDS200T2XHE version or fit an aftermarket one. 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.
✓ DirectStorage titles
Supports the Microsoft DirectStorage path that streams assets straight from the SSD to the graphics card.
✓ 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.
Onboard DRAM cache
Unlike the DRAM-less SN770M and SN7100, the SN850X carries its own DRAM cache, which helps sustained performance.

Frequently Asked Questions
Does the WDS200T2X0E fit my laptop or motherboard?
It needs an M.2 2280 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 WDS200T2X0E work in a PlayStation 5?
Sony requires an M.2 NVMe drive with a heatsink. This part number is the bare version without one, so you would need a compatible aftermarket heatsink, or choose the WDS200T2XHE version which ships with one fitted.
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 WDS200T2X0E?
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. This bare version is the right one for a laptop or a slot under a graphics card; budget for a heatsink if it is going into a console. Browse our internal SSDs or, for bulk capacity at a lower cost per terabyte, our NAS hard drives.
Buyer's Guide
Buy this if
You want a fast Gen4 NVMe drive with onboard DRAM for a gaming PC, workstation or laptop.
Skip if
You are building a NAS cache or a 24x7 server. WD Red SN700 has far higher endurance for that duty.
Also consider
The heatsink version WDS200T2XHE for a console, WD_BLACK SN7100 for a cooler low-power drive, or WD Red SN700 for NAS use.
