Actual performance depends on system hardware, firmware, workload, temperature, and operating conditions.

1TB Storage Capacity

The 1TB capacity provides substantial high-speed storage for games, applications, and other files.

It can be used for:

• PS5 games
• PS4 games
• PC games
• Windows
• Applications
• DLC
• Game updates
• Photos & videos
• Creative projects
• Frequently accessed files

Actual usable formatted capacity is lower than the advertised 1TB.

PlayStation 5 Compatibility

The SN850X with heatsink is suitable for installation in the PS5 M.2 expansion slot when used according to Sony's M.2 SSD requirements.

PS5 Usage

• Store PS5 Games: Yes
• Install PS5 Games: Yes
• Play PS5 Games Directly: Yes
• Store PS4 Games: Yes
• Play Compatible PS4 Games: Yes

Unlike a USB external HDD, PS5 games do not need to be transferred back to the console's internal SSD before playing.

Integrated Heatsink

The WDS100T2XHE comes with a factory-installed heatsink.

The heatsink helps:

• Dissipate heat
• Manage SSD temperatures
• Maintain sustained performance
• Reduce thermal throttling
• Support demanding gaming workloads

Heatsink Included: Yes

This is the major physical difference from the WDS100T2X0E, which is the SN850X 1TB version without an integrated heatsink.

PCIe Gen4 x4 NVMe

The SN850X uses a PCIe 4.0 x4 interface for high-speed storage communication.

• PCIe Generation: Gen4
• PCIe Lanes: x4
• Storage Protocol: NVMe
• Form Factor: M.2 2280

A compatible PCIe Gen4 system is required to achieve maximum rated performance.

M.2 2280 Form Factor

The SN850X uses the standard M.2 2280 form factor.

• Width: 22mm
• Length: 80mm SSD PCB class
• Form Factor: M.2 2280
• Installation: Internal

The integrated heatsink adds to the drive's overall physical dimensions compared with the bare M.2 version.

Actual benefits depend on the game and system configuration.
