The WD_BLACK SN850X is a 1TB PCIe 4.0 NVMe M.2 2280 SSD with a built-in heatsink and read speeds up to 7,300 MB/s, suited to gamers seeking fast load times in a compatible gaming PC or PlayStation 5.
Recommended For
- PS5 owners who want to add internal M.2 storage for games they can play directly from the expansion drive, and prefer a model with its heatsink already installed.
- Gaming-PC builders with a compatible PCIe 4.0 M.2 slot who want a fast drive for game installs, loads, and file transfers; professional testing found strong real-world transfer and random-operation performance.
- PC users who move large files or run storage-heavy tasks and want a high-end Gen4 drive with a built-in heatsink for sustained use.
Real-World Use Scenarios
- A PS5 owner running short on space can install the SN850X in the console’s M.2 slot, then store and launch PS5 and PS4 games from it. The added space can reduce the need to remove games, while load times may be similar to the console’s internal SSD rather than dramatically faster.
- A PC gamer can use the SN850X as a dedicated game-library drive for installed titles and frequent play. Reviews found strong game-loading benchmark results, but an SSD upgrade should not be expected to increase in-game frame rates by itself.
- A gamer with a crowded system drive can move some large game installs to the SN850X and keep them available without reinstalling them each time storage gets tight. The 1TB model adds room, though how many games fit depends on their individual sizes.
- During long gaming sessions, a PC builder or PS5 owner can use this heatsink-equipped version without needing to add a separate SSD heatsink. The heatsink supports cooling, but it does not guarantee a visible performance difference in every system or workload.
- A Windows gamer can try Game Mode 2.0 through WD_BLACK Dashboard to prioritize game-related loading behavior. Reviews found that the feature’s real-world impact can be small, so it is best treated as an optional setting rather than a guaranteed shortcut.

Reference Q&A
Q: Is the WD_BLACK SN850X 1TB with heatsink a good fit for PS5, or should I choose another Gen4 SSD?
A: Choose this SN850X if you want a PCIe 4.0 M.2 drive with a heatsink already installed. Its listed sequential read speed of up to 7,300 MB/s exceeds Sony’s recommended 5,500 MB/s, and Sony requires effective heat dissipation for an M.2 expansion drive. Check that the heatsink’s full dimensions fit your console; Sony also notes that exceeding its recommended read speed does not guarantee identical performance in every game.
Q: WD_BLACK SN850X or Samsung 990 PRO for gaming—which should I buy?
A: Both are high-performance PCIe 4.0 SSDs, and reviews show that their relative results can vary by benchmark and game. The SN850X is a practical choice when its price is lower or you want this version’s built-in heatsink; consider the 990 PRO if it better suits your price, capacity, or setup. For gaming alone, the available testing does not establish a consistent real-world winner.
Q: Should I pay more for the SN850X instead of the WD_BLACK SN770?
A: Choose the SN850X when you want a higher-performance drive for a primary gaming or workstation build, or expect demanding storage workloads. The SN770 is a lower-cost PCIe 4.0 option that reviewers found capable in everyday use and shorter transfers. Compare current prices: the SN850X’s higher performance ceiling may not matter as much for a game library or routine PC use.
Q: Is the SN850X worth choosing over the older WD_BLACK SN850?
A: Choose the SN850X when prices are close and you want the newer model’s performance refinements. If the SN850 costs substantially less, it remains a PCIe 4.0 gaming SSD and may be the better value for ordinary gaming and PC use. Independent testing reports improvements with the SN850X, but the size of the difference depends on the workload.
Q: Will this SSD work in a PlayStation 5?
A: Yes. This 1TB model is listed as PS5-compatible and includes a heatsink. Confirm your console’s installation requirements before fitting it.
Q: Does this SSD come with a heatsink?
A: Yes. This is the heatsink-equipped version, which can help manage drive temperatures during use. Make sure the heatsink fits the device’s available M.2 space.
Q: Will it work in a laptop?
A: It can work in a laptop that supports an M.2 2280 NVMe PCIe drive, but check the laptop’s specifications and available clearance first. The included heatsink may not fit in every laptop.
Q: Can I use it in a PCIe Gen 3 M.2 slot?
A: It may work if the slot supports M.2 NVMe drives, but the drive will run at the slot’s Gen 3 limits rather than its advertised PCIe Gen 4 speeds. Check the device or motherboard specifications for NVMe support.
Q: Does the 1TB SN850X add storage to a PS5, or replace its internal SSD?
A: It installs in the PS5’s M.2 expansion slot and adds storage; it does not replace the console’s built-in SSD. The Reddit discussion describes choosing where to install games after adding the drive.
Q: Is the heatsink necessary for the SN850X in a PS5?
A: The listed WDS100T2XHE model includes a heatsink, so it does not require a separate one. In the Reddit discussion, users describe a heatsink as recommended for managing heat, though not mandatory.
Q: Is 1TB enough for a PS5 game library?
A: The drive adds 1TB of capacity, which may suit someone who manages their installed games. In the Reddit discussion, users differ: some consider 1TB sufficient, while others prefer 2TB for more room.
Q: Is the SN850X worth choosing over a cheaper compatible PS5 SSD?
A: The SN850X offers up to 7,300 MB/s sequential reads and includes a heatsink in this model. Reddit commenters report little practical difference between high-speed compatible drives for PS5 use, so compare price, capacity, and whether a heatsink is included.
