The WD_BLACK SN850X is an 8TB PCIe 4.0 NVMe M.2 SSD with a heatsink, suited to PC gamers who want substantial game storage and fast loading, with sequential reads up to 7,200 MB/s and writes up to 6,600 MB/s.
Recommended For
- PC gamers with large libraries who want to keep many games installed on one drive and avoid regularly moving or deleting titles. The 8TB capacity is the main fit; the PCIe 4.0 performance also suits a modern gaming PC.
- PS5 owners who want a very large internal game library on an M.2 drive. Sony supports compatible M.2 SSDs up to 8TB and requires a heat-dissipation solution; check the console’s fit requirements before installation.
- PC users who regularly work with large files—such as media libraries or sizable project data—and want high-capacity NVMe storage for frequent reads and writes.
- Builders with a compatible M.2 2280 PCIe 4.0 slot who want a pre-installed heatsink rather than choosing and fitting a separate M.2 cooling solution.
Real-World Use Scenarios
- A PC gamer with a large library can keep more games installed on one drive, reducing the need to uninstall titles to make room. Review testing found the 8TB model handled large file transfers quickly; game load times still depend on the game and the rest of the PC.
- A PS5 owner who wants more internal game storage can use a compatible M.2 expansion drive to store and play PS5 and PS4 games directly, with less frequent shuffling between storage devices. Check the console’s M.2 and heatsink size requirements before installing.
- A PC gamer who regularly installs or updates large games can use the SN850X as a fast game-library drive, helping reduce storage-related waits during installs, transfers, and loading. The benefit varies by game and system; an SSD upgrade does not guarantee a noticeable change in every title.
- A creator or workstation user moving large project folders can use the drive for active files and frequent transfers, with review benchmarks showing strong performance on large-file workloads. It is fast local storage, not a substitute for a separate backup.

Reference Q&A
Q: WD_BLACK SN850X 8TB or Samsung 990 PRO—what should I choose?
A: Choose the SN850X if you want an 8TB drive in one M.2 slot; Samsung lists the 990 PRO in capacities up to 4TB. The 990 PRO has higher advertised sequential speeds at its top capacity, while independent tests show that gaming results can vary by benchmark. For a gaming PC or PS5 expansion where capacity is the priority, the SN850X 8TB is the more direct fit.
Q: Is the SN850X 8TB worth choosing over the 4TB version?
A: Choose the 8TB version if you want more game and file storage in a single M.2 drive. Choose 4TB if that capacity is enough or you prefer splitting storage across drives; independent reviews found that the 8TB model can be slightly slower than smaller SN850X capacities in some tests. The 8TB model is rated for up to 7,200 MB/s read and 6,600 MB/s write, while WD advertises up to 7,300 MB/s read for 1TB–4TB models.
Q: Should I upgrade from the WD_BLACK SN850 to the SN850X?
A: Choose the SN850X for a new build or when you want the higher rated sequential speeds, updated gaming features, and capacity options up to 8TB. If your SN850 already has enough space and meets your needs, reviews describe the SN850X as an incremental revision rather than a major change in everyday gaming load times.
Q: Can I use the SN850X 8TB with heatsink in a PS5, or should I choose a PC drive?
A: The SN850X with heatsink is a candidate for PS5 storage expansion when its dimensions fit the console’s M.2 bay; Sony specifies PCIe Gen4 x4 NVMe drives from 250GB to 8TB and requires effective heat dissipation. For a PC, choose the heatsink version if you need its cooling included; otherwise, a motherboard heatsink may be suitable if it fits the drive and provides adequate cooling.
Q: Is this 8TB SSD compatible with a PS5?
A: Yes. This is the heatsink-equipped M.2 2280 PCIe Gen4 x4 version, and the comparable 8TB SN850X listing on Best Buy identifies it as PS5-compatible. Check that your console’s expansion bay can accommodate the drive and follow the console’s installation requirements.
Q: Will this SSD work in a desktop PC?
A: It can work in a desktop with an available M.2 2280 slot that supports PCIe Gen4 x4 NVMe drives. Confirm motherboard compatibility and heatsink clearance before installation.
Q: Can I install this SSD in a laptop?
A: Only if the laptop supports an M.2 2280 NVMe PCIe drive and has enough physical clearance for this model’s built-in heatsink. Check the laptop’s specifications before buying; an M.2 slot alone does not guarantee fit.
Q: What read and write speeds does the 8TB model offer?
A: The supplied specifications list sequential read speeds up to 7,200 MB/s and write speeds up to 6,600 MB/s for this 8TB model. Actual speeds depend on the system and workload.
Q: Does the 8TB SN850X with heatsink fit and work in a PS5 Pro?
A: The product is specified for PS5 use, and Reddit users report installing the 8TB heatsink model in both a PS5 and PS5 Pro. One user said it fit and worked in both consoles. Because that is user-reported experience, check clearance for your console model before buying.
Q: Is the 8TB SN850X worth buying for a NAS?
A: It can suit a compact NAS when you need high-capacity NVMe storage for uses such as containers or caching. For mostly storing and streaming media, Reddit users note that NVMe speed may go unused, so the price premium may not be worthwhile. The drive is rated for 4,800 TBW, but that specification alone does not guarantee lifespan in a particular workload.
Q: Is the 8TB capacity worth the extra cost?
A: It is most relevant if you need to keep a large game library or other files on one fast drive. Reddit users discuss the 8TB model as costly, so if you do not expect to use that much space, a lower-capacity drive may be a more practical choice.
