Western Digital WD_BLACK SN850 1TB PCIe 4.0 x4 NVMe M.2 2280

The WD_BLACK SN850 is the officially licensed PS5 storage upgrade that just works. It hits 7000 MB/s reads, installs in minutes thanks to the pre-attached heatsink, and carries a 4.8-star rating from over 3,300 owners. At $260 for 1TB, it's not the cheapest Gen4 drive, but the convenience and guaranteed compatibility justify the premium for most console owners. If you want a no-drama PS5 expansion, this is the one to get.

The headline numbers are 7000 MB/s sequential read and 5300 MB/s sequential write. For a PS5, that's more than enough. Sony's own internal drive hits around 5500 MB/s, so this WD_BLACK actually outpaces the stock storage. In practice, that means game loads, fast travel, and texture streaming all feel snappy. You won't notice a difference between this and the internal drive in most games, which is exactly what you want from an expansion drive.

Our database puts this drive's speed in the 79th percentile overall, which is solid but not the absolute fastest Gen4 drive on the market. Drives like the Samsung 9100 PRO and Crucial T500 push higher in some benchmarks. But here's the thing: the PS5's I/O pipeline caps real-world gains beyond a certain point. The SN850's random performance sits at the 62nd percentile, which is about average for this class. For console use, that's fine. You're not running a database server, you're loading Spider-Man. The endurance rating is the weak spot at the 15th percentile, but for a console drive that mostly reads data, that's not a practical concern for most people.

The Samsung 9100 PRO is the performance king in this space, with faster sequential and random numbers across the board. But it's also more expensive and arguably overkill for a PS5. The Crucial T500 is probably the closest direct competitor, offering similar Gen4 speeds at a lower price, though you may need to add your own heatsink depending on the variant you buy. The Kingston Fury Renegade is another strong option, often priced aggressively and with excellent write endurance.

The SanDisk WD_BLACK WDS400T2XHE is essentially this drive's sibling, since SanDisk and WD are the same company now. It offers 4TB of capacity, which is a huge advantage if you want to never think about storage again. The Lexar NM1090 PRO is a newer entrant with strong specs, but it doesn't have the same track record or user review volume as the WD_BLACK. For PS5 owners specifically, the SN850's official licensing and pre-installed heatsink give it an edge in peace of mind that none of these competitors quite match.

Pricing is where this gets tricky. The US listing shows $260 for the 1TB model, and the Canadian listing is CAD 495. That's not cheap for a terabyte of Gen4 storage. In fact, our database puts its affordability at the 30th percentile, meaning most competing drives cost less per gigabyte. You're paying a premium for the official PS5 branding and the convenience of a pre-installed heatsink.

Is that premium worth it? If you want zero hassle and guaranteed compatibility, yes. The heatsink alone saves you from buying a third-party one and hoping it fits under the PS5's expansion bay cover. But if you're comfortable installing your own heatsink, you can often find comparable Gen4 drives for less. The Crucial T500 and Kingston Fury Renegade both offer similar or better performance at more aggressive price points. The value here is in the convenience, not the raw specs.

The WD_BLACK SN850 with heatsink is Western Digital's officially licensed storage expansion for the PlayStation 5. It's a 1TB M.2 2280 PCIe 4.0 NVMe drive that slots right into the PS5's expansion bay, and WD made sure the heatsink is pre-attached so you don't have to mess with thermal pads or third-party cooling. That's a bigger deal than it sounds, because Sony's spec requirements for PS5 drives are picky, and this one is built to meet them out of the box.

Who's this for? PS5 owners who are tired of juggling game installs. The console's built-in 825GB fills up fast when big titles routinely eat 80 to 100GB. This drive adds a full terabyte of space, which WD says translates to roughly 50 games based on a 36GB average. Realistically, with modern AAA games, you're looking at more like 10 to 15 big titles, but that's still a massive quality-of-life upgrade.

What makes it interesting is the combination of official licensing and raw speed. The drive is rated for 7000 MB/s reads and 5300 MB/s writes, which puts it comfortably above Sony's minimum 5500 MB/s recommendation. In our database, its speed lands in the 79th percentile, which is strong but not chart-topping. The real story here is that it's a no-drama install with performance that keeps up with everything the PS5 can throw at it.

PC builders looking for a high-end NVMe drive should look elsewhere. The SN850's endurance rating is in the 15th percentile, which is a real concern for write-heavy workloads like video editing or database use. Its random performance is also just average, so you're not getting workstation-class responsiveness. For PC use, the Crucial T500 or Samsung 9100 PRO are better choices with stronger endurance and faster random I/O.

If you're on a tight budget, this drive's affordability ranking in the 30th percentile means you're paying a premium for the official PS5 branding and pre-installed heatsink. You can often find comparable Gen4 drives for $30 to $50 less if you're willing to install your own heatsink. The Kingston Fury Renegade is a good budget alternative that still delivers strong performance. But if you want the easiest possible PS5 upgrade and don't mind paying for convenience, this drive is hard to beat.

If you own a PS5 and want the easiest possible storage upgrade, buy this drive. The installation is genuinely simple, the performance is more than adequate, and the user reviews back it up. With a 4.8-star average across over 3,300 ratings and user sentiment in the 95th percentile, this is one of the most consistently well-reviewed PS5 accessories we've seen. The price stings a bit, but you're paying for certainty.

If you're building a PC or want maximum performance per dollar, look elsewhere. The SN850's endurance rating is weak for a workstation drive, and its random performance is nothing special. For PC users, the Crucial T500 or Kingston Fury Renegade offer better value. But for the specific job of expanding a PS5, this drive nails it. It's the boring, reliable choice, and sometimes that's exactly what you want.
