4TB SSD PCIe 4.0 NVMe M.2 2280

The WD_BLACK SN850P 4TB is a top-tier Gen4 SSD that's officially licensed for PS5, with 7300 MB/s reads, a beefy 2400 TBW endurance rating, and an included heatsink. It's expensive, sitting in the bottom 10% for affordability, and prices swing wildly between retailers, from €812 to €1,470 in Europe. If you want the safest, easiest PS5 storage upgrade and can stomach the premium, this is the drive to buy. PC users and value hunters should look at the Samsung 9100 PRO or Kingston FURY Renegade instead.

Let's talk about what those numbers actually mean. The 7300 MB/s read speed is effectively maxing out the PCIe 4.0 interface, and in our database that puts this drive in the top tier of Gen4 SSDs. For PS5 use, the console caps out around 6500-7000 MB/s in real-world transfers anyway, so you're not leaving performance on the table. Game load times will be indistinguishable from the internal drive, and in some cases you might even see a slight edge thanks to the DRAM cache handling asset streaming more smoothly.

The random performance is where this drive really flexes. 1200K random read IOPS is excellent for a consumer drive, and it translates to snappy texture streaming in open-world games and faster level loads in games that hammer the storage with lots of small file requests. The 2400 TBW endurance rating is also worth calling out. That's a lot of write headroom, roughly double what you'd get from many mid-range 4TB drives. For a game drive that mostly sees reads after the initial download, you'll likely never approach that limit, but it's reassuring if you also plan to use this in a PC for video editing or other write-heavy workloads.

The most direct competitor is the Samsung 9100 PRO, which is Samsung's flagship Gen4 drive. The 9100 PRO trades blows with the SN850P on sequential speeds and actually edges it out on some random workloads, but Samsung's 4TB model typically costs more and doesn't come with a PS5-specific heatsink. If you're building a high-end PC and want the absolute best Gen4 drive, the 9100 PRO is worth a look. For PS5 use, the SN850P's official license and simpler install make it the more practical choice.

On the value side, the Kingston FURY Renegade 4TB and Crucial T710 are both excellent Gen4 drives that undercut the SN850P on price. The FURY Renegade hits similar sequential speeds and has a solid reputation for reliability, while the T710 is a newer drive with strong endurance numbers. The trade-off is that neither is officially licensed for PS5, so you'll need to verify heatsink clearance and may not get the same plug-and-play experience. The Lexar NM1090 PRO is another budget-friendly option, though its endurance rating trails the SN850P. If you're comfortable doing a little research, you can save real money. If you want the safe bet, this WD_BLACK is it.

Here's where things get tricky. This drive is not cheap, and our database puts it in the bottom 10% for affordability among comparable SSDs. The US listing sits at $865, while UK buyers can grab it for £699. But the real story is the price spread in Europe and Canada. In EUR, prices range from €812 to €1,470 across four listings. That's a €658 gap for the exact same drive. In CAD, you're looking at $1,585 to $2,027, a $442 spread. If you're shopping in those regions, the cheapest listing is the only sensible option, and even then you're paying a premium over non-licensed alternatives.

The value proposition really depends on how much you value peace of mind. A drive like the Kingston FURY Renegade 4TB or the Crucial T710 will deliver nearly identical real-world performance for less money, but you'll need to add your own heatsink and do a bit more homework on compatibility. For PS5 owners who just want to buy something, install it, and never think about it again, the SN850P's official license and included cooling justify some of the premium. Just don't expect the PlayStation logo to make your games load any faster.

The WD_BLACK SN850P is Western Digital's officially licensed PlayStation 5 SSD, and it's basically the storage equivalent of buying the first-party controller instead of a third-party knockoff. You pay a premium for the logo, but you also get a drive that's guaranteed to slot into your PS5 without any drama. This 4TB model is the big boy of the lineup, promising room for roughly two dozen games, which matters when modern titles are routinely pushing 100GB or more.

Under the hood it's a proper PCIe 4.0 NVMe drive with a DRAM cache and Western Digital's own controller. The headline numbers are 7300 MB/s sequential reads and 6600 MB/s writes, which puts it right at the ceiling of what the PS5's M.2 slot can actually use. Random performance is no slouch either, at 1200K read IOPS and 1100K write IOPS. This isn't a budget drive with a fancy sticker, it's a genuinely fast piece of silicon.

Who's this for? PS5 owners who are tired of deleting games to make room for new ones, and who don't want to spend an afternoon researching whether some cheaper drive will cause stuttering or overheating issues. It's also a solid pick for PC builders who want a high-endurance Gen4 drive and don't mind paying for the PlayStation branding. The included heatsink means you won't need to buy a separate cooling solution, which is one less thing to worry about.

If you're building a PC and don't own a PS5, skip this drive. The PlayStation license adds cost without adding performance, and you can get equivalent or better Gen4 speeds from the Samsung 9100 PRO or Kingston FURY Renegade for less money. The included heatsink is nice, but most modern motherboards already have M.2 cooling built in, so it's not a meaningful advantage.

Value-conscious PS5 owners should also think twice. The SN850P is a safe choice, but it's not the only safe choice. Drives like the Crucial T710 or Lexar NM1090 PRO will handle PS5 game storage just fine with a compatible heatsink, and you'll save a meaningful chunk of change. If you're willing to spend 20 minutes researching compatibility and installing a heatsink, the savings are real. This drive is for people who want the easiest possible path, not the cheapest one.

For PS5 owners who are out of storage and want the simplest possible upgrade, the SN850P 4TB is an easy recommendation. It's fast enough to max out the console, the heatsink fits perfectly, and the official license means Sony has blessed this specific drive for use in their hardware. You'll pay more than you would for a DIY solution, but you're buying convenience and certainty. The 4.9-star average across 710 reviews suggests most buyers feel the same way.

For PC users, the calculus shifts. The SN850P is still a great drive, but the PlayStation branding adds cost without adding performance. Unless you specifically want the included heatsink or find it on sale at the low end of that price range, you're better off with a Samsung 9100 PRO or Kingston FURY Renegade. And if you're value-conscious in general, the price spread between retailers means you should absolutely shop around. Paying €1,470 when another store has it for €812 is just throwing money away.
