Western Digital 4TB SSD PCIe 4.0 NVMe

The WD_BLACK SN850P is the safest, easiest PS5 storage upgrade you can buy, with 4TB of space, 7,300 MB/s reads, and a heatsink that's guaranteed to fit. It's expensive, sitting near the bottom of the affordability rankings, but the 2,400 TBW endurance and 5-year warranty justify the premium for anyone who wants zero hassle. Shop around, because prices vary by hundreds of dollars between vendors. If you own a PS5 and want to stop deleting games, this is the one to get.

Let's talk numbers. The SN850P is rated for 7,300 MB/s sequential reads and 6,600 MB/s writes. That puts it in the top tier of Gen4 drives, and in practical terms it means load times on PS5 games are effectively indistinguishable from the console's internal storage. Sony's own spec requires at least 5,500 MB/s for expansion drives, so this clears that bar by a wide margin. You're not going to see stuttering or texture pop-in because the drive can't keep up.

Random performance is just as strong. 1,200K random read IOPS and 1,100K random write IOPS put this drive near the top of the charts for Gen4. For a console, that translates to snappy menu navigation and fast game switching. For a PC, it means the drive handles everything from booting Windows to scrubbing through 4K video without breaking a sweat. The DRAM cache helps keep those numbers consistent under sustained load, which is something cheaper DRAM-less drives can't always manage. The one thing to keep in mind: those peak numbers assume you're using the drive in a PCIe 4.0 slot. Drop it into a Gen3 system and you'll see roughly half the throughput, though it'll still feel fast.

The SN850P doesn't exist in a vacuum. The Samsung 9100 PRO is a Gen5 drive that's faster on paper, but it's also more expensive and overkill for a PS5, which can't even use Gen5 speeds. If you're building a high-end PC and want the absolute fastest storage, the Samsung is the better pick. But for PS5 owners, the SN850P's Gen4 speed is already more than the console can fully utilize, so the Samsung's extra headroom is wasted.

The Kingston FURY Renegade G5 and Crucial T710 are both strong Gen4 competitors that often come in cheaper than the SN850P. The Kingston is a favorite among PC builders who want top-tier performance without the console tax. The Crucial T710 is another solid option, though its availability can be spotty. The Seagate FireCuda 530R is probably the closest direct competitor, since it's also marketed toward PS5 users and comes with a heatsink. It's a good drive, but the SN850P's endurance rating and that official Sony license give Western Digital a slight edge for console buyers who want the safest possible choice. The SanDisk WD_BLACK WDS800T1X0M is essentially a sibling product, since SanDisk and Western Digital are the same company now, so expect similar performance with slightly different branding.

Here's where things get tricky. This drive is not cheap. In our database, it sits in the 9th percentile for affordability, which means it's one of the most expensive options in its class. The US listing is $865, and in Canada you're looking at anywhere from CAD 1,585 to CAD 2,027 depending on where you buy. That's a CAD 442 spread between the cheapest and most expensive Canadian listings, which is frankly ridiculous. If you're in Canada, do yourself a favor and find the CAD 1,585 listing before you even think about paying the higher price.

In Europe, the story is similar. EUR prices range from EUR 812 to EUR 1,100 across four listings in Germany, Spain, France, and Italy. That's a EUR 288 difference for the exact same drive. The cheapest EUR listing is the one to hunt for. The value proposition here is real, but only if you're paying the lower end of those ranges. At the high end, you're paying a premium for the PlayStation logo and the convenience of a pre-installed heatsink. Whether that's worth it depends on how much you value not having to think about compatibility.

The WD_BLACK SN850P is Western Digital's officially licensed PlayStation 5 SSD, and it's basically the no-worry option for anyone who wants to expand their console storage without thinking too hard about compatibility. This 4TB model sits at the top of the capacity chart for PS5-ready drives, and it comes with a heatsink that's been designed specifically for the PS5's M.2 slot. You pop it in, put the cover back on, and you're done. No measuring, no aftermarket heatsink hunting, no thermal anxiety.

Who's this for? Honestly, it's for the person who has a PS5 with the standard 825GB of usable storage and is tired of deleting games every time a new Call of Duty update drops. 4TB is enough to hold roughly 100 games, depending on what you play, and that's a genuine quality-of-life upgrade. It's also a solid pick for PC builders who want a fast Gen4 drive with a heatsink already attached, though the PS5 branding means you're paying a bit for the license.

What makes it interesting is the combination of speed, endurance, and that official license. The read speed hits 7,300 MB/s, which is right at the top of what PCIe Gen4 can do. The endurance rating of 2,400 TBW is well above average for a consumer drive. And the social proof is basically off the charts, sitting in the 100th percentile in our database. People buy this thing, use it, and come back happy. That's rare for any product category.

If you're a PC builder who doesn't own a PS5, skip this and grab the WD_BLACK SN850X or the Kingston FURY Renegade G5 instead. You'll get essentially the same performance without paying for the PlayStation license. The heatsink is also shaped for the PS5's slot, so it's not the best fit for every motherboard layout. If you're on a tight budget, this drive is a hard pass. The 9th percentile affordability ranking means you're paying a premium for convenience and branding. A 2TB drive from Crucial or Kingston will cost significantly less and still hold a healthy game library. And if you need portable storage, look elsewhere entirely. This is an internal drive, and its portable use case score of 24.5 out of 100 reflects that. For external backups or moving files between machines, a portable SSD or even a fast USB drive makes way more sense.

If you have a PS5 and you're tired of managing storage, this is the drive to buy. The 4TB capacity means you can install basically everything you own and still have room for the next year of releases. The official license means you don't have to worry about whether the heatsink fits or whether the drive meets Sony's speed requirements. It just works, and it works fast. The 4.9-star customer rating across 710 reviews backs that up.

For PC users, the calculus is different. The SN850P is a great drive, but you're paying for PS5 branding you don't need. The Kingston FURY Renegade G5 or even the non-PS5 version of the SN850X will give you essentially the same performance for less money. That said, if you find this drive on sale at the lower end of the price range, it's absolutely worth grabbing. The endurance rating alone makes it a solid long-term investment for a gaming rig or a workstation that sees heavy write loads.
