WD Black SN850P review: one to grab on sale

WD Black SN850P: One-minute review

As a big proponent of the WD Black SN850, I can’t deny that I’m a little disappointed with the WD Black SN850P. Although faster on paper, I found that the real-world performance of the SN850P actually lags behind that of the older SN850 – even scoring slightly lower in the PS5‘s internal storage benchmark. The design has taken a bit of a step back this time around too, as the SN850P ditches the cool, though admittedly slightly impractical, LED of its predecessor in favor of a much plainer, and presumably cheaper to manufacture, look.

This wouldn’t be a huge issue, but the SN850P comes in a little more expensive than not only the SN850 but also some of the best SSDs for PS5. When officially licensed alternatives like the Seagate Game Drive M.2 SSD for PS5 can be found cheaper and will run a bit better, there’s no real reason to pick up the SN850P above the rest. That is unless you manage to find the 1TB or 2TB models on one of their fairly regular discounts, where price cuts of up to $50 / £30 make these products much more competitive.

There are also the larger capacity variants to consider. Seagate’s licensed drive doesn’t come in capacities above 2TB, so the SN850P is one of the only options if you want to keep things official at that size. The 8TB variant is also one of the few 8TB PS5 SSDs on the market right now from a major brand and is quite reasonably priced for what it is. If it’s either of these versions that you were considering, add half a star to the score above.

Otherwise, the WD Black SN850P is underwhelming on the whole. It’s a fine PS5 SSD that, thanks to its slightly overambitious price tag, fails to stand out.

WD Black SN850P: Price and availability

• 1TB is $119.99 / £107.99
• 2TB is $189.99 / £184.99
• 4TB is $319.99 / £329.99
• 8TB is $749.99 / £705.99

The 1TB WD Black SN850P retails for $119.99 / £107.99, though can be found hovering slightly below that price at online storefronts such as Amazon. The 2TB costs $189.99 / £184.99, though again you can expect to pay a little less if you buy online.

Outside of sales, both these models cost a bit more than the Seagate Game Drive M.2 SSD for PS5 equivalents (the 1TB model goes for $99.99 / £99.90 while 2TB is $159.99 / £159.90) – again, a drive that performed slightly better in my testing.

The cost then increases substantially as you move towards the 4TB model, which is $319.99 / £329.99, or 8TB, which goes for a massive $749.99 / £705.99. Although the most recent arrival, the 8TB has already started receiving discounts of about $50 / £50 that put the price in line with most other 8TB PS5 compatible SSDs making it a solid option if you can afford it.

WD Black SN850P: Specs

WD Black SN850P: Design and features

• Design is a step down from the SN850
• Heatsink included out of the box
• 5-year limited warranty

The design of the WD Black SN850P is, in my opinion, a step down from the SN850. It’s got a similar overall look, with a sleek black heatsink constructed from a very robust feeling metal but lacks the little LED that was on top of the SN850. This was never a huge selling point, after all, you can’t exactly see it when it’s been inserted inside a PS5. But it still makes for an SSD that looks a bit cheaper on the whole.

Otherwise, you have the same white WD Black branding, plus a little label stating the name of the product. One noticeable departure is the introduction of a white PlayStation logo on the right-hand side, which matches everything nicely.

Although it looks very similar from a distance, the heatsink has actually been redesigned with a slightly different shape and a few more gaps for dispersing heat. Given that I never experienced any noticeable thermal throttling on the SN850, I can’t say that this seems necessary but it definitely doesn’t hurt. It also fits perfectly in the PS5 or PS5 Pro.

In the box, you get the SSD in a little clamshell package, in addition to some warranty and service information. You’re covered by a five-year limited warranty here, which does offer some peace of mind and means that this drive will likely see you through the rest of the PS5’s life if you opt to get one.

WD Black SN850P: Performance

• Performance could be better for the price
• Initial benchmark score was very poor
• Reasonable results in real-world tests

When I first inserted the WD Black SN850P, the PS5’s internal benchmark measured it as a shockingly low 5,966 MB/s. This is still above the recommended SSD specs for the console, but nowhere near the advertised 7,300 MB/s or really what you would reasonably expect from a drive at this price. Luckily, when I reformatted the drive and ran the test again a little later it scored a more reasonable 6,338 MB/s so I’ll chalk that first number up to chance.

This second figure was still lower than I wanted, though, as the SN850, which is actually advertised with a 7,000 MB/s read speed, achieves figures in the 6,400 MB/s range on my machine. It also puts this behind the Seagate Game Drive M.2 SSD for PS5, which recorded 6,459 MB/s.

Thankfully, the WD Black SN850P did fairly well in a series of real-world tests. Moving to the drive from the PS5’s internal storage, a 23.24GB copy of Vampire the Masquerade: Swansong was copied in just 12.61 seconds. A 33.35GB installation of Lords of the Fallen then took 15.89 seconds, while a 45.98GB installation of The Crew Motorfest took 21.02 seconds.

Testing some larger files, 101.9GB of Far Cry 6 took 43.74 seconds to copy while a selection of multiple games totalling 226.9GB copied in 3 minutes and 14 seconds. These figures are all adequate and not more than a few seconds behind equivalent transfers on the Seagate Game Drive M.2 SSD for PS5.

Copying back to the PS5, the 21.30GB Granblue Fantasy Versus: Rising was ready to play in 1 minute 27 seconds, while Stellar Blade, which is 32.41GB, took 2 minutes and 15 seconds. Finally, the 38.34GB Tiny Tina’s Wonderlands copied back in 2 minutes and 34 seconds. These figures are all perfectly adequate, and realistically more dependent on the PS5’s internal write speed than anything else.

Ultimately, you’re not going to run into any performance problems using the WD Black SN850P. Every game I tested was smooth, with decent loading times and no noticeable slowdown. Just bear in mind that, unless you buy on sale, you can get drives with more oomph for the price.

How I tested the Seagate Game Drive M.2 SSD for PS5

• Used as primary PS5 SSD
• Tested over the course of a week
• Tested with a range of titles

I tested the WD Black SN850P over the course of a week, using it as my primary PS5 SSD drive and playing a wide variety of games from it. During my time with the drive, I was careful to look for any noticeable impacts on performance compared to the console’s internal storage.

I also assessed the drive’s performance using the built-in PS5 storage benchmark and by copying a large library of games in order to measure the time taken. I compared my experience to my hands-on testing of other PS5 SSD models including the Samsung 990 Pro, WD Black SN850, Seagate Game Drive M.2 SSD for PS5, and more.
