2022 has had its PC {hardware} disappointments, but it surely’s been a classic yr for gaming SSDs. In the latter half alone we’ve seen the top-class PCIe 3.0 speeds of the Crucial P3, the stunning affordability of the PCIe 4.0-based Crucial P3 Plus, the excellent premium-tier efficiency of the WD Black SN850X, and now the Samsung 990 Pro: an NVMe SSD with the quickest learn speeds within the land. So say its makers, anyway.
On paper, the 990 Pro fortunately makes greater claims than these of its closest rival, the Black SN850X. That most learn pace? 7450MB/s for Samsung, 7300MB/s for WD. Write speeds additionally seem to favour the 990 Pro, with a claimed 6900MB/s to the Black SN850X’s 6300MB/s. Samsung are asking loads with their drive’s pricing, beginning at £160 / $170 for the 1TB mannequin, however then it’s probably exploring new heights of what a PCIe 4.0 SSD can do. And why not – PCIe 5.0 SSDs are nonetheless a methods off.
Despite this ambition, although, it was the Black SN850X that got here out on prime in AS SSD’s sequential assessments. These purpose to document the very highest learn/write speeds you may really get in an unusually simple workload, and whereas neither of those high-end SSDs really reached their marketed maximums, the 990 Pro’s 5435MB/s sequential learn pace end result fell behind the Black SN850X’s 5715MB/s. The latter gained out on sequential write speeds too, with the 990 Pro producing 5349MB/s. That’s in any other case glorious, however not as excessive because the SN850X’s 5701MB/s.
All that hype for nowt, then? Maybe not. Sequential outcomes make for impressively massive numbers however they seldom symbolize an SSD’s on a regular basis efficiency, and in our more durable, non-sequential benchmarks, the 990 Pro asserted itself extra firmly. Crucially, it did so particularly on learn speeds, that are way more essential to games as they’ll what impacts loading instances and texture streaming efficiency.
In CrystalDiskMark’s random 4K benchmark, the Black SN850X recorded a 3187MB/s learn pace. That can be one for our document books, had been it not for the 990 Pro, which thrashed it with 3647MB/s. Granted, the 990 Pro’s write pace of 4090MB/s was in flip crushed by the Black SN850X’s 4261MB/s, however moreover the margin of victory being significantly narrower, write speeds aren’t practically as helpful to games particularly.
This was obvious in Shadow of the Tomb Raider, the place the 990 Pro took a median of 6.6s to load a scene heaving with NPCs. The Black SN850X took 6.7s on common, which isn’t a lot of a distinction, however then the Samsung SSD was persistently quicker throughout all three measurement runs. It additionally cuts that loading time (roughly) in half in contrast the earlier Samsung 980 Pro, and that SSD was a little bit of a pace addict in its personal proper.
It’s not simply advertising bumf, then: the 990 Pro actually is the quickest PCIe 4.0 SSD for learn speeds, each in principle and follow. The Black SN850X is extra of a well-balanced drive, with invariably increased write speeds that may very well be helpful should you repeatedly have to shift round massive information, however I’m guessing you’re not on RPS for workstation constructing recommendation. Games are virtually all about reads, and the 990 Pro is efficiently superlative for them.
However, at this second in time, it’s nonetheless the Black SN850X that’s the higher purchase – even when this comes right down to the straightforward matter of chilly, arduous money. Whereas the 990 Pro has simply launched, all dressed up with the premium pricing anticipated of a class-leader, the Black SN850X is presently out parting within the Black Friday gross sales. The end result? A 2TB Black SN850X prices, within the UK, the identical as a 1TB 990 Pro. And you’ll be able to examine fractions of seconds in game loading instances all you need, however that arithmetic simply doesn’t work for Samsung.
In the long run, thoughts you, I’d count on the choice to get a lot more durable. Besides Black Friday season ending in a matter of days, it appears unlikely that the Black SN850X will get less expensive, whereas the 990 Pro’s pricing can solely go down from right here. I sort of hope that’s the case, anyway – the 990 Pro is simply too rattling quick to deserve second place.
