2022 has had its PC {hardware} disappointments, nevertheless it’s been a classic 12 months for gaming SSDs. Within the latter half alone we’ve seen the top-class PCIe 3.0 speeds of the Essential P3, the stunning affordability of the PCIe 4.0-based Essential P3 Plus, the excellent premium-tier efficiency of the WD Black SN850X, and now the Samsung 990 Professional: an NVMe SSD with the quickest learn speeds within the land. So say its makers, anyway.


On paper, the 990 Professional fortunately makes larger claims than these of its closest rival, the Black SN850X. That most learn velocity? 7450MB/s for Samsung, 7300MB/s for WD. Write speeds additionally seem to favour the 990 Professional, 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 doubtlessly exploring new heights of what a PCIe 4.0 SSD can do. And why not – PCIe 5.0 SSDs are nonetheless a methods off.

I undertand that Sonic, not in contrast to the Samsung 990 Professional, is compelled to go quick.


Regardless of this ambition, although, it was the Black SN850X that got here out on high in AS SSD’s sequential exams. These goal to file the very highest learn/write speeds you would possibly really get in an unusually simple workload, and whereas neither of those high-end SSDs really reached their marketed maximums, the 990 Professional’s 5435MB/s sequential learn velocity outcome fell behind the Black SN850X’s 5715MB/s. The latter gained out on sequential write speeds too, with the 990 Professional 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? Possibly not. Sequential outcomes make for impressively massive numbers however they seldom characterize an SSD’s on a regular basis efficiency, and in our harder, non-sequential benchmarks, the 990 Professional asserted itself extra firmly. Crucially, it did so particularly on learn speeds, that are way more essential to video games as they’ll what impacts loading occasions and texture streaming efficiency.


In CrystalDiskMark’s random 4K benchmark, the Black SN850X recorded a 3187MB/s learn velocity. That may be one for our file books, have been it not for the 990 Professional, which thrashed it with 3647MB/s. Granted, the 990 Professional’s write velocity 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 almost as helpful to video games particularly.


This was obvious in Shadow of the Tomb Raider, the place the 990 Professional took a mean 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 sooner throughout all three measurement runs. It additionally cuts that loading time (roughly) in half in contrast the earlier Samsung 980 Professional, and that SSD was a little bit of a velocity addict in its personal proper.

The Samsung 990 Pro SSD.


It is not simply advertising bumf, then: the 990 Professional actually is the quickest PCIe 4.0 SSD for learn speeds, each in principle and apply. The Black SN850X is extra of a well-balanced drive, with invariably larger write speeds that could possibly be helpful should you frequently must shift round massive recordsdata, however I’m guessing you’re not on RPS for workstation constructing recommendation. Video games are nearly all about reads, and the 990 Professional is efficiently superlative for them.


Nevertheless, 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, exhausting money. Whereas the 990 Professional has simply launched, all dressed up with the premium pricing anticipated of a class-leader, the Black SN850X is at the moment out parting within the Black Friday gross sales. The outcome? A 2TB Black SN850X prices, within the UK, the identical as a 1TB 990 Professional. And you’ll examine fractions of seconds in sport loading occasions all you need, however that arithmetic simply doesn’t work for Samsung.


Sooner or later, thoughts you, I’d count on the choice to get a lot harder. Apart from Black Friday season ending in a matter of days, it appears unlikely that the Black SN850X will get less expensive, whereas the 990 Professional’s pricing can solely go down from right here. I type of hope that’s the case, anyway – the 990 Professional is simply too rattling quick to deserve second place.
