WD Black SN770 review: just short of SSD greatness


Western Digital are persevering with their cost into high-speed PCIe 4.0 SSDs with the WD Black SN770. That is fairly straight down the center so far as Gen 4 SSDs go: the 1TB mannequin I’ve examined claims sequential speeds as much as 5150MB/s for reads and 4900MB/s for writes, sufficient to embarrass any PCIe 3.0 SSD with out veering into mega-enthusiast territory. There’s a broad vary of capacities too, beginning at 250GB and ending at a roomy 2TB.


All superb to date – not each little shard of PCIe 4.0 storage must be an formidable tempo service provider like WD’s personal Black SN850, nor a comparatively entry-level drive just like the Black SN750 SE. Nonetheless, whereas the Black SN770 can ship on in-game efficiency, its general efficiency and surprisingly excessive pricing leaves it caught awkwardly between these two different WD choices. And given they’re two of the most effective SSDs you should purchase proper now, that’s not a really snug place to be.


Nonetheless, let’s begin with the great half. The Black SN770 could be blazingly quick in the proper situations, together with when loading video games. Shadow of the Tomb Raider’s Cozumel mission loaded from the Black SN770 in a scant 9.39 seconds, a full second sooner than the Black SN750 SE and even a few blinks sooner than the Black SN850. It additionally posted a superb write velocity outcome, 3352MB/s, in CrystalDiskMark’s 8 queue/8 thread random benchmark. That’s sooner than each of its WD stablemates in addition to the Samsung 980 Professional, one other higher-end PCIe 4.0 SSD. Its 236.6MB/s outcome within the AS SSD 4K write take a look at can also be one of many highest I’ve received on report.


Good write speeds have their makes use of, particularly when copying recordsdata, and also you’d in all probability be doing a whole lot of that when putting in a brand new SSD. Sadly, the Black SN770’s learn speeds aren’t on the identical stage. Again within the CrystalDiskMark take a look at, its learn velocity results of 2516MB/s isn’t dangerous per se, but it surely’s slower than the Black SN850’s 2614.5MB/s and the 2695MB/s of the Kingston Fury Renegade. And it appeared to wrestle with AS SSD’s random 4K learn take a look at, solely managing 54.2MB/s. That’s really one of many lowest we’ve seen from a PCIe 4.0 drive, with even some PCIe 3.0 SSDs just like the Kingston KC2500 and Samsung 970 Professional outpacing it, to not point out the seemingly lower-spec Black SN750 SE.


Not that you simply’d actually see sequential learn/write speeds in bizarre use, however the Black SN770’s ends in the AS SSD 1GB sequential exams turned out on the decrease facet too. With a 3924.9MB/s learn velocity and a 3995.8MB/s write velocity, it’s sooner than the Black SN750 SE, however the Black SN850 beats it by over 2000MB/s on reads and almost 1200MB/s on writes.


The factor is, these outcomes would not be a problem in and of themselves. The Black SN770 could also be inconsistent however most of the time, it’s quick, and that Shadow of the Tomb Raider loading velocity reveals it might probably compete on gaming efficiency. The Black SN770 may have slotted in far more neatly between the Black SN750 SE and the Black SN850, and amongst PCIe 4.0 SSDs on the whole – all it could have taken was the proper pricing.


It doesn’t have the proper pricing. Not for the extra capacious fashions anyway. The 1TB model is launching at £144 / $130, which right here in Blighty is about £20 greater than the 1TB Black SN850, £40 greater than the 1TB Black SN750 SE and £14 greater than the Samsung 980 Professional at their respective (and present) finest costs. Then there’s the 2TB model of the Black SN770, which is round £80 greater than the equal Black SN850 and 980 Professional SSDs.

The WD Black SN770 SSD next to the WD Black SN750 SE.


I do know I mentioned, actually yesterday, that it may be price investing in dear storage. And the Kingston Fury Renegade is definitely not cheaper than the Black SN770, however in return to your outlay, it does will get you a few of the finest learn/write speeds in the marketplace. The Black SN770 could have flashes of brilliance, but it surely’s not persistently speedy sufficient to justify over its personal greater brother, the Black SN850.


There’s one doable exception within the 250GB mannequin, and never simply because the Black SN850 lacks certainly one of its personal. In actual fact, 250GB variants of PCIe 4.0 drives aren’t all that frequent on the whole, and at £56 it’s solely £5 greater than the 250GB Black SN750 SE. It may due to this fact be an honest decide for anybody wanting PCIe 4.0 efficiency, however solely has the finances for a small SSD + giant HDD storage setup.
