Lexar NQ780 4 TB NVMe SSD review

Alright, I'll come out and say it, the Lexar NQ780 is a bit average. A bit dull. Usually, when it comes to reviewing hardware like this, particularly SSDs, there's always something to write about. Something that's slightly interesting, or some weird quirk that the manufacturer has tweaked a certain way that's led to some curious performance metric in one manner or another. With the NQ780, though, that's kind of not the case.

It's interesting, sort of, in its own way, because it's not really that interesting. In a world of blisteringly quick PCIe 5.0 drives like the SN8100, intuitive new controller designs, limit-breaking NAND flash technologies with a quadrillion layers up-down, left and right, the NQ780 just kind of exists.

This isn't the best SSD of 2025, not by a long shot. It performs and delivers speed in the same manner that the Samsung 990 Evo Plus did when I reviewed that back in October of 2024, or the Crucial P310 did in January of this year. And it's aimed at that market too. It's a budget solution for those more interested in cheap capacity over speed and load times. It's not particularly awful, it's just outpaced or on par with practically every other PCIe 4.0 drive that's come before it, and it's done this around eight months late to the party.

Its biggest advantage is its pricing, and, although I'm writing this review in the midst of the carnage that is November (thanks, Black Friday), Lexar's aggressive RRP gives the NQ780 one hell of an affordability score. Namely, it's $0.07 per GB in the US and £0.06 per GB in ol' Blighty. With updated pricing across my benchmark database, that is one of if not the lowest price per gig I've seen to date. If it stays that way (a lot of drives are increasing in price right now due to the ongoing memory crunch, that might be its saving grace).

So, now we've got that one interesting element out of the way, let me bore you with the remarkably mundane hardware situation we're looking at here. The NQ780's a bit of an oddity in its component setup. There's no Phison, Maxiotek, Silicon Motion, or Sandisk controllers here; instead, we're greeted with an Innogrit IG5236 eight-channel 12 nm controller, which was initially launched waaaay back in 2020. It's all based on the PCIe 4.0 platform, M.2-2280 form factor, and it's been paired with a stack of Intel's 144-layer QLC NAND flash, which taps out at 1 TB packages. That means for this 4 TB model, we've got four on a single-sided stick (keeping in line with modern trends, making it compatible with many a laptop, console, PC, etc).

That should tell you straight away, then two things. Firstly, it's slightly toastier than most modern drives, and slightly less efficient as well, and secondly, that's a lot of old hardware trundling along in its sultry snazzy stickered form, and you'd be right. This almost feels like a stock clear-out and rebrand rather than a new release, particularly given how old that controller is.

Unfortunately, then, as you may or may not be surprised to hear, performance is what you'd expect from an SSD of this caliber. Although sequentials are initially high, once that pSLC cache fills up, she slows to a crawl.

CrystalDiskMark measured seq read and write at 7,446 MB/s and 6,601 MB/s, respectively, which puts it on par with the likes of the WD Blue SN5100. Not a bad showing by any means, but drop down to some Random 4K testing, and the battle quickly shifts. The SN5100 dominates the NQ780, registering 107 MB/s on the write, versus the NQ780's paltry 70 MB/s. That figure is actually far worse than at first glance, too, as it makes the NQ780 joint second to last on that metric, across all of the 19 drives I've tested in the last 12 months. Out of 19 drives, it came 17th…

That's important because random 4K read performance is incredibly critical for us gamers, as it's generally comparable with how AAA titles read files on an SSD. Think of it like a CPU pulling a game asset from here, a texture file from there, a mesh from over yonder, audio lines from that place, and you're on the right lines. These assets aren't stored linearly (or sequentially) like with photos or videos, and the NQ780's poor showing here translates into our game load test times as expected.

Final Fantasy's XIV Shadowbrings benchmark chugs along at a staggeringly slow 7.869 seconds on average. Which, although again relatively quick in real-world terms, pales in comparison to its modern SSD competition. That's particularly damning as well, given FF XIV tends to favour drives with a larger capacity, and I am testing the 4 TB model here, whereas most of our results come from 2 TB models.

This thing confuses me. It almost feels like someone let an AI LLM make a business decision here. It spotted a load of cheap NAND, some budget controllers from yesteryear at a bargain price, and slapped it all together for a quick, rapid launch of a drive that just can't quite keep up with its modern 4.0 equivalents.

It's biggest advantage comes in the form of that pricing being as aggressive as it is, but I can't help but shake the feeling that you'd be far better off investing in the additional performance found in those alternatives, the SN5100, for example, has gone for only a little more (though it is now priced much higher, gah), yet delivers exemplary performance in every category by comparison, even with QLC NAND as well. You can just do so much better, and that's a problem. Releasing a drive like this today is just not enough, but industry-wide price increases might keep it in play (if it stays at this sorta price for long).
