The Kingston NV2 is a huge improvement over the NV1. It comes at similar pricing but is significantly faster. Thanks to the new Phison E21 controller, the drive offers the highly popular PCIe 4.0 capability at only $80 for the 1 TB version, making it a great choice for any cost-optimized system.

Thanks for the review.

I don't know about the NV2.....I can get the Mega Fastro MS200 with DRAM cache for around €130 on sale in DE with DRAM. Yeah, that brand is not known well in the EU, but compared to NV2.....

Components not guaranteed. Kingston in a nutshell.

Bought three V300 series sata ssd models once all three failed inside of 6months never bought from them again after that, that series of drives where plagued with async nand modules

This drive is €75 for 1 TB. MS200 seems to be PCIe 3.0 using SM2262, so same as HP EX900 and ADATA SX8200 Pro, so similar performance as NV2

It does have DRAM, NV2 does not. ;)

I do have a MS200 in my LAN-PC. Could provide it for testing after the LAN. That's a quick & dirty CDM run from mydealz:

It would be great if you could measure the size of the pseudo-SLC cache once again when the drive is 80% full. Is it as large as physically possible (so ~66 GB) or is it at 20% of 88 GB (so ~18 GB)? Or something else?

I think that there must be some technical reason, not just product segmentation, to limit the pSLC cache and not let it expand over the entire flash memory. Maybe it's because of controller limits (small internal RAM etc.) or related to the size of the host memory buffer. Phison's blog gives a small hint:
But DRAM-less SSDs aren’t exactly a “one-size-fits-all” solution either. The performance of DRAM-less SSDs generally suffers due to innate deficiencies in the caching space reserved for intermediate data and mapping tables.

NV1 vs NV2 is another shining example of why QLC is an unflushable turd.

The only way you can make it not horrible is to spend the money on DRAM cache, then allocate a lot of pSLC and overprovision it hard. That hurts its value proposition enough to make it untenable, which is why I just completely avoid QLC at any cost, for any reason, at all times and the rest of humanity would be doing themselves a favour if they followed my example. The sooner QLC dies due to lack of economic viability, the better, IMO.

Filling the whole 1 TB capacity completed at 620 GB/s average, a good result,

I tried to quote you @W1zzard but the forum blocks me, so hopefully you see this.

Given Kingston is notorious for bait and switch(along with AData and WD), would like to see a follow up of this drive few months later with a retail SKU.

I got burned about it so many times, I simply black listed them. What's the point of the shiny reviews W1z does that in store I get a completely different SKU? And hey usually an underperforming one.

DRAMless isn't as bad as it was in years past.
Yeah, controller vendors have been working on this for years, it's their highest priority.

NV1 vs NV2 is another shining example of why QLC is an unflushable turd.

The only way you can make it not horrible is to spend the money on DRAM cache, then allocate a lot of pSLC and overprovision it hard. That hurts its value proposition enough to make it untenable, which is why I just completely avoid QLC at any cost, for any reason, at all times and the rest of humanity would be doing themselves a favour if they followed my example. The sooner QLC dies due to lack of economic viability, the better, IMO.
Honest curiosity: Why does it matter to a consumer who has no emotional attachment to a particular technology or an equally emotional stance against one? In the machine I'm currently using I have two Intel 660p 1TB drives - those horrible, life destroying, first generation QLC drives, universally hated and warned against by the "enthusiast" tribe. Even more horrifyingly, one of them is an OS drive with some games on it, the other has mixed data, with both being more than 80% utilized. If the tribe is half-correct, by this time my cat should be dead, my wife pregnant with another man and I should have no less than two more debilitating diseases than I have now.
In other words: Would changing to proper, five times more expensive, community-accepted, "enthusiast" devices make my life better? Or, at least, make my OS boot significantly faster than 15 seconds it takes now, games load instantly, browser start in less than a second it takes currently? Would I actually see any difference outside of synthetic benchmarks which I dare not to spend my whole days running?

I believe SSDs are far into the realm of rapidly diminishing results. Even in this test differences between cheapest and most expensive drives are imperceptible to anyone other than obsessive types running benchmarks in a loop since the moment they open their eyes.

Well that's the SKU at your local store from your distribution channel, there are absolutely no guarantees I would get the same in mine, not mentioning even after few months as it was reviewed. They source stuff from anywhere and anyone.

That's life with those type of companies. You have to keep in mind that always picking up their products.

Perfect candidate based on endurance rating for a future Ninja switch to QLC TRASH flash. None really wants QLC for the same price as TLC, those ssd's only make sense for super big 4/6/8TB drives or when discounted. (1TB/40€) Kingston are the kings of nand flash switch since the compressed days of Sandforce controllers. Kioxia exceria, intenso premium nvme and some teamgroup models are cheap examples of TLC that can be found for ~60€ on the EU market. The competition is really tough and the QLC ones (NV1,P1,P2,660P) are pointless. Lets hope for a pure $/TB/TBW/Warranty review in the future.

Yeah ... that's why they put such a low endurance rating, so they can go QLC later. It still won't matter, you're not writing that much data

TLC that can be found for ~60€ on the EU market
These are Gen3 though. The NV2 is the cheapest Gen 4 drive on the market right now (which of course is Kingston's strategy)

Not much advantage over Gen3 ... except of course in cases where you can only give it 1 or 2 PCIe lanes to use.

The most important reason to not recommend a QLC drive is not the performance or (stated) TBW. It's the general perception (and I don't object to it) that they are low quality and low reliability products, being ahead of everything else in the race to the bottom.

As for your 660p's, if they work fine for you then fine. It's not like most of them will die in a couple years. But Storage Review tested it and found that "the 660p puts up large block sequential reads of 225MB/s and writes of 77MB/s". For me that's unacceptable because my 80GB Intel X25-M G2 from 2008, with a 3 Gb/s SATA interface, which is a good fit for my old Core 2 Duo PC, reads at 250 MB/s and writes at 70 MB/s as well.

Five times more expensive? What FUD and nonsense are you talking about?! - Decent "Editor's Choice Award" TLC drives are NOT more expensive: This NV2 and the excellent SN570 are both the same cost/TB as the QLC NAND options:

1663759159943.png


Or, at least, make my OS boot significantly faster than 15 seconds it takes now, games load instantly, browser start in less than a second it takes currently?
Not one of those three things is sensitive to the NAND used, or in fact particularly storage-bottlenecked - which is why even 235MB/s SATA2 SSDs are barely any slower in those three scenarios. Either IOPS, software wait timers, or CPU/RAM decompression and operations dominate the time all of those tasks take. If you don't need to write data, then you don't need to care about performance, only reliability and price, in which case QLC has historically been reliable enough, but with a measurably lower lifespan, and still costs just as much as faster, higher-endurance options. I'm not saying QLC will ruin that experience, but even as an extremely light, consumer workload with zero signiricant write requirements, you're still giving up both endurance and write performance for free. Why? Will the next person who gets your PC also have the same requirements as you, or will they be disappointed that moving large files for archive/video editing/indexing/collation absolutely sucks on your drive?

If you were offered a good, fast, fun, long-lasting, reliable car for the exact same price as an acceptable, highway-speed-capable, boring, short-lived (but still as reliable) car - which one would you pick? You don't care about fun or driving faster than highway speeds, holding onto it for decades, or resale value? Then fine - it makes no difference if you genuinely have no concern about all the caveats.

Even in this test differences between cheapest and most expensive drives are imperceptible to anyone other than obsessive types running benchmarks in a loop since the moment they open their eyes.
Did you even read the review? it's 4x faster than the QLC NV1 - that's not 'imperceptible to anyone' and copying large files is something a lot of people do. Maybe not daily, but having to wait four minutes instead of one minute every single time quickly gets tiresome if you do any amount of it more than once in a blue moon:

1663760145767.png 1663760195131.png

Further to that, the software installations and just general search/indexing performance of identically-priced TLC drives like the SN570 or NV2 can be anywhere from 20-50% faster in a huge range of everyday tasks. Photoshop and Premiere performance are night-and-day different.

I get it, you just boot your PC and game/browse and the inferior QLC drives are just fine for that. Not everyone has such a limited demand of their storage, and the bit that irks me about QLC is that it absolutely sucks for people who do need the performance, yet manufacturers are taking the cost savings and failing to pass them onto the consumer. If slower QLC drives were much cheaper than TLC, I'd have a different stance, but they're not. They're provably worse in almost every measurable way and still cost just as much as the objectively better hardware.
