QLC + HMB (No Dram), not the full story though as this drive actually outperforms the 980 pro in pcmark and gaming loading tests https://hothardware.com/reviews/solidigm-p41-plus-nvme-ssd-r…

What’s the consequence of no DRAM?
https://hothardware.com/reviews/solidigm-p41-plus-nvme-ssd-r…
This seems to show the consequences of no DRAM
Yeah, in tests where DRAM matters, Samsung 980 Pro is 7x faster.
Though in general usage, most people probably won't encounter those situations where lack of DRAM really hampers the performance.
The review you quoted has some issues, especially around 980 Pro's performance.
In one chart, I can see it is simply wrong. Given 980 Pro beats P41 Plus in all 3 game tests, why is the final average lower? In sustained write, there is no contest. Don't try to trick people into thinking this is better than 980 Pro.
Honestly, unless you are huge fan of QLC SSDs, I really don't get why you would want to get this at this price.
It's literally just 3Dmarks gaming benchmarks which is quite good, and pcmark does score this drive higher than a 980 pro not trying to trick anyone.
That particular review is slight unbalanced. While it is fine to compare it to 980 Pro, compared it to other reviews, I am noticing the PCMark tests chosen seems a bit too deliberate in that review. All the ones where 980 Pro wins by a large margin is omitted. Choosing Quick Benchmark tests give DRAMless SSDs an advantage. It is known that some DRAMless SSDs do struggle in consistency tests.
All the reviews so far are somewhat limited.

It is interesting that all the new gen PCIe gen 4 DRAMless revised 4 channels controllers are doing well in some of the benchmarks. WD Black SN850X 2TB was $273.54. SN770 2TB is $263.15 (without the bookmark hack 5% extra discount). I guess people will need to decide whether it is worthwhile to go for a quality QLC PCIe gen 4 DRAMless NVMe SSD.
$240 for d-ramless, that’s not that great imo
It seems gonna be a trend for many of the budget PCIe 4 NVMe drives will be DRAMless+HMB as most reasonable amount of writes will be either absorbed by the flash interface itself (it's getting really fast now) or SLC cache.
The main thing is the most recent batch of PCIe gen 4 controllers, and the combination of the latest 3D NAND (more layers) can really trick benchmarks and do perform well in quite a few common tasks (inc. gaming). WD and Samsung did that on SN850X and 990 Pro, but Phison and Silicon Motion released new PCIe gen 4 low end controllers.
Not sure what Intel did (this is basically an Intel QLC SSD, even though it is now owned by SK Hynix) but its sustained write is impressive for QLC. It also has really fast SLC cache recovery (so whether we are seeing true QLC speed or it is still some SLC cache into the mix is unclear). However, with fast SLC cache recovery, the QLC write speed cannot be too slow. Why other makers have not been able to achieve this 200% improvement on 2TB QLC is puzzling.
However, without seeing the test when the SSD is 80% filled, we are not able to see 100% true QLC write. Regardless, given high end PCIe gen 4 SSDs are overkill. If we close a blind eye on consistency test results (let's face it, we are not going to be doing heaps of mixed read and write on an SSD for a hour normally), at what point do we start accepting these?
I read reports that claim it's mainly due to the better fabbed controllers and flash interface speed, no matter it's TLC or QLC.
YMTC's 128-layer NANDs are showing promising out-of-cache speed, just imagine their 232-layer product in the near future as well as similar stuff from other manufacturers.
All things considered as long as a SSD is from valid brands endurance shouldn't be a major issue for the vast majority of users, rather performance should be prioritised when bidding.
@xmagic: It's getting more complicated to objectively evaluate SSDs, especially with the up coming 232L NAND (for PCIe gen 5). 4K random read QD1 doesn't look like improving much, but the random write looks like taking another leap. It will be interesting to see how SSD makers try to sell us better SLC cache write speed.
TBW is not an objective measurement of endurance. Whether you used 50% or 80% of the SSD affects the endurance. Another factor is price. While this SSD is quite interesting despite being QLC, it is priced quite high for QLC. All these hype about 232L NAND, the reality is PCIe gen 5 SSDs won't be cheap. Not to mention there will be multiple iterations of PCIe gen 5 controllers. Later on, 16 channels QLC setup (PCIe gen 5) is really going to make the whole thing even more confusing.
@netsurfer: Luckily for most normal users it just doesn't matter.
If you just want an SSD to fill with Steam games for example, then any old drive is absolutely fine.
You don't need to know the details unless you have some very specific use cases, and in this scenario you'll usually know what you need.
@Nom: Yeah, and that explains why this deal has fairly low positive votes. It's not cheap in terms of $/GB and it is not that great performance wise. A quality QLC SSD isn't that appealing.
Remove the "ig" from Solidigm and replace it with a "b" and you have a more marketable name.
is this made by SK hynix ?
