The Solidigm P44 Pro is the company's new PCIe 4.0 flagship M.2 NVMe SSD. It is built using the blazing fast Hynix ACNS075 controller paired with 176-layer 3D TLC NAND. In our review we saw impressive performance numbers, making the P44 Pro the fastest SSD we ever tested.

Kind of sad seeing those tests where everything is relatively close e.g. minor real world improvement between this and a Crucial 2.5” 500 from yesteryear. Is this due to the limited real estate of the M.2 form factor for engineers, or do we have to wait another decade or two for a fundamentally different memory technology?

The same hardware as SK hynix Platinum P41?





The upper is from SK hynix, the lower is from Solidigm. Both are 2TB models.
Just the SAME!

Seems like it. Results indicate slightly different firmware though

The thing is that real software doesn't scale with infinitely fast storage. That's why synthetics or traces are useless for benchmarking in my opinion. When a block is read some operation is performed on it, which takes time on the CPU, so you're rarely ever fully loading your storage subsystem, or only for a short moment.

Yes, the firmwares are not the same: the 2TB model from Solidigm is 2048GBs, and the one from SK Hynix is 2000GBs.

This drive is not infinitely fast. It still has the drawback of all modern SSDs - low random read/write speeds.
RAM disks are much better.

Thank you for the review. Interesting product to compare with others before any considerations. To me the SK Ps Gold and Platinum are better performers for the price.

One thing that I've seen happening in other drives review is the price section error. By simply adding the drive capacity (bold red below) next to the price and inputting the correct price per TB or GB (when applicable), it would make it clearer for the average reader to understand the overall cost.

2TB $235 / $117.5 per TB
1TB $130 / $130 per TB

You're already running into diminishing returns once you push into high-end NAND or even Optane territory. RAMdisks are generally well past diminishing returns. They look great on synthetics, but the bottleneck instantly shifts elsewhere when doing most real-world usage.

I would recommend looking at performance results and prices before drawing that conclusion :).

The keywords are "to me". As an average user and gamer, I wouldn't see the minor differences between the SK Gold and this drive in real life daily use, while the price difference is considerable: $103 for the 1TB SK Gold at the time of writing, and can be had for $90 in some price reductions I've seen from time to time. The Platinum is currently at it's starting price of $150 for the 1TB version; in this case, the P44 would be an obvious winner.

I suspect this thing's reign in the TPU performance charts is short-lived, it's about to get utterly murdered by the 990 Pro, assuming W1zzard has one for testing in the near future.

In this regard, SSDs won't improve much, certainly not in the foreseeable future, as the development model will remain "more of the same". Developers of OSes, applications and games need to take the effort and expand the use of queues ... by a lot.

Interesting how the 1TB model edged out the 2TB model in quite a few benchmarks...................

@W1zzard which HDD did you use for reference? thanks

So reading all the data it seems there are multiple SSD's that are better value and equally fast. For example, the WD SD770 black. 99% of the performance and much cheaper to name one. No one would tell if you chose anyone of about 2 dozen different SSD's IMO. Finally, no 4TB option is starting to p!ss me off.

I think it would be smart for a storage company to time their release with the coming of the first DirectStorage game, and use that as a selling point... Oh wait, it's not planned for this year, and even later there doesn't seem to be great enthusiasm by developers.

Exactly .. everybody was thinking "DirectStorage = sales$$$", but then it turns out to be vaporware, and v1.1 is already announced, but of course with nothing to show.
Just a few weeks ago Phison did a round of press "reviews" with their friends, testing some synthetic traffic patterns that they think DirectStorage will need, without any evidence (there are no games using it)

which HDD did you use for reference? thanks
It's listed on the Test System page: WD Black 1 TB 7200 RPM 3.5" SATA

Would it be possible in future reviews to see the power consumption numbers? Thank you for the hard work and great review always.

Yeah, I have a Quarch now, but need to figure out what I want to test, and how, etc

Thanks.

I reviewed it twice and missed that. Time for glasses or something I think.

Edit another odd thing are the write endurance
500 TBW for 512GB,
750TBW - 1TB and
1250TBW for 2TB

one would have assumed
500
1000
2000
I guess that would be more for MLC vs this TLC nand??

The Platinum is currently at it's starting price of $150 for the 1TB version; in this case, the P44 would be an obvious winner.

One of the things gets lost in all the SSD hubub about speeds, benchmarks, and endurance as that all the top stuff is not designed for consumers. Including (perhaps especially) gamers who have no business buying it. Of course they'll take your money. But they are built for professional usage situations. For consumers there are some contractors or people who require homesystems as well to do work where these do make sense. There are applications and usage cases where there is a noticeable difference in the speeds here. At the enterpise level where these drives do wear with multiple VMs erased, created, scratch files, imaging constantly, endurance does matter.

But this is simply not for normal users. These drives make as much sense for most people as getting 10gbe and wiring it into the 10gbe port on your switch when of course nothing on your network has one and doesn't do squat when your switch connects to the router at 1gbe and you're router connects to your ISP at not 10gbe either. Unless you are professional and have say a NAS with 10gbe and are constantly writing to the thing.

This is shades of back in the day when we all had shitty DSL and people would load up RAID cards and SAS drives and people would get frustrated that this did nothing for online Deathmatch. Well of course, gaming isn't a professional application at all. And this may load a game faster, but it has no impact on playing the game, getting into a match, or anything your doing day to day. You just nuked ant, congrats!
Kind of sad seeing those tests where everything is relatively close e.g. minor real world improvement between this and a Crucial 2.5” 500 from yesteryear. Is this due to the limited real estate of the M.2 form factor for engineers, or do we have to wait another decade or two for a fundamentally different memory technology?
As stated this is mostly usage case. Simply put gaming and what most people do isn't a real storage system thrasher, it's not enterprise of professional work it's largely all a laughable joke of childs play.

In the enterprise though U.2 is still a thing, and yes the form factors are difference and vastly so. But that would not change anything if all you are doing is loading an OS, using the internet, messing with MS office, and playing games. None of those are going to stress a storage system. All of those cases are "buy the cheapest one that works and that's more than good enough" cases.

I heard you have a thing called "duck test" in English-speaking lands. Might be helpful here.
