PCs in general can't take advantage of fast NVMe speeds very well when it comes to game performance. There's barely any difference in load times when comparing a slow NVMe to a fast one.

edit: there's barely any difference when comparing a SATA SSD to a PCIe Gen 4 NVMe in most circumstances. This may change in the future as game developers actually add multithreaded decompression algorithms to their game engines in order to take advantage of the new console SSDs, but it seems like that will be a somewhat slow change in the industry.

Smaller SSDs like the 256 and 512GB drives Valve is using in the steam deck do have lower IOPS scores, but not enough to actually matter when it comes to game loading.

Remember when everyone said I was a crazy luddite for claiming that running stuff off the sd card would work perfectly fine. That was funny.

Has anyone ever had an SD card that lasted more than 1 year? I have to replace my dashcam SD card every year or so because the files always gets corrupted. I'm not using no name cards too, I have tried sandisk and samsung and the results are the same.

Your dashcam is constantly overwriting the entire card every day or two, it's like the worst-case scenario for flash memory short of throwing it in a fire or something. I've got some microSD cards i just keep music and backup files on that are better part of a decade old and still fine

Also the extreme heat of being in a car during the day in the summer time. I know my dash cam specifically asks to use their own cards just because they last longer. But the manual still says the camera shouldn't be in a car when it is hot out. Not that anyone listens to that part (hell, I'm just as guilty), but it is there. I've got really old cards I still use. From years and years ago and they still work fine. In fact, I have worse luck when it comes to usb flash drives. With one that I wrote some back ups on to and then when attempting to view it later had the drive be corrupted.

Information from a developer presentation Valve gave recently: https://videocardz.com/newz/valve-details-steam-deck-hardware-the-amd-zen2-rdna2-soc-is-codenamed-aerith

Relevant to a topic that has come up several times:



Valve is claiming that loading games off of an SD card will take only 18% longer than off the NVMe. Again, raw read/write throughput is one of the less important specs when it comes to game load performance. Random read/write performance as well as CPU performance are much more important, and SD cards have better random read/write performance than HDDs. I doubt Valve is trying to mislead anyone with these slides, so they probably accurately reflect the testing they've done internally, though independent analysis once the thing is out will be necessary to explore all the ins and outs of the steam deck's storage systems.

I find it weird that load times are still a reference as many games and many engines are based around streaming assets. The initial load time has become comparibly irrelevant in todays games worlds... but no one wants their experience tainted by micro stutters or slow texture/shader loading when moving around or fast traveling or whatever. Imo thats why fast storage is relevant among other things.

"Fast" for streaming assets is primarily random access time, and less throughput. That's why flash based storage is so great, even when it has lower throughput.

If the game loads once and then streams everything afterwards, an extra 10-20 seconds on the load isn't a big deal. If the game has lots of loading screens, they are most likely going to be short anyway.

In ten years when every game assumes it'll have access to Direct Storage, maybe SD cards won't be a good choice. Today, when games are still functionally accessing data the same way they did with hard drives, when the generation of consoles just gone used literal platter drives, when no game has an actual requirement for an SSD at all, an SD card will work just fine.

the only games that do anything like that are big open world games thatll strugugle on the cpu anyway, and the load difference on those games isnt 10-20 seconds, its minutes. ac valhalla is a full 2 minutes longer to load off a slow drive than a pcie4 ssd, and you still have to do more loading for fast travel wherhe you can be sitting for a full 60 seconds to load off a platter. have t o say the insane ssd isnt that much faster revisionism is epic

Ac valhalla, which probably won't run well on the deck anyway, is 28 seconds longer to load on a mechanical hard drive. (40 seconds vs 12 seconds). The SD card will likely perform better (than the mechanical drive, obviously).

work out the average size of a switch game and the level of compression on its assets for the games specifically made for that hardware then compare and contrast to the full fat pc games you will have to install. lucky its cpu is so bad u dont have to really worry about the big open world games i guess lol

I'm willing to bet that the vast majority of games that run at playable framerates on the deck will also have acceptable loading times. And for those that don't, you can just move them to the internal ssd.

The point that stux is very poorly making is that the CPU is going to be a large bottleneck in load times. Moving games from the micro SD to the SSD may not result in a large decrease in load times because the CPU may not be able to load the assets quickly enough to matter.

He's pretty heavily underestimating the capabilities of the CPU though. It's not a great CPU by any means but he's being hyperbolic.

I don't understand what you people are arguing about.

Of course the Deck can't load or stream games as quickly as the new and significantly more powerful generation of consoles. Or in some cases even the Switch, which gets/requires very optimized ports.

It's a bit surprising that Steam chose NVME considering its higher power consumption but I suppose they wanted to look to the future.

Now I wonder if the Deck might throttle the NVME drive to a noticeable degree to avoid thermal issues, especially if the CPU is a bottleneck anyway — which perhaps brings average power consumption to a point lower than or equal to saturated SATA?

I guess I'm saying maybe Steam chose NVME mainly to reduce power consumption through throttling, and 1) the increased speeds over SATA will be even less noticeable than what you'd expect, and 2) the Deck will never utilize NVME fully even as more PC games are designed with it in mind.

Edit: lol nevermind, I misread the entire conversation above.
