Anecdata, but SSDs will last longer than you want to use them in terms of write endurance.
My NAS OS SSDs are 500gb hynix drives from about 8 years ago, and they’re pushing 150 TBW.
150TB is a LOT of write cycles on a small drive, and they’re still reporting 94% endurance remaining.
The controller will die or I’ll upgrade well before that breaks at the rate it’s going.
Also keep in mind that you can read flash all you want and that doesn’t wear anything (unlike a HDD, amusingly), so for most consumer use cases, they’ll load the drive up with their data, and then only slowly modify or add to it, but have lots and lots of read access.
It’s not that they don’t work.
Basically what you’ll see is kinda like a cache miss, except the stall time to go ‘oops, don’t have that’ and go out and get the required bits is very slow, and so you can see 8gb cards getting 20fps, and 16gb ones getting 40 or 60, simply because the path to get the missing textures is fucking slow.
And worse, you’ll get big framerate dips and the game will feel like absolute shit because you keep running into hitches loading textures.
It’s made worse in games where you can’t reasonably predict what texture you’ll get next (ex. Fortnite and other such online things that are you know, played by a lot of people) but even games where you might be able to reasonably guess, you’re still going to run into the simple fact that the textures from a modern game are simply higher quality and thus bigger than the ones you might have had 5 years ago and thus 8gb in 2019 and 8gb in 2025 is not an equivalent thing.
It’s crippling the performance of the GPU that may be able to perform substantially better, and for a relatively low BOM cost decrease. They’re trash, and should all end up in the trash.
