Anyone who bought one of Valve’s Steam Decks at launch got a very particular model of solid state drive installed in their device. Anyone buying one more recently has received a different drive, one that’s potentially slower.
As Hardwareluxx report (via PC Gamer), all Steam Decks that originally shipped with either a 256 or 512GB SSD would have had them connected via four “lanes”. Now some units are shipping with drives that connect via just two “lanes”, a change that could in theory result in slower performance since you’re essentially halving the drive’s bandwidth.
This downgrade wasn’t publicly announced via a press release or statement, and Steam Decks shipping with these newer drives haven’t been differentiated by a new model number. Indeed the only public mention of the change at all came from Valve quietly editing the handheld’s specs page back at the end of May.
As a result, the only way you can find out whether you have the original, theoretically slightly faster SSD installed in your Steam Deck or not is to check its specs in the system’s menu. Under “Hard Disk Drive”, as PC Gamer advise, you need to look for:
In the right panel it’ll have a code. Our 512GB review model has a Phison ESMP512GKB4C3-E13TS drive. That seems to be a custom 2230 SSD using Phison’s Gen3 x4 E13 controller. So, you want to check whether your code ends with -E13T, too, or something else entirely. If it includes a code like -E08 (Phison’s Gen3 x2 controller) then your Deck is one of those with a drive running on a Gen3 x2 interface.
I’ve been cautious with my language about performance above because we haven’t seen any tests that prove there’s a clear difference in stuff like load times or fps between drives, at least on games currently available and fully supported on the platform. Which is understandable given the fact the news has only just been reported, and that with units still hard to get hold of few if any people will have two Steam Decks they can directly compare with.
But those tests will come, and it’ll be interesting to see what they find, because if I bought a Steam Deck now—and it’s getting easier—only to find that I had a different unit to other people, despite them sharing the same model number and with the change having been so quietly made, I would not be exactly happy!
