I looked up the serial number for the SSD from the new 512GB OLED model, but couldn’t find anything about it specifically. I bought the 64GB model of the LCD Deck previously, so I don’t know if the SSD in the new 512GB OLED model is different or not. Just curious if anyone knows what the drive’s specs are.
Here’s an article regarding the SSD used: https://kotaku.com/steam-deck-valve-specs-components-ssd-downgrade-pc-1849126677
It seems that there’s no additional information about these drives but you can tell if yours run PCIe 3.0 x4 vs. PCIe 3.0 x2 based on the P/N.
The 512 GB OLED Deck that YouTuber Taki Udon seems to have the PCIe 3.0 x4 SSD but YMMV…
