Valve has downplayed the performance impact of using slower SSDs in new shipments of the Steam Deck.
The change was first spotted by German publication HardwareLuxx, which noticed the 256 GB and 512 GB versions of the Steam Deck now ship with either a two-lane or four-lane PCIe Gen 3 SSD. Previously, these versions all came with a faster four-lane SSD.
Asked by PC Gamer for comment, Valve’s product designer Lawrence Yang said Valve “determined that there is no impact to performance between the two models,” and there were only differences between the two drives in “extremely uncommon cases.”
