Valve's first game console Steam Deck has received enthusiastic attention from everyone once it was launched, including many game enthusiasts. After all, V's handheld console is still quite competitive. However, some players have now discovered that V seems to be taking action on the Steam Deck, such as making changes to SSD, mainly because the bandwidth of the SSD has been reduced.
In the past, Steam Deck had three versions, of which 64GB used eMMC storage based on PCIe 2.0 x1 bandwidth, while 256GB and 512GB used NVMe SSD with PCIe 3.0 x4 channels, which means that it can theoretically provide 4GB/s, generally It's easy to exceed 3GB/s. However, some netizens have now discovered that even the 256GB and 512GB versions have relatively large differences in bandwidth. For example, in addition to PCIe 3.0x4, an additional PCIe 3.0x2 channel is added, which means that the bandwidth is cut in half, with a maximum of only 2GB/s.
Although this is the case, Valve stated that this has no impact on game performance. Players will not feel game lag even if they use PCIe 3.0x2 SSD. However, Valve did not indicate which Steam Deck uses PCIe 3.0 x2 SSD, which seems like a blind box. As for third-party SSDs, Valve does not recommend replacement because there is no special optimization.
