虽然所有的Steam Deck 256GB和512GB型号最初都配备了PCI express 3.0 x4 SSD，但现在部分产品更改为PCI express 3.0 x2 SSD。

Wayback Machine证实，Valve在5月底悄悄调整了Steam Deck官网上列出的技术规格，以说明这些变化，该消息由Hardware Luxx首先曝光(PC Gamer)。

尽管Valve声称他们的测试并未发现使用x2 SSD会对游戏性能产生任何影响，但他们并未提及对加载时间或响应速度的影响。

目前Steam Deck技术规格表的存储部分为：

64 GB eMMC (PCIe Gen 2 x1)

256 GB NVMe SSD (PCIe Gen 3 x4 or PCIe Gen 3 x2*)

512 GB high-speed NVMe SSD (PCIe Gen 3 x4 or PCIe Gen 3 x2*)

All models use socketed 2230 m.2 modules (not intended for end-user replacement)

All models include high-speed microSD card slot

*Some 256GB and 512GB models ship with a PCIe Gen 3 x2 SSD. In our testing, we did not see any impact to gaming performance between x2 and x4.

由于材料短缺，Steam Deck推迟了两个月于今年2月推出，目前Valve正在努力完成积压的订单。官方在周一表示，计划从本周开始大幅提高Steam Deck的出货量。
