移动SSD要发挥高速需接口和线材双匹配：USB3.2 Gen2达10Gbps(约1000MB/s)，Gen2x2达20Gbps；若电脑只有USB3.0(5Gbps)接口，再快的SSD也被限速到约500MB/s

Unverified移动SSD接口标称USB3.2 Gen2(10Gbps)理论上限约1000MB/s，Gen2x2(20Gbps)约2000MB/s；若电脑或线材不支持对应协议则速度会被限制在较低档，需线材、主机、盘三者协议一致才能跑满标称速度92% similarUnverified传输速率标注需认准具体协议：USB 3.2 Gen1=5Gbps、Gen2=10Gbps、Gen2x2=20Gbps，仅标'USB 3.0'实为5Gbps；接NVMe SSD要满速需选10Gbps及以上82% similarUnverified接口协议决定实际速度：USB 3.2 Gen1(=USB3.0)理论5Gbps约500MB/s，Gen2达10Gbps约1000MB/s，Gen2x2达20Gbps；买了PCIe SSD却只配Gen1接口是性能浪费，选购时接口协议要匹配盘体速度81% similarUnverified选购PSSD要认准接口协议而非仅看接口形状：USB 3.2 Gen2（10Gbps）实际速度约1000MB/s，USB 3.2 Gen2x2（20Gbps）约2000MB/s，仅标'Type-C'不等于高速，很多Type-C口只是USB 3.0（5Gbps）速度约500MB/s81% similar
