只是形状。电脑端口、SSD 和线材会按共同支持的最低协议运行；另外标称值通常是顺序峰值，温度、缓存、文件数量和剩余容量都会让实际速度下降。","question":"USB-C 口为什么跑不到移动 SSD 的标称速度？"},{"answer":"不一定。20Gbps Gen 2x2 是 USB 3.2 的双通道模式，部分雷电/USB4 主机只向这类设备提供 10Gbps。下单前应查电脑的 USB

SSD 的 USB-C 只是接口形状。10Gbps、20Gbps Gen 2x2 和 USB4 是否能跑满，取决于电脑、硬盘和线材的共同能力；很多 Thunderbolt 4 Mac 对 USB 3.2 Gen 2x2 设备只按 10Gbps 工作。价格为 2026 年 10
