Unverified读写速度约2800MB/s属于Thunderbolt 3移动SSD的主流水平，但相比同容量普通USB 3.2 PSSD价格高出数倍，预算有限且对速度要求不极端的用户性价比不高85% similarUnverified机械硬盘阵列即便RAID0/5实际持续读写通常也在几百MB/s量级，此时USB3.2 Gen2(10Gbps≈1000MB/s)已足够，只有全SSD阵列才需要Thunderbolt发挥价值79% similarUnverified4K/8K多机位剪辑建议使用Thunderbolt 3/4外置阵列或内置NVMe，实测持续读取需≥1000MB/s才能保证多流预览不卡顿75% similarUnverifiedSSD要认PCIe 4.0(读速≥5000MB/s)而非PCIe 3.0，但部分低价机型宣传4.0接口却搭载QLC颗粒，持续写入掉速严重，视频剪辑/大文件操作应查颗粒类型75% similar
