This is going to be all about how fast the SSDs are in all three of these systems.

这个测试是要比较这三个系统的固态盘到底有多快。

I've embraced USB-C with cables, with SSDs, but I always find myself needing an SD card slot.

我用过 USB-C 连接过充电线啦，SSD 啦，但总是觉得需要一个 SD 卡槽。

Today, costs have fallen so far, that hard disk drives are being replaced with non-volatile, Solid State Drives, or SSDs, as the cool kids say.

如今，成本已大幅下降，硬盘驱动器正在被非易失性固态驱动器或 SSD 取代，正如酷孩子所说。

Firstly, the original 5400 RPM hard drives, those are about 100 megabytes per second read and write whereas, with the SSDs, those are about four to five times performance, just about 500 megabytes per second read and write.

首先，原来的5400 RPM 硬盘每秒的读写速度约为100mb，而换了 SSD 之后，翻了四到五倍，每秒的读写速度约为500mb。
