目前最好的PCIE4 VNMe SSD 具有2TB 容量可具备1200TBW 耐久性
M1 用户超过TBW 极限数值后，虽然依旧可以让SSD 继续运行，是否会造成SSD 读写出现问题或是能够持续使用多长时间？这些问题都是未知数。
如何查SSD 寿命？
如果是M1 Mac 用户担心SSD 损耗严重，也能够打开终端机输入底下指令来查询
brew install smartmontools
利用diskutil list 查硬盘符号
diskutil list
查到硬盘后（例如刚查到是disk0s2），就直接透过底下指令查询SSD 硬盘健康度，就可看见Percentage Used 数值就是耗损趴数。
smartctl -a disk0s2
