@gowk 而且 100 多条回答里面，就只有他的回答比较有意义。是不是很讽刺

@SuperXRay

这一代的确写入量大

@SuperXRay 有意义那厂家还写 150TBW 干嘛

不知道这代用的到底是怎样的闪存
kioxia 的 tc10 240G 的寿命非常短，rc10 也好不了多少，不信的话可以自己去查一下。tc10 240G 是 64 层和 96 层混着用的，都是铠侠的原厂闪存。不清楚苹果能要到多好的闪存，但是感觉 kioxia 的闪存寿命不会很长
以前买的三星 850evo 120G，是 75t tbw，250G 也是。现在的闪存的寿命是更长还是更短还不好说，850evo 是 40nm 的 3d tlc
没有查到苹果用的闪存的信息，而且表面似乎被打磨了。不过有意思的地方是有 2 块闪存，毕竟没有找到什么关于闪存的有价值的信息，感觉可能是有一定的冗余吧，不然找这个趋势，如果是一般的 kioxia 96 层 TLC 还真的撑不过 2 年
