@syhily 感觉跟内存大小高度相关，我的 32GB 内存的 MacBook Pro 16，买了一年半多了，才写入 11.8TB 。M1 太可怕了。

@felixcode 正解单纯的闪存擦写次数未考虑写入放大 TBW 才是相对可靠的写入数据量寿命参考值

升级 11.3 据说基本就好多了，轻度使用前五天写了 300g，关了聚焦之后五天久写了 40g

@alian 内存够貌似也会，虽然我的不是 M 1 版本的，32g 内存，日常剩余 17g 可用，但是 swap 有 14g

楼主平日主要是做什么工作的啊？这么高的写入量吗？

你这个有点狠。。。
个人感觉 swap 高占用的话，硬盘的写入量会增长得很快
