macOS 似乎并没有解决 M1 机器 SSD 过度写入的问题

[dingwen07]

23 小时，写入从 7.14TB 到 9.03TB，机器是 16GB 内存、512GB 外存。电脑是在 8 月 16 日到的，我基本上不在上面做大型任务（我也没什么大型任务），半个月就 9TB 写入，我认为还是有挺大问题的。

11 月底 8g m1 mbp, 8g 是真不够用的, Xcode+钉钉完全不够

最近用电脑有点多，大概写入和读取都是 1TB/10 天这个样子

@chendy #39 我觉得可信，因为它是直接读数据的，而且那个 2TB 的写入和系统自带任务管理器里的磁盘写入数据一致

[parametrix]

我真是怀疑这个 feature/bug 贯穿苹果全系，包括电脑手机还有平板（说不定手表也是），要不然内存为什么给的那么抠？怕不是哪个小天才发明了一种神奇的内存调度机制，能够有效的把非高频读写的内存数据分配到 swap 上，配合够快的 ssd 做到让用户对内存不足感知不强。

@EvilDevilJin #27 请问这是什么 shell 的界面？

[zacklin99]

@dingwen07 微信有 m1 版了。不过应该不是微信的问题。应该还是内存压力的问题。

@yyh325 4 个半月才通电 65 个小时？

[jfdnet]

@parametrix 国产安卓机今年也开始推广这个功能了。swap （内存融合）。不得不佩服这取名字的人。
