既然你问了，那就不要想了，退掉吧，只要有读写那就是不正常的

1T 的硬盘写入寿命在 1500T 到 3000T ，你这数据一天写入也就 50G ，1500*1000/50/365=82 年
你这写入量和我日均差不多，我的用了 11 个月了，写入量 20T

按照这个推算，双固态芯片的 256G 可以写到 1638T 。按目前的使用量，推算可以用 20 年。

慌什么。固态就使劲写就完事了。写到报废早就换电脑了。用了很多年的台式机表示都没有扛过 10 年的主板，但是扛过 30 年的 HDD 倒是神一样的存在！

说明用不着 32 ，除非 swap 常年 10GB 并且还在不停交换的人，都用不着加这钱。。
Pro 因为交换快，几乎所有使用场景下 16 和 32 的性能差距只有 5%以内，可以说是误差

xtinput

2022-10-20 10:21:23 +08:00

@234ygg 16G 的在内存用到 14 左右就会用到交换内存了，硬盘速度和内存速度性能差距 5%？
内存的带宽最低 100GB ，硬盘的不到 40GB 带宽吧，再加上硬盘读写的延迟
我 32G 长期使用 24G 以上，前两天有几台虚拟机忘记关，32G 运行内存的都把 swap 干到了 10G ，直接卡成狗。强制关机才恢复

xtinput

2022-10-20 10:25:02 +08:00

@234ygg 内存压力黄了就有感觉了，与交换内存大小不是线性关系

@234ygg 对了，还有一点忘记说了，苹果的 M 芯片是统一内存，之前 intel 的集成显卡有自己的独立内存，也就是说还要把 GPU 占用的内存给保留出来，M 芯片硬盘大量读写我感觉就是这个问题，物理内存被 CPU 占用了，GPU 渲染使用的是交换内存，然后因现在硬盘读写速度很快所以卡顿感不明显

@xtinput
上面说了重点就是，常年占用 swap 并且还在不停交换的人才需要更大内存。虚拟机开着不关明显属于此范畴...

不过还是建议不用就自动 sleeping ，收不回来的内存只能 swap ，内存控制的压力大了效率就下去了...
16 和 32 确实在几乎所有场景没什么速度差距，Google YouTube 一下就能找到各种生产力工具的测试对比
