8g 256g m1 MacBook Air，才用了一个月，硬盘写入已经 22TB+了，你们的多少了？

zj9495 · 2021-02-23T07:41:00Z

1 月 21 日到手，去掉假期，平均一天写入 1TB，这 swap 也太狠了吧家里装了六七年的台式机的系统盘，写入量也才和这个一个月差不多，照这么下去，用不到一年固态硬盘就得先报废啊你们的使用情况如何？可以用下面的命令查看下 brew install smartmontools smartctl -a /dev/disk2

写入

smartctl

disk2

高端的 SSD （多使用 MLC 闪存）写入数据量没有低于 2.2PB 的，第二块三星 850 Pro 硬盘甚至写入了 9.1PB 的数据量，是官方 150TB 使用寿命的 60 多倍，每天写入 40GB 的话，这个 SSD 理论上能用 623 年。

电脑主板我记得是 2 年保修。这个焊在了主板上面，而且坏了没法启动，应该还是算主板坏
一个月 22TB，如果继续下去一年就是 200 多 TB，差不多就是同样容量的一般的 NVMe SSD 的 TBW 吧。应该活不到 2 年
如果只是单纯这样的话，保修期内又不要紧，坏了就换一台。主要是怕系统或者 SSD 主控觉得机器的 SSD 快写废了，给你疯狂限速，变得比 tf 卡还慢。正好 8G 的 mac 是特别吃 SSD 读写速度的，肯定会卡
而且不需要达到 TBW 就会开始降速，当然还和读写 NAND Flash 所需要的电压有关系，后期要加高电压才可以读写了，说不定 NAND Flash 的速度还会快一些，但是主控一般还是会选择降速吧

mbp m1 16G，写入 1.3T ，（ Power On Hours: 50 ），而且温度也只有 30 摄氏度
当初选择 16G 的原因之一就是担心频繁 swap 会影响硬盘寿命、增大能耗

三星 note2 时期的"字库门"就是因为 NAND 读写寿命耗尽吧?

不知道苹果有没有什么保障措施

@FS1P7dJz #80 然而就是很离谱。

我第一块 SSD，intel x25 g2，快 6 万小时通电（现在用作 MS Gen8 系统盘），70T 写入。
刚看了下我去年 12 月底买的 MBP16 低配（ 512+16 ），1136 小时通电，29.5T 写入。

为什么我用了快一年 Power On Hours 只有不到 300，但是 Power Cycles 却有 5000 多。这个 Power On Hours 显然不是实际使用时间啊。难道是因为硬盘大部分时间都在睡觉？
