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？

    这是一个创建于 1148 天前的主题，其中的信息可能已经有所发展或是发生改变。

    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

    平均一个小时写 187.7GB ，虽然意料内，但看着还是有点夸张

    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

    @Tink 就工作用的电脑。按照自己习惯使用。
    多个 idea 项目+docker （数据库）+chrome 几十个 tab+几乎不关机

    一台电脑也就用个几年，用的爽就行了，担心这个那个，不如供起来。

    @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。

    用 HTOP? 看看究竟是那个程序读写这么多

    可以考虑用 Ramdisk 缓解一下

    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？
