    这是一个创建于 242 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

    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
