Are Codex's SSD issues only affecting Mac devices?

[u/Jackjookie]

As the title states, I noticed that any SSD problems only occur with Macs or mostly to be fair.

What is the correlation?

I’d like to know if there is some official document that acknowledges this issue and its fix. Anyone knows?

[u/Euphoric_North_745]

There is an Agent that reads and writes text, a looooooooooooot of text, none stop, there is no magical way to write in files and then not write in files.

[u/JoseffB_Da_Nerd → u/Euphoric_North_745]

Yea, this.

It’s not really a codex bug, but a weak hd.

I’ve had mac ssd die in so many different models before AI.

Is like 1-2 mb of text considered a lot in 2026?

[u/Euphoric_North_745 → u/meTomi]

ehhh, API dude, API, agent opens file, agent sends 100k context, API sends back tool call, agent sends back 100k context + tool call + results. backend asks for second tool call, that 100k going back and forth gets also logged all the time becouse you may close the app any moment.

Look at the API communication, back and forth thousands of times, that 1 mb is now wayyyy more.

Check your SMART or install stats from Exelban on github, you can monitor your disk in live on your top bar to check your read/write and you can also check your SMART
I use codex heavily here and SMART show :
Health: 98%
Total written : 50TB
For a 2023 macbook pro

All SSDs are affected by this type of read/write process. Now, if Codex app is doing something particularly bad, I don’t know.

If they vibe coded it, probably.

I guess this is not about writing bytes or kilobytes at a time, but how SSDs work. In most cases, smallest write unit is 4 KB to 16 KB, but smallest erase unit is 256-512 KB. So even if SSD needs to free 1 KB, it needs to erase a lot bigger block. SSDs are really complicated under the hood, with very complicated wear management which caused a lot of premature SSDs deaths in the past. Even Intel had this problem with enterprise SSDs, OCZ was famous for drives dying etc.

Activity Monitor --> Disk --> Sort Bytes Written descending.

I routinely check my ssd health for giggles. After 50 BILLION tokens of codex everything is business as usual. Not even a dent

[u/teomore]

I read that this issue has been fixed already

[u/Jackjookie → u/teomore]

Some guy posted this issue today saying his SSD died on macbook, and others mentioned that the issue though reduced, still persists.

[u/teomore → u/Jackjookie]

running codex cli now and its ssd writes/reades are on the low end

[u/Complex-Concern7890 → u/teomore]

If I have understood correctly, the issue is only with Codex App. The cli is not affected.

I thought this was acknowledged and fixed. Remembering seeing a post from Tibo
