Ask HN: Has the Apple Silicon excessive disk read/write issue been fixed?

Launch day purchased M1 MacBook Pro with 4TB SSD.

I have custom pmset setup to NOT dump to disk (mostly) with two aliases:

    pmset-fast: sudo pmset -ab hibernatemode 0 sleep 0
    pmset-secure: sudo pmset -ab hibernatemode 25 sleep 0 displaysleep 1

First one is memory only, if the battery dies, the battery dies and the OS goes away.

The second one is hard drive only, closing the lid writes to disk only and puts the laptop into deep sleep.

I know I'm weird for having this but since I run the first one (fast) 99% of the time I can basically say I almost never write hibernation files to disk.

Thank you, this is useful. I think I'm going to try the memory only option. Your Read/Writes seem lower than others (still pretty high, but much better than other Apple Silicon)

Is there a noticeable difference in battery life usage with option 1?
