I notice that every time I open one of my DNG images in Develop module, with one or two very light edits, Lightroom does over 1 gigabyte of writes to the disk. There are other serious hammerings of the disk with other operations in Lightroom classic as well. Opening a reasonable length Lightroom session where I edit 50 or 60 pictures can result in 300 Gigabytes of writes. I am using a 16G M1 as well so there is plenty of memory. I am running very latest (as of Feb 20 2021) Lightroom Classic and Big Sur 11.2.1 - so the very latest. I notice that Lightroom, more than any other SW I have, just loves guzzling memory. Why? I think there is a serious memory leak in this software.
Why does Lightroom thrash the disk so much? No other app that I have, and I have many graphical apps, thrashes the disk anything like what Lightroom does. I did testing with LR Cloud and it is the same.
An SSD cannot sustain a thrashing like this for sustained periods of several years. Lightroom is actually effecting the longevity of the computer. I have read some similar threads about this, for example, here:
Same here. Im just waiting fore Capture One to arrive native for M1 ( or maybe finally Seriff DAM release). My iPad runs lightroom better than M1 mac rn. Its a major dissapointment for me - hundreds of gigabytes written to ssd from just looking at the photos. Adobe fix your stuff or fire your coding departament - your code can destroy computers.
