Macbook Air 2020 M1 consumes SSD life too fast. The SSD wrote twice as much data in two weeks as the Macbook Retina 2017 did in two years. I use VSCodium and Google Chrome for Web development. I haven't downloaded anything other than those programs. I haven't logged into iCloud. I have not connected any iPhones to this laptop. I haven't even downloaded old projects. I don't know exactly, I estimate my data on the SSD to be less than 1-5GB considering the programs I have installed in unpacked state. That said, smartctl shows that I have written 17Tb of data to the SSD and continue to write 1Tb daily. I honestly don't understand how this can be. I keep working on my old macbook with the same programs VSCodium and Google Chrome. The smartctl program says I'm writing about 20-30Mb per day. The number of writes to the SSD only goes up when I download files from the internet.
I have never tried XCode. Maybe there are special programs for Macbook M1 for web development.
If I replace VSCodium with XCode and Google Chrome with Safari, can my mac survive the rest of this year?
There is another tool
Let's see what the third column of the iostat output shows.
In the first screenshot I caught a not very good moment for comparison. When I ran the utility, Chrome Browser was loaded. The second screenshot corrects this awkwardness. The third screenshot is the old Macbook Retina 2017 running under a fairly high load.
i7core != m1core
To get this low write rate on the MacBook Air SSD, I had to turn Spotlight off. I also (not sure if that helps) disabled Time Machine. Yesterday's SSD write indications were 20-50 times higher.
On the old macbook, I didn't turn anything off. Not the browser, not VSCodium, not Spotlight, not Time Machine. Plus I have two VeraCrypt disk images connected.
