![]() ![]() I remember seeing this a long time ago when I was reading about SSD technology, and this YouTuber I watch mentioned the same rating for the M1 ones. Still, my 2013 Air used 1GB of RAM with no swap when idling, and it's a much older machine that was definitely not made with Big Sur in mind. I'll see how it goes, but this is obviously huge progress from the 1GB swap used when idling with no apps open. Swap usage was obviously still constantly changing, but I rebooted after I made those changes and guess what? Even with Illustrator AND Safari open I get 0 bytes of swap usage. I decided I'll delete all Safari cache and stop Spotlight from indexing Documents (the folder in which I'm constantly editing my Pages files and where I store the Adobe files I work with). Possibly some system processes aren't terminating correctly, which in turn abuses the process kernel_task (the main culprit), which is technically responsible for swap. ![]() This is still a legitimate concern and it seems that something hogs the memory, as the system runs fine when it isn't using swap. M1 owners (especially the ones with 8GB RAM) what's your swap usage and your Data units written in DriveDx? ![]() I understand the 8GB model is not enough for a lot of use cases, but even the 16GB models swap a lot from what I've seen. "It just works" but for how long? This is obviously exhausting the SSD with VERY light usage for a Pro machine. And in general they want to make everything seem like magic so they naturally avoid speaking about anything that sounds techy. When (not if) the drives on these start failing they'd certainly be out of warranty so it would practically be a non-issue for them. Sadly I don't think we would ever be able to get an opinion from Apple themselves though. Especially since wearing out the SSD means having to buy a new computer now. I know some people on here will say this is bs and whatnot else, I know Apple has thought it out, but it is a legitimate concern. I know SSD endurance is something we're told not to worry about often because nowadays SSDs last for much longer than they did before, but writing a TB every 20 hours or so is not at all good for an SSD and would technically burn through one rated for 300TBW in less than a year. That's concerning! And my usage doesn't differ from pretty much every pseudo-pro user that got the base M1 Pro - some Adobe apps here and there, but mostly just Pages and Keynote. SSDs have a limited lifespan, and the SK Hynix ones Apple uses for these Macs have been rated for about 300TB written. SSD health for that Air is rated at 83% by DriveDx, which is fine.Īs you can see, the SSD has been up for about 13 hours and yet about a TB of data has already been written to it, mostly by swap. My 2013 Air has been (ab)used daily for 7 years and the SSD data units written account for about 30TB, which is not a lot at all. Now, the computer is performing incredibly well despite swap, and it's not swap happening that's concerning (swap has been a thing for ages) but the fact that it swaps way more than my previous MacBook. Opening Safari with two or three light tabs brings swap in the GBs, and Adobe Illustrator usually brings swap in the 4-5GB range. Having just booted and without opening any apps I get around 6GB of used RAM and about 500MB of swap. I got the 8GB RAM, 256GB SSD one because anything other than the base model would've meant an additional 2.5 months of waiting (I live in the balkans.) and I'm noticing incredibly high swap usage. But, there's something that no one is discussing, or at least I couldn't find any info on the internet about this regarding the M1 Macs (maybe mine is faulty?) I'm very happy with it and it's a huge jump from the Air I had. Alright so I got the M1 MacBook Pro (upgraded from a 2013 MacBook Air) and the performance is incredible. ![]()
