A blazingly fast SSD is excruciatingly slow RAM.
- PartiallyTyped 6y agoI am trying to figure out where I said anything on the contrary.
- matkoniecz 6y agoYou mentioned "they come with blazingly fast SSDs" as part of what is "allowing devices to get away with less available memory"
- PartiallyTyped 6y agoI did indeed, I never said that SSDs are a replacement for RAM, I just said that having access to 2.5GiB/s RW operations allows you to offload many things into the SSD, yes, thrashing is an issue, but it is much more insignificant at those speeds than disks. I am not defending apple in any way whatsoever, I even mentioned in the first sentence of the comment. I stated that they are able to do that because they compensate with compression and SSDs, applications in the background can be thrown in the swap and the user will rarely notice.
- kamranjon 6y agoI think they are saying that you will start swapping to disk with that little ram.
- znpy 6y agoI don't even bother reasoning with apple fans anymore. It's a losing game.
- PartiallyTyped 6y agoIt's not even an argument, their comment is a fact that does not change nor contribute anything.
- kaba0 6y agoIn-memory memory compression is the most meaningful part of what parent comment said. And it helps tremendously on other systems as well, for example zram is quite underhyped on linux.
- rogers18445 6y agozram is a game changer. I believed I needed to upgrade 16gb to 32gb, with zram and a decent cpu no I don't. 97% full memory + 20GB zram swap and no noticeable problems.
- r00fus 6y agoThe M1 SoC interconnects are what makes their SSD seem like swapping to disk doesn't even feel slow.
