The base model m2 has a slower ssd than the m1. Multiple sources including the verge max tech and others have confirmed it. Apple is charging more for the base m2 air, yet they outfitted it with a slower ssd than its predecessor. So what are you getting by paying more for the base m2 model vs the base m1?Is it? In what regard? Do we have any videos of the thing actually being used for tasks or is it all isolated benchmarks?
To use an analogy, if the “engine” of this car is technically slower, but a new version of the transmission results in it still going 0-60 faster…is that a problem?
1400 MB/sec of the base model is a similar in speed to the 2018 intel MacBooks. (I note that you can get 1 TB pcie4.0 drives from western digital and Samsung and Kingston with 6000 MB/sec for approx $110.00. This is a far better value than the +$200 extra apple charges for only 256 GB of additional storage. Also, pcie5.0 nvme storage with 13,000MB/sec is coming later this year. Of course apple doesn’t let you add any internal nvme storage, even though macOS will boot just fine from fast pcie4.0 nvme storage).
With SSDs, you must consider another metric in addition to their sequential speed rating: which is their performance after they run out of cache. Some drives like the WD Black SN850 or Samsung 980 pro operate well and maintain great performance after cache runs down, but other drives, including the one in the base m2 air, slow down dramatically.
Given that the current versions of macOS require more memory than earlier versions like Sierra, 8 GB RAM on the base model is barely enough. The machine will need to use swap as you load up more programs.
So the speed of the disk storage becomes relevant as the OS needs swap memory. Therefore, if the ssd is slower than the predecessor, and it has slow performance once the SLC cache runs out, that could negatively affect the overall responsiveness of the system and possibly cause it to slow down as more programs that consume RAM are loaded up.
M2 in isolation might be great, but it’s the performance of the overall system is what’s important. Therefore, what’s paramount is how all the components work together. Balance is key. What good is a fast cpu if the slower ssd causes responsiveness to decrease? There needs to be balance between, M2, disk speed, the cooling system and so on. M2 may be great in isolation, but if overall system responsiveness (of the base m2 vs the base m1) diminishes as more swap is used, then there’s a problem. A design flaw in my opinion. Apple makes better machines. I have the 14” pro and I love it.
It seems as if for m2, 16 GB RAM and 512 GB storage is the SweetSpot. But that’s an extra $400 over the base model. So is it worth spending all that money on an air when there’s potentially better options in that price range?
Finally, the question purchasers should ask themselves is: is 8 GB ram going to be enough years from now? Because future versions of macOS may be even more RAM intensive than Monterey. Monterey is far more ram intensive than Sierra and el capitan. Thus, the speed of the disk (and swap memory) could become even more important in future iterations of macOS as compared to Monterey. Unfortunately, if you need more RAM in the future, you can’t add it… you have to replace the machine. So, no matter how you feel about m2, if you buy it my message is please be wise in your purchase decision and think about the amount of RAM and disk speed performance you’re going to need not only in 2022, but also for the years to come.
