I understand that the M2 chip has a unified memory architecture, where the RAM and SSD are integrated on the same chip and optimized.
However, memory swapping is still basically just moving data between RAM and SSD, so generally the faster the drive, the faster the swap.
So far, no matter how many tabs/apps I open, I still can’t utilize more than the 16GB RAM I have to trigger a memory swap, so I can’t quite test that theory.
There are a few variables though. Obviously a slower ssd or enclosure interface will produce a slower result. For the case you mentioned, it seems pretty extreme that the memory swap was almost unusable.
Which external ssd was the YouTuber using? Was it a Gen 4 NVMe external SSD connected via Thunderbolt 4?
Maybe you could share that YouTube video? Thanks.
Since you have 16Gb ram, I think you will hardly get into memory swap so probably no need to worry about it. Lazy to find the video
I am using base M2 mini, using internal SSD for OS and apps, and a TB3 enclosure with 1TB SSD for extra storage. Works well for me, the external SSB can get about 2700MB/S read, 2400MB/S write but it is overkill for me actually.....
