alt Hacker News> Apple Silicon Macs are much more efficient with memory than even the Intel Macs
So either it has magic fairy dust, or more likely it swaps a lot, but thankfully today's flash is faster than yesterday's hard disk; though this intense usage will shorten its life. By the way I wonder if Apple will use cheap QLC for this.
macOS actually does the opposite; to avoid wearing down the drive it will hold 7-10gb of your most commonly used files in memory and release them when the memory gets allocated for something else. In theory you could get away with editing gigabytes of files and using dozens of apps without ever wearing down your drive at all.
