It's the same amounts of hits, writes/reads are the same. I don't think you'll have to worry about the problem with the lower end machines having only 1 ssd chip and being slower, I've never seen anyone complain about the Studio for that kind of problem. That said, 512G is pretty small, I went with 1TB just because I need that much.I'm still trying to get a handle on the internal SSD for the Mac Studio. with 512gb, do you get more read/write hits vs with a 1TB, therefore more wear and tear?
External has never been just as fast as internal for me. External's pretty slow due to it being over a Thunderbolt or USB connection.What if I stay with 512GB, and go external with 1 or 2TB SSD. Looking at specs and YouTubers with that configuration, speed is just as good. specifically:
SSD and SSD enclosure
So, apple charges $200 upgrade for 1TB, and external about the same. Plus already have the enclosure, so interchange additional SSDs if needed.
What the speed of the external SSD, could offload things like Parallels, etc.
