I know this is an old thread, but I would like to hear more from Dan on the Limits, and the "Sizable Chance" he speaks of. What EXACTLY have you seen as issues? Mainly the "Garbage collection" and "Protocols" that Apple runs that would not be supported?; Over-filling any SSD, under any circumstances [including phones] is a source of early failure [I like to leave mine around 1/3 empty].
SO hard to mix and match configurations to get the MOST, without breaking something, or "over-buying and not getting the benefit. I too have a 2019 imac-i9 and am currently booting from an external PCIe 3.0-NVMe-M2-4TB. IF I can't achieve anywhere near the speeds I am seeing going internal, I won't waste my time/$. It APPEARS that the 2019 iMAC does support the PCIE 3.0 NVMe-NOT M2? [IF I am reading correctly]; and not the 4.0. . .so I won't be able to get at least the same speed going Internal? Then perhaps size limitation? I cannot find as a "Matter of Fact" how Large can I go [8TB]?
