I use it as a Soundacrhiv SSD - with 70,00 files and about 1.8 TB - works best on the Mac Studio. But every now and then I get the message that I haven't properly logged on the drive, but I haven't unplugged it, it's always plugged in.... But it still works perfectly. And yes, formatting the Mac beforehand certainly makes sense - I formatted it APFS. Greetings. A.
