so how does the 2025 upgrade knows that I am upgrading, if I wipe the older version?
And yeah, I am using SSD drives. I never said I wasn't, so that stuff is irrelevant. You seem to make a connection between USB3 and SSD, but the two aren't related in any ways.

Also, in my experience it is absolutely untrue that the difference between SSD and 'USB3' (as you call it, though you probably mean an external HDD drive), is 'minor'. It is not minor at all, a claim supported by millions other people, including manufacturers such as Apple, Kingston, etc. Try starting your Mac from an external HDD drive and an external SSD, the difference is enormous.

For clarity: I have the old BB on an internal SSD, I am downloading the upgrade, and want to install it on an external SSD. But none of that stuff matters. I wasn't discussing what are the faster drives.
