Media (films/tv) on two older WD 2.5" drives (one 1TB Elements, one... much older 320GB WD). Both formatted as Mac OS Extended (Journaled). Both drives only have about 50GB free. Will buy a new 2TB WD Elements tomorrow. How long to transfer (one at a time) a total of 1.2GB files across? Will be using a base M1 MBA, new drive directly commected vis USB C, older drives (one at a time) connected via USB A + with A-to-C adapter.
One hour? Three hours? I'd like to use exFat so my housemate can use the drive. Can I still do that on silicon? Any real downside to that format?

Not sure how long it would take to complete the process. I only use rCLspinnersrCY for TM these days but TM is very slow anyway and not a useful guide here. ThererCOs no problem formatting drives as exFAT using DU on a M1 Mac. IrCOve done that several times since IrCOve had my M1 MBP.
ExFAT is not as robust as say APFS, e.g. It doesnrCOt support journalling. I found this article on Reddit which may be helpful.

For spinners, I'd ballpark 100MB/s, or 40MB/s if they're connected
via USB 2 (the 320GB might be if very old).

And bear in mind that even if the disk drive supports USB 3, the cable
might not. A USB A plug on a cable that supports USB 3 will usually
have blue plastic in the plug.
And many USB C cables only support USB 2 speeds, especially if they're
sold as charging cables.

Not here. Maybe you mean the 14" or 16" MBP? I don't think the 13" MBP has one
on that side, either.
