HD formats

[inView]

Daft question but does how your format your hard drive have any bearing on speed etc on an external HD on a Mac? New HD for pics, and Wonder if there is any discernible differences for APFS or exFAT?

exFAT is only for temporary file transfers and memory cards. It is a non-journaled system which makes data loss significantly more likely. That is not a problem with your memory card because obviously you are recording to 2 at a time if you care about it at all. I would not store any critical data on it, unless you have very good backups, and you actually should have that anyway.
There is nothing wrong with AFPS other than the fact you are well and truly stuck with Mac for reading and writing it.
There are many factors affecting speed and most obvious ones include drive spec and interface throughput and load.

If your OS can read/ write to an APFS drive, that would be the best option.
