Curious to know. Been considering an external.  How do speeds of externals compare with an internal SATA SSD? No doubt the externals aren’t as fast as an NVMe m.2, right? 

Internal is and probably always will be considerably faster.

Data transfer will go as fast as the slowest device or bus in the chain 
•    the source disk
•    the interfaces over which the data is moving
•    the destination disk

External interface/connection types:

Thunderbolt
•    Thunderbolt 3 and 4 support speeds up to 40Gbps.
•    Thunderbolt 2 supports speeds up to 20Gbps.

USB-C
•    USB 4 supports speeds up to 40Gbps.
•    USB 3.1 supports speeds up to l0Gbps.

USB-A
•    USB 4 supports speeds up to 40Gbps.
•    USB 3.1 supports speeds up to 10 Gbps.
•    USB 3.0 supports speeds up to 5 Gbps.
•    USB 2 supports speeds up to 480Mbps.
•    USB1 supports speeds up to 12Mbps.

Firewire (6 Gbps)   

Any system that supports either USB 3.0 or higher can easily handle the 900 to 1025Mbps that the drives mention in this thread are capable of.
In actual situations, many of these max speeds are rarely achieved.
