SanDisk Extreme external SSD running super slow on new Macbook 16" M1 Max

I noticed in early December that my Sandisk Extreme SSD's (APFS formatted) are running abysmally slowly on my new M1 Max. Sandisk has no solution. Hoping for a software fix or a workaround.

MacBook Pro 16″, macOS 12.1

You do not mention the interface or adapters involved...?

The transfer speed is going to be limited to the lowest common denominator.



Try a different drive with a native interface and compare your results
