Benchmarking and copying large files are the best way to test a system. It
should be reasonably fast, and large files should copy smoothly with no
freezes and very little slowing over time.

I always test new systems this way. Unfortunately, the problem can be
hardware or software drivers.

What kind of controller does the drive connect to? Does the drive have any
reallocated sectors as seen when you look at the SMART data?

Being a Mac, its can be a little harder to troubleshoot since Apple is a
little different than the rest.
