Definitely seeing some variability on my Kingston drive (expanded results attached, at 0% results vary from ~140 to ~540); much less variability on the 2nd drive.

Tried running Spinrite but it just returns an error - is this expected (e.g. due to GPT partitions)?

Yes. SpinRite does not currently work with GPT. Steve is actively working on SR 6.1 right now which will be compatible.

Yes. SpinRite 6.0 does not handle GPT. Hence the error. SpinRite 6.1 will be GPT compatible.
