I will execute my ISQL cases with 2.5 SS and 2.5 SC on a real HDD. We
will see...
- 1 ISQL 1 DB
2.5 SS - 3:03
2.5 SC - 3:08
- 5 ISQL 1 DB
2.5 SS - 11:13
2.5 SC - 7:28

I'm asking because some application might load same library using different
paths via symlinks. And at least Windows (haven't tested Mac or Linux) is smart

My first reaction was that HDD is still the more common base for
systems, and for large volumes of data I think that will be the case for
a while yet? But I've been adding SSD's as the boot disk on my servers

Correct?
Yes. But 2.5 SC beats them all. I made a graph from the results. The
numbers are seconds and the smaller is the better.

That's worth testing for particular SSD. For example my SSD
