Hi. My in-laws owns a Mac Mini Primo 2009 and they complain about it being very slow. I have already upgraded the machine from 2GB RAM og 4GB RAM and from the default 5400RPM HDD to an 7200RPM HDD. The machine has been formatted and reinstalled with the newest OS available but it is still slow. I was wondering if they will benefit from upgrading the HDD to an SSD option. I don't know a lot about harddrives so i'm worried that the SATAII will slow the SSD down to a point that it's not running faster than the 7200RPM that's in the machine now? What do you guys think?
