Hi Filip Parol & Chandra Sekaran

Watch out as not all SSD drives are created equally.  Some of the "consumer" level SSDs perform very well when there is one process writing/reading to the drive.  But not when there are multiple processes trying to read/write concurrently.  And distributed parallel solving means that if run on N cpu cores there are N solver processes usually all trying to read/write at the same time.  You may want to search for any publised tests of the concurrent process read/write tests of the specific SSD on your system.  Or ask your IT departments hardware people if you happen to work at a company/university that has a IT department.  Or test it your self by solving a medium sized model with 1 cpu core, then 2, then 4 up to the limits of your system.
