I'm going from a 320GB iMac to a 120GB SSD + 1TB HD iMac modified by OWC - they put the OS on the SSD for you. Of course not everything on my current drive will fit on the SSD.

Wait times have been drastically reduced, and that SSD breathes new life into a dying laptop. The bottom line is that they’re happy, and I’m happy.

Samsung unveiled quite a few new OEM-based SSDs at the Samsung 2016 SSD Forum in Japan, including new SATA-based 2.5-inch CM871a and PM871a value-oriented SSD based on the new MAIA controller.
