Hi everybody. I have a simple question to suppress any of my doubts. If i replace the superdrive of my Imac 21.5’’ with a SSD, will I be able to install the OS on it and at the same time keep the HD as secondary internal memory?
The BUS speed on the optical drive is slower than the main BUS so I would switch the drives. You did not tell us which iMac you have, so I cannot give you full details. UPDATE \Now that I know your machine, my answer is different. Use this guide: Installing iMac Intel 21.5" EMC 2428 Dual Drive Kit
