What SSD models are suitable for optical drive replacement?
This guide explains how to install a second hard drive (by replacing iMac's optical drive).
It's Crucial m4 256 GB SSD (model № CT256M4SSD2) on the picture. (BTW there is another Crucial m4 256 GB SSD - CT256M4SSD1. But as I can suppose it's impossible to use it for replacement.)
So, what other SSD drives are suitable for this replacement? Any suggestions? How to pick the right one?
Question 2: Can I use only this SSD as system hard drive?
Is this a good question?
