I've installed a Crucial MX200 in my Mac Mini 2011 recently. It flies compared to the OCW Core SSD that was in it!
Really fast boot, applications startup fast (1 bounce).
I choose the Crucial because of durability and long life. It has power loss protection, which I really need over here in Curaçao. Also some other premium features that are in the MX200 made me decide for it over Samsungs offerings.
It's amazing what Crucial puts in their consumer grade SSD's that are normally only in enterprise or pro SSD's.
I haven't performed AHT though...maybe I'll do that later this week... I'll let you know what the outcome is.
