I am thinking about tackling a project where I open up my late 2012 iMac and installing the same SSD drive I have connected via USB 3.0 (which is what my iMac is currently booting to) into the current HD slot.
My question is…by installing the same SSD into my iMac internally, should all work okay? (I am hearing something about issues with TRIM and perhaps miscalculating heat.) Second question is…will it perform any better?
The reason I ask is that I notice with my current setup (SDD is external and connected via USB 3.0), my iMac occasionally stalls for a split second or sometimes I get the spinning beach ball for several seconds.
Opening up a late 2012 is not an easy task. So, I don’t want to do this unless I will see significant performance improvements.
Any suggestions before I proceed? Thanks.
