Wanted to speed up my iMac performance. The RAM was already maxed, so the only thing left to do was upgrade the what's drive to an SSD.
It was pretty smooth. Much easier than I thought it would be.
I think it's worthwhile to upgrade the ram & SSD on your older Mac before going out and buying a new one. Plus, the new designs are not upgradeable like the older ones.
