Hi. I've got a mid 2007 alu iMac and was thinking of installing an SSD as the boot drive to try and revitalise the machine somewhat. The SSD will be for all OS/aplications, all data is on external drives. Now I know people say it improves boot time/app loading time etc but my question is this. The machine is on 24/7 so boot time is irrelevant. The apps will open much faster but if the apps are still having to fetch data off the external drives will it really be worth it? Will I be running much faster or not? Opinions please.
