I know what the numbers say: SSD is faster than 7200rpm which is faster than 5400rpm. But I want to know about real world difference in an HTPC. My Mac Mini is connected to my TV and only runs Plex. It currently has 4gb of ram, 9400m, and a 5400rpm harddrive. All of my media is stored on my NAS and speed has never really been an issue for me, sometimes the menus take a little more than a second to load- not a big deal. I just acquired a brand new 7200rpm drive and was thinking about putting it in the mini. Then I began to wonder if it would even be worth my time and effort to do it. I'm pretty comfortable with the upgrade as I've done it on plenty of mini's but my question is more of: Would I even notice the speed increase? Even if I were to get an SSD (would only need a small 32gb one), would I notice any speed increase on that? Let me know, those of you who upgraded your HTPC from 5400 to 7200/SSD or even if you upgraded your 7200 to SSD. I'm probably going to end up doing it anyway but I'd still like to hear what you guys have to say. Thanks.
