I've had a Mac mini (mid-2011) i5, 8GB, 500 GB 5200rpm since the release in summer 2011 and it's been a great machine. I've never really had any problems. But lately it's been noticeably slow. Not HD failure slow, I don't think, but annoyingly slow. So I decided that I would restore the computer and build from scratch. So I started to move my stuff off of the internal drive, including my 80GB iPhoto library. Moving that iPhoto library to an external drive was giving me around 400KB/s of write speeds. Which is just crazy. It was taking forever. So I check Blackmagic and the internal drive was maxing out at 28.1MB/s write and 30.9MB/s read. Is this normal? Or is it time to finally utilize AppleCare? UPDATE: Just tried Blackmagic one more time and got a max of 35.4MB/s of write. Still not great though.
