I see the spinning disc much more now than I ever used to. Still on SL 10.6.8, and MBP early 2011, 2.3 GHz dual-core i5, 320 GB hard drive, 4 GB RAM, but opening browsers, whatever, I didn't always used to see this unless there was a glitch or something in maybe Photoshop, but now it's a regular player. Anything obvious I can do so speed things up or is it the age of the laptop now?
