Hi, I want to upgrade my wife's Mac Mini (2007, 1.66 GHz Core Duo, model T2300) with a new HDD. I've done that a couple years back, but times were less complicated. Here are my questions: 1) I hope a 7200 rpm drive will improve performance, without generating more noise than a 5400 rpm drive. Is that a correct assumption and would you recommend that? 2) Looks like many of the 500 GB 7200 rpm drives are SATA II. Will that be compatible with the plugs in the machine? Will I have to set any kind of jumper pins (I've never done that, though)? 3) My plan is to naturally do a time machine back up of the current drive to use it to build the new one. However, I still need to install Mac OS X Snow Leopard. The Mac mini came with a Tiger install disc. How do I get to SL with the least trouble? Do I need to start with the original Tiger disc, then use the Leopard disc and finally upgrade with the SL disc or can I use the SL disc right away? Many thanks!!
