Okay, question here. I had the newer base Mac Mini, with eight gigs of RAM and a crucial M4 256 gigabytes SSD hard drive. In terms of response, it was very quick, apps will open very quickly, and it restarts a good amount of time as well. Recently I picked up a 2010 Mac Pro, the 3.2 Quad core with 12 gigs of RAM. I'm waiting on my SSD hard drive to arrive in the mail, but for now I have the OS installed on the regular 500 GB hard drive. Oh my goodness, it feels extremely slow! I had forgotten how big of a difference the SSD drive makes. Programs take a few bounces to open up, the system takes longer to restart, when you do start it up, it takes longer to load everything up. Is that normal? Shouldn't this Mac Pro feel fast even with a regular hard drive? I know the SSD makes a big difference, but this does not feel like a very fast computer with the regular hard drive. Could it be that I restored the OS from a Time Machine backup? What a clean install make a difference, and make it faster?
