Mac Mini 2011 with Mountain Lion 10.8.2 fresh install, 2.3 GHz i5, 8 GB RAM, 128 GB SSD (Samsung 830). Time from pressing the start button until login window, 25 sec. Seems slow-ish to me. I have seen 15 sec on Youtube with the same specs. I have downloaded Disk Speed Test and got the following numbers: Write 329 MB/s, Read 428 MB/s. The read speed seems slow. Close to 500 seems to be normal if I Google it.
