I installed a new 160 GB Intel 320 SSD in my mid-2010 13" Macbook Pro tonight. The computer boots up slowly, hanging up for what seems like a fairly long time on the initial grey screen before the apple logo appears. After that things happen quickly, as expected. It seems that the overall boot up time is noticeably longer than it was with the HD that came with the computer. This seems odd to me from what I have read about SSDs. I used Carbon Copy Cloner to copy my old HD to the new SSD before I installed it. I'm wondering if I need to reinstall the OSX from the original disk to rectify this issue or if there is another explanation. Any help would be appreciated.
