I just installed a cheap optibay (made by nimitz on ebay) with a 60gb OCZ Vertex 2 SSD in my Macbook Pro 13 (2010). I've got a 500gb hitachi HDD in my main drive slot. I formatted the SSD and installed a fresh copy of Lion onto the SSD from the HDD. Afterwards, it took more than 2 minutes to bootup and each app I loaded took well over 30 seconds to load, often making the system unresponsive for that period of time. I thought it might be a problem with the SATA connection, or the connection from the Optibay to the logic board so I opened it up and disconnected and reconnected those cables. After I did that, the computer took the expected 13ish seconds to boot, but when trying to open apps still took well over the expected time to load. I did a second reinstall of Lion, this time using a bootable usb drive and got the same results. When running DiskSpeedTest I consistently get write times of ~210 mb/s and read times of ~250mb/s, however, when trying to copy a large file to the ssd, I see lots of hangups (copies some data, then stops, then copies some data, then stops, etc.). I have also tried resetting the PRAM and NVRAM using the command-option-p-r on bootup method but doing so made the keyboard and trackpad unresponsive at the login screen. I'm wondering now if it's something I did wrong in the installation, a problem with the SSD, or issue with the logic board's connection to the Optibay. Any input is appreciated! EDIT: Does anyone know if it's a problem with the SSD not getting enough power? I think I am going to swap the SSD to the main drive slot and the HDD in the optibay tonight to see if that does anything.
