    Hi folks, I've dealt with this for a while now but I'd love to figure it out:

    I have a 2008 MBP-aluminum (the last refresh before the unibody). About 3 months ago I ordered the PATA drive tray that allows you to remove the optical drive and replace it with a SATA hard drive. My current configuration is a 128 SSD in the primary SATA slot and a 640GB-5400rpm drive in where the optical drive used to be.

    Here's the lame issue. I'm getting normal write speeds 50-70MB/sec but super slow read speeds -- like 15MB/sec max.

    The optical drive on this model has a PATA connector but the drive tray (i bought on ebay) has a PATA to SATA converter built in.

    Why the slow reads and normal writes? You'd think that if the PATA to SATA was junk the writes would be slow too?

    Follow normal diagnostic procedures. Figure out whether it's the drive or something else. Move things around and retest.

    Other than the obvious, no, I don't have any ideas.
