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?
