The OWC "data doublers" seem to be for the unibody models that come in late 2008. Unfortunately I have an early 2008 MBP. Has anyone successfully swapped the optical drive for an SSD for that model? I was originally going to just replace the HDD but I never use my Superdrive anyway. If I could do that, I'd just get a smaller SSD (128 vs 256 GB) and save some money. I wonder though whether storing my user files on the old HDD with my system files on the SSD would negate some of the speed benefits of switching to SSD? Any help would be appreciated.
