SSD, either instead of optical drive or as second SATA device

hi there,

my optical drive was not really working from the beginning, so getting rid of it would be a good idea. the optimal solution would be to insert a SSD instead of the dvd-drive.

reading this discussion(SSD instead of optical drive), i'm wondering if the same is valid for my older macbook pro / A1150(2006 model). the hdd is SATA, but according to the system profiler, the MATSHITADVD-R UJ-857 optical drive is an ATA device, so that's a completly different kind of interface.

so i guess the only option for using a SSD would be to replace my current 100GB sata with an sata-SSD. or perhaps there is a second SATA interface onboard?

thx & so long
