And, it doesn't end there, I remember I bought an Optibay years ago for My Pismo, it fitted, was a SATA to PATA Optibay and it worked well for booting the System of, the strange thing was though that if I booted of the normal HD and copied Data to or from the Optibay the data was many times corrupted.
This is probably not an issue anymore since there is no Data conversion needed, it's all Sata.
