I have the final Powerbook 1.67ghz DDR2 HRDL blah blah blah machine. Love it. Anyway, the OEM UJ 846 is slowly giving up the ghost so I bought an optibay/SATA to the IDE. Actually I don't know if it's a real Optibay, probably a Chinese knockoff, but I don't think it matters much. I have a new 320gb PATA HD in the powerbook, but thinking about putting in a PATA SSD, like 32gb, and dropping a 1 TB into the optibay. Or should I put an SSD in the optibay, and keep the 320gb HD where it's at? Does anyone know if the already slowish IDE HD bottleneck is the same for the IDE optical drive on the Powerbook? I have no idea. Just want to optimize the machine.
