I reverted back to a 12" Powerbook because I couldn't stand the size and lack of fw in the original unibody MB, and now want to pump as much power as possible out of it. I need to upgrade, I don't trust it's four year old original 60gig hard drive. So I held on to my rarely used "SmartDisk" cd burner that was an Apple give away with my original PowerBook Titanium 400mhz buy in August 2001. It's a tray loading ATA CD FIREWIRE burner. Those original PBs did not have cd burners and this was Apple's way of making nice. I was looking at it the other day and pried it apart and realized it was just a simple enclosure for any PATA tray load burner. So now, I'm thinking about getting an SSD drive plus an OPTIBAY SATA drive for the 12" POwerbook and losing it's combo drive altogether. If I get a blu ray tray load burner I'm pretty sure it will fit in this firewire enclosure. If Apple updates us to be able to burn bluray, it will also be portable and I can switch it with my intel machines. Plus I will be able to carry it around in case I need it with the 12" Powerbook, that will have two hds in it to speed it up. What do you guys think of this idea? The firewire "SmartDisk" unit is very reliable I even bought a couple for a few friends of mine a couple of years ago. I like the bootable aspect of firewire on a burner, instead of everyone having USB externals.
