I also had one of the first generation 1TB 2,5" drives, it is aso 12.5mm. It took me a while to find an external case that fits because most are 9.5mm (the "standard"). I would just keep it at 9.5mm which allows 99% of the laptop drives. The WD Velociraptor is also 12.5mm but it's not supposed to go into laptops because it generates heat like enterprise 2,5" disks. Also, any SSD, even the crappy 32-64GB ones, will give you a better experience than a Velociraptor. I have one in my test bench system because it's just obselete nowadays.
