The SSD is probably your best bet. If Apple spec'ed a 4200RPM drive in there,
it had to be because the 5400 caused heat problems. Another caveat: Apple has
started tying into the internal thermal sensor of some of their internal
drives, but the pins are different between brands -- so if you buy a different
brand to replace a dead drive, you may discover the thermal harness in the Mac
doesn't fit the drive. Apple actually makes different harness cables for the
same model Mac, depending on whose drive they intend to use at any given time.
