- Drive RPM is not a performance measurement anymore. With larger capacity drives, the data is more dense meaning more can be read at a given RPM.
-For reasons beyond me, external drives are significantly cheaper than internal and you can remove the drive for internal use. Google the external drive to try find out what is inside. I recently purchased a WD Elements 8TB for $249 (AUD) and the internal drive is actually a HSGT that retails here for about twice that. Its now been shucked and is my main media storage drive
