I just installed and Carbon Copied my mac pro system disk to a Raptor 150GB drive because I wanted a speedier system drive. And while booting is faster and it generally does seem faster, when I run a benchmark test in BlackMagics Speed Disk program, this drive runs slower than my WD 500GB RE2 drive by about 20-30%!??! Also, it makes a lof of noise when accessing, which nobody mentioned in reviews. Anything I can do about that? Is it possible maybe to change its physical management somehow? I only see utilities for fiddling with that on PC.
