I had the same experience. The WD scorpio blue was loud and slow. Upgraded to a Hitachi 500 GB 7200 rpm that was pulled from a Mac mini. Dead quiet just like the stock 160 GB 5400 I had, and very fast to boot.
There's a reason why Apple goes with them.![]()
Really?
The 320GB Hitachi I pulled from my 2010 MBP was the loudest HDD I'd ever heard.
The SSD I have now is dead quiet.
