I had a WD Scorpio Blue 500 GB a few months ago but the constant head parking and clicking was driving me crazy so I put the stock drive back in. I figured I'd wait a few months and try again when I upgraded the RAM. Well I'm ready to upgrade now and I'm wondering if I should go with the WD or Hitachi drive. I'm not to worried about the speed of the drive so I'm fine with a 5400. I do want something that's as quiet as the stock drive tough. Do the WD Scorpios still suffer from the constant clicking and head parking or would I be better served with a Hitachi or Seagate drive. Thanks No one?
