Good speed, cool and quiet 12/01/2009
I bought this drive as a low-cost replacement for a slightly smaller and supposedly faster WD Caviar Blue (320 GB, I don't recall the exact model). I've become increasingly a fan of quiet and power efficient components where they don't sacrifice performance unduly, but I was concerned that the slower spindle would hurt performance in some cases. This hasn't been the case in typical usage, where the extra cache and the additional "intelligence" designed by WD seems to more than compensate for the power-saving features. Maybe a benchmark would disagree, but even in gaming I don't think a user would be able to tell the difference. This thing is also far quieter and noticeably cooler than the WD blue it replaced.
If you're worried that the WD greens are significantly slower than the blues or even the blacks, don't be. Your typical desktop computer idles far more than it's active and even if benchmarks show the greens to be a tad slower I don't think most users will find a difference in practice. So save a few watts off your power bill and get this excellent drive.
