Conclusion

The Caviar WD1000BB delivers heat and noise levels on par with that of its predecessor, the WD800BB. Though it doesn't plumb the depths like drives from, say, Samsung, idle and seek noises nonetheless remain quite unobtrusive. The 1000BB runs warm to the touch after extended heavy usage.

Overall, Western Digital's latest drive is a package that's hard to beat. It delivers the best overall single-user performance one can get from an ATA drive along with respectable performance in entry-level server situations. But perhaps most importantly, the WD1000BB presents users with 67% more capacity than the competitions' current-generation drives. It's hard to argue with that.
