The WD800BB will not remain the flagship for much longer: A new 100 GB drive is coming soon.
The WD800BB is a very affordable drive - it can already be had starting at $ 190. Taking its low price into account, the performance of this drive is quite good. It's temperature is only slightly higher than the 600BB, and surprisingly, both its surface temperature and noise level are even lower than the WD400BB.
Just like with the WD600BB: The jumper settings are printed on the label. Without it, you could not possibly distinguish the WD drives from each other.
