Western Digital plopped itself firmly in the midst of the 2TB HDD battle back in early September, and if you've been holding off on buying your next slab of storage until the benchmarks hit, we're pleased to inform you that the wait is over. The crew over at Hot Hardware slapped both the Caviar Black and RE4 drives into their testing rigs in order to put 'em both through their respective paces. Without getting into the nitty-gritty, both of the 7200RPM drives were mighty quick in real-world use -- not SSD quick, mind you, but pretty darn snappy given the capaciousness. When push came to shove, the Caviar Black managed to pull ahead in terms of raw speed, but given that the RE4 is really an enterprise drive, we doubt you're keeled over in shock.
