Western Digital Caviar GP hard drive
 

There's more to the Caviar GP than its Birkenstocks, too. The drive packs a mind-bending 250GB per platter and is available in capacities up to a cool terabyte, making it the biggest drive in the Caviar line. There's a catch, of course. While most desktop drives spin at either 5,400 or 7,200RPM, the Caviar GP's spindle speed lies somewhere between the two, and Western Digital won't say exactly where.

With its spindle speed shrouded in mystery, we couldn't help but wonder whether the Caviar GP's performance leans more toward the Tesla Roadster or the Toyota Prius. And what does a slower spindle speed mean for power consumption and noise levels? To find out, we've tested the drive against 20 others, with surprising results.
