Two weeks ago, word leaked that Western Digital was on the verge of releasing a new hard drive with a whopping 2TB capacity. Now it's official. WD has taken the wraps off its third-generation GreenPower drive and a new storage capacity milestone: two terabytes. This latest Caviar Green gets to 2TB by way of four 500GB platters, each with an areal density of 400Gb/in².
As is customary for its power-efficient GreenPower drives, Western Digital isn't talking specifics when it comes to spindle speed, only saying that it's similar to that of current Caviar Greens. That's code for close to 5,400RPM. But even so, this latest Green's high areal density, combined with 32MB of cache, should make for decent performance.
Western Digital says 2TB Caviar Greens will ship this week, so expect to see them pop up at e-tailers like Newegg soon. This next step up the capacity ladder won't be cheap, though. WD's suggested price for the drive is a whopping $299, which will get you two 1.5TB Barracudas (and a ticket to the firmware upgrade circus). Stay tuned for an in-depth review of the Caviar Green 2TB.
