After bumping its Thunderbolt and regular MyBook line with a couple of extra terabytes, Western Digitalturned its attention to its shiny MyBook Studio offerings to kick those up a notch too. WD's family of premium aluminum-clad drives finally gets USB 3.0 across the line, along with a new top-of-the-pack 4TB capacity model. All the Studio drives feature WD Security, seamless integration with Time Machine and a 3-year limited warranty. Pricing for the 1TB, 2TB, 3TB and 4TB drives are $159.99, $189.99, $239.99 and $299.99 respectively. Western Digital says they'll continue to offer older USB 2.0 and FireWire 800 models, just in case you're still struggling along with a storage-starved relic from the past.
