If you’ve been wondering when we might see 3TB drives arriving, the answer is soon. At least according to Dr Geoff Barrall, founder and CEO of Drobo. He says that Drobos will be offering a 3TB drive by April 2010. Drobo uses Western Digital drives, so there’s a good chance that it could mean that Western Digital will be outing some 3TB drives of their own very soon.

Currently Western Digital offers a 2TB Caviar Black 3.5-inch SATA drive. A 3TB, 4-platter drive would need 750GB per platter – a 50 per cent increase over what the Caviar Black has.

With 1TB and 1.5TB drives becoming more popular, it will be nice to make the jump to 3TB. That’s a lot of data!
