Your notebook’s hard drive is dead? All those drives sold out there too small to store your porn collection? Then Hitachi’s here to save you. The company’s new Travelstar 5K750 (5400RPM; 8MB buffer) and 7K750 (7200RPM; 16MB buffer) have been announced this morning, and they’re the company’s first to feature Advanced Format.

They’re also the industry’s largest drives in a standard-height form factor, cramming up to 750GB (375GB per platter) into a conventional 9.5mm shell that’ll slip into just about any laptop made in the last decade. Western Digital may have their own version of 1TB laptop drive, but that’s a 12mm height drive, which not all laptops will willingly play along.

At any rate, the drives will also be available in 500GB and 640GB sizes for those who can’t handle three-quarters of a terabyte, and while the 5K750 family is already shipping in volume with a starting tag of $129.99, the speedier 7K750 crew won’t be out until Q1 2011.
