has updated its line of enterprise hard disk drives with two new models, the MK01GRRB and the MK01GRRR, both packing 300GB of capacity squeezed into a 2.5-inch form factor. Although the 300GB doesn't sound that much bear in mind that these drives have a 15,000 RPM spin speed.
The only difference that we can see regarding the specs of the MK01GRRB and the MK01GRRR is that the latter one has features self-encryption technology. As far as the other specs go, both models feature a top capacity of 300GB, 6.0Gbps interface and 15.000 RPM spin speed, something that you don't see everyday in an average 2.5-inch HDD.
Of course, in order to keep the power consumption at lowest possible value, these drives feature an enhanced power condition state that reduces drive spin in idle state. Both models should start to ship in volume in Q1 2012. Despite Toshiba's claim that they are the first ones with such a drive, Seagate also has its Savvio HDD series with similar, if not identical, specs.
