Today Seagate has announced two new models of its award winning and industry mainstay Cheetah enterprise class hard drives, the Cheetah 15K.7 and Cheetah NS.2. What’s really significant about these models is that they are 3.5” form factor drives in larger than previously available (SAS) capacities. This means that companies with server and storage arrays that already have backplanes and rack sleds for 3.5” drives can be upgraded in capacity without having to be replaced thus increasing the equipments lifecycle.
