Seagate today introduced the first in what it expects will be the future direction of hard disk technology, drives that use NAND Flash memory as an extra-large cache.
The launch comes as vendors are experimenting with integrating solid-state, all-Flash drives into their PC disk storage offerings. SanDisk, for instance, recently announced plans for a solid-state drive in 32GB and 64GB capacities.
Such drives offer the potential for "disk" storage that's far quieter, faster and energy-efficient than conventional hard drives. But these benefits are mitigated by their low capacity and staggering cost. To put this in perspective, a 64GB drive is around $900, while 1TB 3.5-inch internal SATA drives are priced at just over $300.
