The drive for more storage

Western Digital has expanded its award-winning WD Black line of performance hard disk drives with the introduction of a new model with up to 6 TB of storage capacity.

The company described the 3.5-inch hard disc drive, which operates at 7,200 revs per minute, as the perfect drive for personal computer gamers and professionals in need of high-volume and high-performance desktop computer systems and work stations.

Western Digital said, in a press statement, that the WD Black 6 TB drive was up to 29 per cent faster than the its previous large capacity drive, the WD Black 4 TB model, in maximum data rate throughput. It was 10 per cent faster in testing done by PCMark Vantage.

Western Digital said the new WD Black hard disk drives combined a 128 MB cache, dual stage actuator technology, SATA 6 gigabits per second (Gb/s) interface, and an integrated dual processor to deliver ultimate performance in a maximum-capacity drive.

"Combining maximum system performance with generous capacity, the expansion of WD Black to 6 TB allows gamers, enthusiasts and creatives to push the boundaries of personalisation without compromise," said WD storage technology group vice president Cindi Grace.

"In choosing WD Black hard drives, WD desktop customers get the best possible mix of capacity, performance and reliability to handle intense desktop computing with ease."

WD Black 6 TB hard drives feature StableTrac Technology which secures the motor shaft inside of the hard drive to increase reliability and help reduce impact due to system-induced vibrations from other components. By stabilising the spinning platters inside the hard disc drive mechanism, Western Digital said, the WD Black drive results in more accurate tracking in a particular sector during read and write operations, optimising performance and reliability.

The new hard disc drives also have Dynamic Cache Technology which the company claims improves caching algorithms in real time to allocate and optimise the data cached between reads and writes. This movement of cache for read data helps to reduce congestion and increase overall performance.

A dual-core processor offers twice the processing capability as a single-core processor to maximise drive performance for faster read and write speeds.

At $489 they might sound expensive, but when you work out their cost per GB that's not bad. The WD Black 6TB comes with a five-year limited warranty.
