As you can see, dual-core idea in Intel’s CPU and AMD is copied for a few product, like harddisk for the example. 2 processors for processing datas is a solution that has been applied by Western Digital for RE3 series (enterprise). It is claimed the solution will increase the work until 20% compare with the usual harddisk. This RE3 series is designed for workstation environment so it has “heavier” specifications.

Usually a harddisk is supported with anti-crash system to prevent the head from broken. For this RE3 series, WD uses multi-directional censor that can detect shock more detail. Another important technology is RAFF to correct the vibration because the disk’s rotation, error recovery in RAID mode, and the save position control on motor head handle.
