WD Black HDD Enhancements Announced

WD has announced updates across the WD Black line of high-performance 7,200 RPM 3.5-inch hard drives. The WD Black family is available in capacities from 1TB to 4TB and is engineered for applications such as workstations, gaming PCs, and all-in-one devices that benefit from higher performance and high capacity. The refreshed drives feature model numbers in the format of WD(#)003FZEX where the third digit represents the capacity in terabytes.

New WD Black 3.5-inch Hard Drives

  • WD4003FZEX: 4 TB capacity, 64 MB cache
  • WD3003FZEX: 3 TB capacity, 64 MB cache
  • WD2003FZEX: 2 TB capacity, 64 MB cache
  • WD1003FZEX: 1 TB capacity, 64 MB cache

According to WD, design improvements made possible through the company’s dual core processor technology have resulted in performance increases that range from a 26% increase for the 1TB drive up to a 48% increase for the 4TB model. WD has also added a new high resolution controller that doubles the processing capacity of the controller itself, which improves tracking precision and thereby speeds up both read and write operations. Each of the drives features 6 Gb/s SATA connectivity.

The updated 2TB, 3TB, and 4TB drives feature StableTrac technology to reduce vibration by tying the motor shaft at both ends to reduce system-induced vibrations which can otherwise affect performance in multi-spindle designs. All four offerings incorporate updated WD vibration control and corruption protection technologies. WD Black HDDs have a 5-year limited warranty.
