WD today introduced the WD Re+ datacenter hard drives that feature the lowest power consumption of any high-capacity 3.5-inch hard drive available today.

The WD Re+ hard drive family is the newest component of WD’s portfolio of high-capacity datacenter storage devices. Further expanding that portfolio will be 6 terabyte (TB) capacities for WD’s WD Re and WD Se datacenter product lines.

WD says that the new SATA 6 Gb/s WD Re+ drive consumes only 6 watts for 6 TB. It features a dense five-platter platform and delivers 1.2m hours MTTF, enhanced RAFF technology to increase vibration tolerance and a high-intensity workload and reliability rating of 550 TB-per-year workload.

In addition, WD’s Re platform now offers up to 6 TB for datacenter and cloud storage needs. WD Re hard drives also are designed to handle up to 550 TB per year in high-intensity datacenter applications. They offer SATA interface with up to 6 Gb/s transfer rates and sustained sequential data rates of up to 225 MB/s.
