Today WD, a Western Digital company, announced the worlds most power-efficient, 6TB HDD for datacenters, the WD Re+ hard drive family. The new drives only consume 6 watts per 6TB. WD has also announced that the WD Re And WD Se will now be expanding to include a 6TB model as well.
Power consumption is a big concern in today’s large web-scale cloud infrastructure. Power consumption is also a part of the total cost of ownership formula (capacity, price, power consumption and the relationships between these variables). WD’s new Re+ drives only consume 6 watts per 6TB, a power consumption that could save customers tremendous amounts per year. The drives features a dense 5-platter design to achieve its low pwer consumption, reliability, high capacity, and affordability. Not only will customers see a higher energy efficiency with the WD Re+, they will also have the proven reliability they have come to expect from the WD Re line.
WD Re+ and Re datacenter-class products features include:
- Vibration protection – Enhanced RAFF technology monitors the drive and corrects both linear and rotational vibration in real time, resulting in a significant performance improvement in high-vibration environments over the previous generation of drives.
- Dual actuator technology – A head-positioning system with two actuators improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine-tune the head positioning to a higher degree of accuracy.
- StableTrac – The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations.
- Multi-axis shock sensor – Automatically detects the subtlest shock events and compensates to protect the data.
- RAID-specific, time-limited error recovery (TLER) – Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives.
- NoTouch ramp load technology – The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
- Thermal extended burn-in test – Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.
- Dynamic fly height technology – Each read-write head's fly height is adjusted in real time for optimum reliability.
- Dual processor – Twice the processing power to maximize performance.
- 3D Active Balance Plus – Enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time.
