Western Digital hard drives in the market are available in different colors of black, red, blue, green, purple etc, every color has its own story of power consumption, storage and speed. Just as we look forward to the next color, Western Digital does not follow the routine and launch its new product, namely Re +, mainly for data centers, although brought a “Plus” mark, but in fact cannot be regarded Re + Re upgraded version, but low-power version, 6TB capacity version consumes only 6W, but at the expense of reducing power consumption, they also reduced the speed of 7200RPM to 5760RPM.
Western Digital RE+ Hard Drives: 6TB, 5760RPM and consumes only 6W
In the current era data centers need a huge number of hard disk array, so the hard drive power consumption will directly affect the cost of data center operations, Western Digital Re + Series drives intention is to reduce the TCO (Total Cost of Ownership).
The current series of hard drives Re hard drives while reading consumes 9.4W, random read and write can reach 10.6W, stand there 7.5W. The launch of Re + Series drives uses the SATA 6Gbps interface, the physical dimensions are 7x24x365, 1.2 million MTTF reliable, trouble-free operation, the maximum capacity of 6TB, sequential reads consumes 5.8W, sequential write power consumption of 6.2W, random read write power consumption of 5.5W, standby power consumption of 4.6W.
Of course, Western Digital has no black technology, reducing power consumption is actually by reducing hard drive speed achieved, Re series standard speed is 7200RPM, and Re + series reduced to 5760RPM, transmission speed from 225MB / s reduced to 175MB / s.
Other datacenter-class features with the WD Re and WD Re+ products include:
Vibration protection – Enhanced RAFF technology monitors the drive and corrects both linear and rotational vibration in real time. The result is 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 – Our 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.
Western Digital Re + Series drives come with a 5-year warranty. Western Digital Re + 6TB hard drive will go on sale in the next quarter, specific ship date and price are unknown.
