Wd re + the new range of hard drives for nas and datacenters
Western Digital, the world leader in storage, launches WD Re +, the new family of hard drives for modern data center architectures with the lowest power consumption in the market, among the large capacity 3.5-inch drives that exist today. In addition, it also introduces two new models for the WD Re ™ and WD Se ™ drives, with 6 TB of capacity. In this way, WD expands its portfolio of solutions, offering its customers the perfect hard disk for data centers based on the intensity of their applications, energy needs and value for money.
In modern data centers, the total cost of ownership (TCO) is shaped according to capacity, price, energy consumption and the relationship between these variables. The WD Re + hard drive offers the best energy efficiency as well as the highest capacity and highest intensity platform available on the market today.
As energy consumption is one of the fundamental considerations in large cloud infrastructures, the WD Re + disk is presented as the perfect solution, since it only consumes 6 watts for every 6TB. In this way, the savings for large infrastructures can be thousands of dollars a year.
"The euro, but also the watt, is without a doubt the main currencies when it comes to modern data centers, " says Matt Rutledge, senior vice president of storage technology at WD. “With the most cost-effective watt per gigabyte ratio on the market and the reliability of WD Re drives, WD now offer with WD Re + the ability to have the best hard drive for high intensity tier 2 storage applications. This type of massive and scalable facilities offer a large number of advantages, as well as a good economic return for the owner of this infrastructure. From WD, we are working to offer this value thanks to our portfolio of hard drives. ”
The WD Re + family, with 6Gb / s SATA hard drives offers a robust five-deck platform that provides an optimal combination of energy savings, high capacity, value for money and reliability 24 hours a day, 365 days a year. Vibration tolerance and Mean Time to Failure (MTTF) are also critical to these applications. WD Re + hard drives offer 1, 200 hours of Mean Time to Failure (MTTF) and a reliable workload rate of 550 TB per year, the highest for a 3.5-inch WD drive. In addition, the improved RAFF technology increases the tolerance to vibrations, another fundamental aspect for this type of environment.
For their part, WD Re drives now offer up to 6TB of storage to meet the demands of datacenter and cloud infrastructures. WD Red are also designed to support loads of up to 550TB in high intensity datacenter applications. In addition, it has a SATA interface with transfer rates of up to 6GB / s and sustained sequential data rate of 225MB / s, offering the performance and reliability required in any data center.
Other features of the WD Re and WD Re + drives include:
- Vibration Protection - Enhanced RAFF ™ technology monitors the disc and corrects both linear and rotational vibration in real time. The result is a performance upgrade in high-vibration environments over previous disk generations
- Dual Actuator Technology - A dual actuator head placement system that improves placement accuracy on data tracks. The primary trigger provides basic displacement through the use of electromagnetic principles. Secondary trigger uses piezoelectric motion to fine-tune head placement for a higher level of precision. StableTrac ™ - 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 crash sensor - Automatically detects and compensates for the finest crash events to protect data
- Time-limited error recovery (TLER), specific to RAID - Prevents the disk from malfunctioning due to the extensive error recovery processes that are common on desktop disks
- NoTouch ™ Loading Ramp Technology - The recording head never comes into contact with the disc, ensuring much less wear on the recording head and disc, as well as better disc protection during transport
- Extended Thermal Test Run - Each disc goes through an extensive test run with a thermal cycle to ensure reliable operation
- Dynamic Flight Height Technology - Each read-write head flight height adjusts in real time for optimal reliability
- Dual Processor - Twice the processing power to maximize performance
- 3D Active Balance ™ Plus - Improved balance control technology significantly increases overall performance and reliability of the hard drive. Disks that are not properly balanced can generate excessive vibration and noise within a multi-disk system, thus reducing the life of the hard disk and overall performance.
For its part, the WD Se line for datacenter offers a combination of performance, reliability and capacity designed for both small and medium-sized businesses and large data centers with large-scale NAS environments. Capacities now go up to 6TB.
