Interpretation of the reliability of the King WD RE3 enterprise hard drive serie
Hard disk , The "business-critical," known for Hard disk There are two series?? RE4 and RE3. They are enterprise-class SATA hard drives, designed for a variety of business-critical applications. Large capacity, high performance, reliability is its greatest feature. Common market is RE3, as is the third generation of hard drives, RE3's market performance, and applications are more mature. Therefore, this highlights the RE3 drives.
1, Western Digital RE3 series significantly improve the reliability of
WD RE3 hard drive with up to 32 MB cache and dual-processor speed, transfer rate of 3Gb / s SATA, enhanced reliability, including fourth-generation RAFF technology, these drives become Server , Storage arrays, video surveillance and other demanding write-intensive applications ideal. It has the following main features:
Large capacity?? WD RE3 Enterprise SATA drives with up to 1 TB of capacity.
Performance?? Dual processor capacity is twice the previous generation product, so a 20% performance increase.
Enhanced reliability features?? Multi-axis vibration sensors and fourth-generation RAFF technology in vibration environments to provide enhanced reliability.
Burn calories extended test?? Each drive cycle through the heat expansion of burn tests to ensure reliable operation.
2, RE3 series of major specifications and features
WD's RE3 specific parameters and characteristics, function follows form.
Third, Western Digital RE3 drives feature
From the perspective of the hardware specifications, RE3 is the single platter 334GB, 7200 switch, use the SATA II300MB / s interfaces, RE3 has 250/320/500GB 16MB cache and 750GB/1TB32MB the five versions of the cache. Most enterprise-class SATA hard drives with the same, RE3 nominal 1.2 million hours mean time between failure.
7200 RPM1TB, has a 32MB cache and 5 year warranty. In addition to 10 000 in addition to switch-level VelociRaptor, this 1TB hard drive called the strongest in terms of running everyday applications, data transmission, when multi-tasking performance in a powerful performance of all.. Because 1TB in a multi-task, excellent performance under high load, makes this product popular workstations and Server Users. Especially, workstations and servers, the storage system is always Disk array Form, while the biggest advantage is: This the error recovery and physical aspects of earthquake resistance is optimized for this market.
From a price perspective, Western Digital is not as big as everyone expected the price increase RE3, by contrast, RE31TB the price has dropped to 800 yuan, for the workstation and server users, no doubt quite worthy. Plus extended warranty for 5 years, for those who need to set up high-performance workstation or server, multi- Disk Array of users, the Western Digital RE3 series is the best choice.

4, RE 3 Application and Case
WD's RE3 products with the EMC Cooperation , Especially in the EMC CLARiiON CX3 / 4 system applications to meet many types of applications. The following diagram models have on the adoption of RE 3.
In addition, Western Digital's RE3 also made site into the fast lane of growth. Chinese road network is a book aimed at users who love traveling by car is built. Therefore, in the course requires a lot of graphic design, more powerful data analysis and throughput in order to quickly build a travel route. Western Digital's RE3 hard drive
time in front of the user, just have the road network needed the book fast processing power. It integrates a dual-board processor, on the Web site users, making access to information, significantly shortening the time. In addition, RE3 is commendable that the full account of the user's data security, which integrates the aforementioned RAID-specific time-limited error correction technology, and design to the impact of adding a multi-sensor, in order to maintain the hard drive running smoothly as possible, thus to ensure the smooth running website.
