Western Digital ha presentato una nuova gamma di hard disk chiamata RAID Edition 3 (RE3), che rimpiazzerà la serie RAID Edition 2. Questa nuova serie di dischi sono indirizzati al settore enterprise. Rispetto alal serie RE2 Western Digital afferma che il divario prestazionale è varia dal 20% al 60%.
Questo è stato possibile grazie alle tecnologie Rotary Acceleration Feed Forward, Time-Limited Error Recovery e NoTouch grazie alla quale le testine non andranno a toccare i piatti.
I dischi sono disponibili in tagli da da 250Gb ($79), 320Gb($89) e 500Gb ($199).
Riportiamo i lcomunicato stampa originale:
"LAKE FOREST, Calif. - June 19, 2008 - Addressing the growing enterprise market for highly reliable high-capacity storage, WD (NYSE: WDC) today announced it is now shipping the new WD RE3 SATA hard drives, the company´s latest generation of "RE" family drives. As data centers become larger and more complex, WD´s third-generation high capacity enterprise SATA hard drives enhance vibration and shock tolerance and deploy new electronics to increase performance approximately 20 percent and by as much 60 percent in high-vibration environments.
"WD has continued to leverage its extensive experience gained from previous generation enterprise drives, as well as our enterprise-class WD VelociRaptor™ drives, to develop a hard drive perfectly suited for servers, network attached storage and storage networks," said Tom McDorman, vice president and general manager of enterprise storage solutions for WD. "WD´s RE3 family offers the best combination of enhanced features, superior reliability, and optimum performance for enterprise applications."
In line with the WD RE drive heritage, WD RE3 drives feature 1.2 million hours MTBF, native command queuing (NCQ), time limited error recovery (TLER), and an extensive and enhanced testing process to ensure long-term reliability for demanding enterprise applications.
WD RE3 Features
- Dual processor - Twice the processing power that results in a 20 percent performance improvement over the previous generation.
- RAFF™ technology - Resulting in up to 60 percent performance improvement over previous generation drives, WD´s fourth-generation RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration simultaneously, in real time for maximum performance in high vibration environments.
- IntelliSeek™ technology - Calculates optimum seek speeds to lower power consumption, noise and vibration in active seek modes without degrading performance.
- Multi-axis shock sensor - An additional third sensor has been added to RE3 models to automatically detect 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.
- Third-generation dynamic fly height - With this next generation dynamic fly height technology, each read-write head´s fly height is adjusted in real time for optimum reliability.
- Thermal extended burn-in test - Extended burn-in testing with thermal cycling added to ensure only the most robust drives are produced as RAID Edition.
- 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.
