RE3, 8.89 cm (3.5 ") , 250 GB, 1.2 million hours MTBF, 16 MB Cache, 7200 RPM, SATA
WD RE3 drives combine 16 MB cache with SATA 3 Gb/s transfer rate for lightning-fast performance in demanding server and storage applications. Technologically advanced acoustics minimize noise. Cool drive operation and enhanced reliability features help protect the drive and the data stored on it.
Key Features
Dual processor - Twice the processing power results in a 20% performance improvement over the previous generation.
RAFF™ - Our 4th generation RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration simultaneously, in real time for up to a 60% performance improvement in high vibration environments over the previous generation of drives.
IntelliSeek™ - Calculates optimum seek speeds to lower power consumption, noise, and vibration in active seek modes without degrading performance.
Multi-axis shock sensor - An additional 3rd sensor has been added to automatically detect subtle high frequency shock events in all axis enabling compensation 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.
3rd generation dynamic fly height - Each read-write head’s fly height is adjusted in real time for optimum reliability.
Thermal extended burn-in test - Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.
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.
Perpendicular Magnetic Recording (PMR) - WD RE3 drives utilize PMR technology to achieve even greater areal density.
Ideal For
Ideal for servers, video surveillance, and other demanding write-intensive applications.
