Western Digital WD4001FYYG RE Enterprise SAS hard drive combines a 32 MB cache with a SAS 6 Gb/s transfer rate & dual stage actuation for lightning-fast performance in demanding server & storage applications. Featuring technologically advanced acoustics to minimise noise, cool drive operation & enhanced reliability features to help protect the Western Digital WD4001FYYG RE hard drive & the data stored on it. Hard Drive Statistics Speed: 7200 rpm Seek time: 5.5 ms avg Cache: 32MB Interface: SAS 6 Gb/s (300MB/sec) NCQ How This WD RE Enterprise Hard Drive Protects Your Data Western Digital WD4001FYYG RE include enhanced RAFF technology & sophisticated electronics to monitor the drive & correct both linear & rotational vibration in real time, the result is a significant performance improvement in high vibration environments over the previous generation of drives. Shock Guard instantaneously protects the hard drive against damage from bumps & vibrations while it is running, this technology enables the WD WD4001FYYG RE drive to achieve industry-leading shock specifications Key Features Dual actuator technology
- A head positioning system with two actuators that improves positional accuracy over the data track (s) Dual processor
- With double the processing power, WD RE boasts the highest performance of any drive in the WD RE family Stable Trac
- The motor shaft is secured at both ends to reduce system-induced vibration & stabilize platters for accurate tracking during read & write operations RAFF
- Enhanced RAFF technology
Includes:: sophisticated electronics to monitor the drive & correct both linear & rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives Intelli Seek
- Calculates optimum seek speeds to lower unnecessary power consumption, noise, & vibration. Multi-axis shock sensor
- Automatically detects the subtlest shock events & 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
- Each read-write head's fly height is adjusted in real time for optimum reliability Thermal extended burn-in test
- Each WD RE drive is put through extended burn-in testing with thermal cycling to ensure reliable operation No Touch ramp load technology
- The recording head never touches the disk media ensuring significantly less wear to the recording head & media as well as better drive protection in transit Perpendicular Magnetic Recording (PMR)
- WD RE drives utilize PMR technology to achieve even greater areal density, reliability, & design margin Active Power Save
- Delivers best-in-class power consumption through advanced WD firmware that conserves power in active seek modes without degrading performance This Western Digital WD4001FYYG RE Stores: Up to 800, 000 digital photos Up to 1, 000, 000 songs (MP3) Up to 100, 000 songs (uncompressed CD quality) Up to 300 hours of Digital Video (DV) Up to 1540 hours of DVD quality video Up to 480 hours of HD video (Examples of the number of photos, songs, videos & any other files that can be stored on a hard drive are provided for illustrative purposes only. Your results will vary based on file size & format, settings, features, software & other factors.) One gigabyte (GB) = one billion bytes. One terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment.
