WD Re 4TB 3.5" SAS Datacentre Hard Drive

Western Digital WD4001FYYG RE Enterprise SAS hard drive combines a 32 MB cache with a SAS 6 Gb/s transfer rate and dual stage actuation for lightning-fast performance in demanding server and storage applications. Featuring technologically advanced acoustics to minimise noise, cool drive operation and enhanced reliability features to help protect the Western Digital WD4001FYYG RE hard drive and the data stored on it. Hard Drive Statistics Speed: 7200 rpm Seek time: 5.5 ms avg Cache: 32MB Interface: SAS 6Gb/s (300MB/sec) NCQ How This WD RE Enterprise Hard Drive Protects Your Data Western Digital WD4001FYYG RE include enhanced RAFF technology and sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time, the result is a significant
performance improvement in high vibration environments over the previous generation of drives. ShockGuard instantaneously protects the hard drive against damage from bumps and 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 StableTrac - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations RAFF - Enhanced RAFF technology includes sophisticated
electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives IntelliSeek - Calculates optimum seek speeds to lower unnecessary power consumption, noise, and vibration. Multi-axis shock sensor - Automatically detects 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 - 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 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 RE drives utilize PMR technology to achieve even greater areal density, reliability, and 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 and 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 and format, settings, features, software and other factors.) One gigabyte (GB) = one billion bytes. One terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment.
