Western WD1003FBYZ RE4 7.2K 3.5″ Enterprise SATA Hard Disk Drive

Capacity: 1000GB
Spindle Speed: 7,200RPM
Interface Type: SATA
Disk Size: 3.5″x1.0″ (LFF Hard Drive)
Sustained Throughput (MBps): 128
Average Seek Time (read/write ms): 
Electrical Interface Speed: SATA 600 – 6.0Gbps

Massive capacity: 
WD RE4 Enterprise SATA drives are available with up to 2 TB of cavernous capacity.

Dual processor:
With double the processing power, WD RE4 boasts the highest performance of any drive in the WD RE family. 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.

Dual actuator technology:
A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy. (2 TB only)

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.

IntelliSeek™
Calculates optimum seek speeds to lower 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. 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.
Thermal extended burn-in test:
Each drive is put through extended burnin testing with thermal cycling to ensure reliable operation.

Third generation dynamic fly height: Each read-write head’s fly height is adjusted in real time for optimum reliability.

24×7 reliability:
With 1.2 million hours MTBF (tested at 100% duty cycle), these drives have the highest available reliability rating on a high-capacity drive.
