WD RE 7200 RPM Enterprise SATA hard drives are packed with performance and reliability features making them the perfect solution for enterprise storage and servers, video surveillance, and other demanding write-intensive applications. With a designed, manufactured and demonstrated MTBF of 1,200,000 hours at 100% duty cycle in nominal enterprise conditions, 64 MB cache, and best-in-class vibration tolerance, these drives are the ultimate in Enterprise SATA storage.

Product Features:

• Rotary Acceleration Feed Forward (RAFF) — These drives employ RAFF technology to maintain hard drive performance in high vibration environments through adaptive compensation of the servo system
• Native Command Queuing (NCQ) — Performance of a random I/O workload can be improved through intelligent re-ordering of the I/O requests so they read/write to and from the nearest available sectors and minimize the need for additional disk revolutions or head actuator movement. This improvement can be achieved though Native Command Queing (NCQ) , which is supported by these hard drives.
• MicroFemto Slider — These drives incorporate the next generation of femto slider form factor in which the read/write head is mounted on the small, lightweight microfemto slider that allows the head to move more quickly from track to track on the disk.
• Staggered Spin-Up — Next generation SATA 6 Gb/s feature that allows the system to control whether the drive will spin up immediately or wait until the interface is fully ready
