Western Digital promulgated today the WD Se SATA 3.5-inch standard hard drive, which offers up to 4TB of storage space.
While it's not the first hard drive with this top capacity -- both WD and Seagate have had other 4TB hard drives -- WD verbalizes that the new WD Se is the first that's designed for scale-out data center deployments, yet is still affordable. The hard drive fortifies the latest SATA 3 (6Gbps) standard, comes with 64MB of cache memory, and spins at 7,200rpm.
According to WD, the new hard drive uses enterprise components and technologies to offer reliable always-on operation. For this reason, the new hard drive works best inside a storage system, such as a NAS server, where data needs to be available 24 hours a day, 365 days a year.
WD verbalizes the WD Se hard drive undergoes at least 5 million hours of functional and thermal testing and more than 20 million hours of additional testing under actual workloads

Dual processor and dual actuator technologies to increment the processing power and to ameliorate head positional precision over the data tracks.Enhanced Rotary Acceleration Feed Forward (RAFF) technology that includes sophisticated electronics to monitor the drive and rectify both linear and rotational vibration in authentic time. StableTrac technology that secures the motor shaft at both ends to reduce system-induced vibration. Multi-axis shock sensor that automatically detects even the subtlest shock events and compensates to protect the data corruption.
RAID-concrete, time-limited error recovery (TLER) technology that obviates drive failure caused by the elongated hard-drive error-recovery processes.
Dynamic fly height technology that adjusts each read-indite head's fly height in authentic time for optimum reliability.
The new WD Se is available now in 2TB, 3TB, and 4TB capacities slated to cost between $160 and $310. The hard drive comes with a five-year warranty.
