Hard drive, Western Digital, 10TB, WD101PURA-64B5KY0

Capacity: 10 TB. Interface - SATA III. Workload: 180 TB/year. Bandwidth: 6 Gbps. Optimization for RAID arrays. Cache memory capacity is 256 MB. Productivity - 7200 rpm spindle. IntelliPower - speed control depending on the load. AllFrame 4K™ - Reduces frame loss, improves video playback, increases the number of bays. IntelliSeek™ - reduces power consumption by optimizing search speed, noise, and vibration. Dynamic altitude control for use in aircraft. Perpendicular Magnetic Recording (PMR) - aligns the magnetization of each bit vertically with the spinning disk to store more data. NoTouch™ - linear loading, isolation of the recording head from the disk to reduce wear. Dual actuator - 2-stage head positioning system: first - directional shift, second - piezoelectric movement for precise position adjustment. Advanced Format (AF) is an efficient media format that increases density. Command Queuing (NCQ) - Improves performance by intelligently ordering input and output requests. PWL - protection against mechanical wear: forced lubrication with uniform distribution when the disk is occupied by a large number of incoming commands. Set-Data Lifeguard™ - data loss prevention, thermal management, error detection and correction, repair of problem areas. Hot swap. Hydrodynamic Bearings (FDB) with high viscosity grease provide increased non-operating impact resistance, speed control and improved acoustics.
