Key Features
Reliability in high duty cycle environments - Utilizing enterprise-class manufacturing processes, these drives are designed with enhanced reliability in a 24x7, high duty cycle environment.
Fast - With a next-generation SATA interface, up to 3 Gb/s data transfer rate, native command queuing (NCQ), and 16 MB cache, these drives deliver optimum performance.
Built to last - Made for years of high-performance operation around the clock. Reliability demonstration testing indicates a mean time between failure (MTBF) of one million hours.
RAID-specific time limited error recovery - Improves error handling coordination with RAID adapters and prevents drive fallout caused by extended drive error-recovery processes.
Fluid dynamic bearing (FDB) motor - Improves hard drive reliability; reduces heat, vibration, and noise.
Improved power controller - Consumes less power and generates low heat.
Data Lifeguard Tools™ - Software utility that works in conjunction with the embedded Data Lifeguard™ features (including shock protection, an environmental protection system, and embedded error detection and repair features) to make hard drive installation, management, and diagnostics simple and worry-free.
Hot plug support - Allows swapping of hard drives without having to power down the system or reboot; promotes system design flexibility, data availability, and serviceability.
Backplane compatibility - Uses the SATA industry standard connector which includes alignment ears and 3-stage electrical mating sequence, designed specifically for backplanes and hot pluggability.
SATA latching connector - Provides a secure connection between the hard drive and the cable connector via a locking latch mechanism.
