RE 250GB Serial ATA II 16MB 7200RPM 20pk
The best combination of high-reliability and high-capacity, combined with a 5-year warranty make these the perfect solution for your enterprise storage needs.
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.
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.
SATA-specific Features:
FlexPower™– connector technology that accepts power from either industry-standard or new SATA power supplies.
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.
Ideal for:
- Servers
- Network attached storage
- Scientific computing
- Life sciences
- Video surveillance
- Enterprise backup
- Document/image management
- Audio/video media applications
- Other demanding write-intensive applications
- Note: For high performance desktop applications, consider WD Caviar SE16 drives.
