Western Digital WD9001HKHG 900GB 3.5″ 6Gbps 10,000 RPM WD X Enterprise Serial Attached SCSI Hard Disk Drive – Brand New
WD Xe Datacenter Hard Drives
Protect your investment by upgrading to the latest Enterprise performance storage technology from WD. WD Xe drives deliver 50% higher capacity, higher reliability and up to 67% lower power consumption versus 3.5-inch 15,000 RPM drives.
Product Benefits
- Ultra-Fast SAS Storage – WD Xe delivers 6 Gb/s transfer rates, sustained sequential data rates up to 204 MB/s, and a fast average read seek time of 3.6 ms.
- Industry’s Highest Reliability Rating – 2 million hours MTBF.
- Lower Power Consumption – The 3.5-inch SAS drive delivers up to 67% lower power versus 3.5-inch 15,000 RPM drives, which can result in substantially lower total cost of ownership (TCO) while increasing capacity and reliability.
- Dual Port, Full Duplex Connectivity – Offers higher reliability, performance and data availability by eliminating single points of failure, designed for high-availability mission-critical enterprise systems.
- 3.5-Inch Performance Adapter – WD Xe comes pre-mounted in a 3.5-inch performance adapter, providing easy installation into legacy 3.5-inch server and storage system slots, while optimizing the drive’s thermal management efficiency.
- Rotary Acceleration Feed Forward (RAFF™) – Optimizes operation and performance when the drives are used in vibration-prone, multi-drive chassis.
- NoTouch™ Ramp Load Technology – The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.
- Environmentally Conscious – In addition to being ROHS compliant, these drives are built with halogen reduced components.
