From the Manufacturer WD Xe Datacenter Capacity HDD – High-density performance storage for demanding applications. WD Xe SAS 2.5 inch hard drives provide up to 900 GB of high performance storage suitable for both enterprise server and storage applications. The ultra-fast 6 Gb/s SAS interface enables optimum data reliability, availability, and scalability. Designed for environments where space is limited and low power consumption is needed, the WD Xe drives are an effective solution for online transaction processing (OLTP), database query, analytics, high-performance computing and multi-tenant server applications. Ultra-fast SAS Storage WD Xe delivers 6 Gb/s transfer rates, best-in-class maximum sequential data rate of 204 MB/s and outstanding random I/O performance. Low Power Consumption WD Xe SAS drives use less power resulting in, lower cooling costs and lower total cost of ownership (TCO) while increasing capacity and reliability. Industry's Highest Reliability Rating With a field-tested 2 million hour MTBF, this high performance drive is perfect for enterprise server and enterprise storage applications. Product Features Ultra-fast SAS storage - WD Xe delivers 6 Gb/s transfer rates, best-in-class maximum sequential data rate of 204 MB/s and outstanding random I/O performance. Lower your power consumption - WD Xe SAS hard drives provide up to 900 GB of high performance storage suitable for both enterprise server and storage applications. The ultra-fast 6 Gb/s SAS interface enables optimum data reliability, availability, and scalability. Designed for environments where space is limited and low power consumption is needed, the WD Xe drives are an effective solution for online transaction processing (OLTP), database query, analytics, high-performance computing and multi-tenant server applications. 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. (HKHG models only) Dual processor - Twice the processing power to maximize performance. 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. Dual actuator technology -A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy. StableTrac - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations. (2 TB and above) Multi-axis shock sensor - Automatically detects the subtlest shock events and compensates to protect the data. Vibration Protection - Enhanced RAFF technology includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration in real time. The result is a significant performance improvement in high vibration environments over the previous generation of drives. RAID-specific, time-limited error recovery (TLER) - Prevents drive fallout caused by the extended hard drive error-recovery processes common to desktop drives. Thermal extended burn-in test - Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation. Dynamic fly height technology - Each read-write head's fly height is adjusted in real time for optimum reliability. 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 responsible - In addition to being RoHS compliant, these drives are built with halogen reduced components. The WD advantage - WD puts our datacenter products through extensive Functional Integrity Testing (F.I.T) prior to any product launch. This testing ensures our products consistently meet the high quality and reliability standards of the WD brand. Following a FIT test the Enterprise System Group (ESG) testing validates interoperability with HBAs, operating systems and drivers to ensure an even greater level of quality, reliability and peace of mind. WD also has a detailed Knowledge Base with helpful articles and software utilities. Our customer support lines have longer operational hours to ensure you get the help you need when you need it. Our toll-free customer support lines are here to help or you can access our WD Support site for additional details. Self Encrypting Drive (SED) Option - SATA Drive: Optional secure model for encrypting drives – Utilizing an AES 256 bit encryption engine for Crypto erase capability, WD supports both industry standard commands of the Sa
