Description:
Description :
Western Digital offers WD Caviar SE Serial ATA (SATA) hard drives with features and capacities that are ideal for next-generation computers and low-end enterprise storage. Users benefit from a data transfer rate performance roadmap that begins with 150 MB/s and extends to 600 MB/s, as well as improved cabling that enables greater system design flexibility. Designers of enterprise storage systems and servers are increasingly using desktop-class, large-capacity SATA hard drives because of the advantages that the SATA interface provides.
Features and Benefits :
Bare Drive
8 MB cache buffer - fast data transfer from a cache four times larger than the industry-standard 2 MB size.
7200 RPM - high-performance rotational speed for high-capacity hard drives.
Data Lifeguard Tool - 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 management diagnostics and repair simple and worry-free.
SecureConnect - provides a 500 percent stronger cable-to-drive connection than first-generation SATA hard drives and cables; ensures backward compatibility with legacy SATA cables and backplanes.
FlexPower - connector technology that accepts power from both industry-standard and new SATA power supplies.
Point-to-point bus configuration - utilizes the full bandwidth of each drive interface in a networked environment.
Hot plug support - ability to swap out a hard drive without having to power down the system or reboot promotes system design flexibility, data availability, and serviceability.
Backplane compatibility - promotes expandability and flexibility in system architecture.
Longer, narrower cable - prevents incorrect mating and bent pins, providing greater reliability and reduced service calls.
