Carrying on the heritage of WD Caviar SE hard drives as industry-leading performers, Western Digital offers WD Caviar SE Serial ATA (SATA) hard drives which feature capacities as large as 250 GB and an 8 MB buffer, to fill acute demand in market segments such as high-end PC, workstation, and entry-level servers. Designers of enterprise storage systems and servers are increasingly using desktop-class, large-capacity SATA hard drives because of the advantages provided by the SATA interface. Benefits include a data transfer rate of 150 MB/s and improved cabling that enables greater system design flexibility.

Product Benefits

!8 MB cache – 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 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.

!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.

Note: Western Digital's Serial ATA cable with SecureConnect is recommended for use with all Western Digital Serial ATA hard drives.

!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 – allows swapping of hard drives without having to power down the system or reboot; promotes system design flexibility, data availability, and serviceability.
