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 designed for high-end PC, workstation, and entry-level servers.
Features:
8 MB cache - fast data transfer from a cache four times larger than the industry-standard 2 MB size.
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.
Backplane compatibility - promotes expandability and flexibility in system architecture.
