HP 3R-A6765-AA ProLiant/StorageWorks HDD

The HP 3R-A6765-AA is a 300GB Ultra320 SCSI hard disk drive built for HP ProLiant and StorageWorks server and storage platforms. Ultra320 SCSI was HP’s mainstream high-reliability server drive interface through the mid-to-late 2000s, offering a 320MB/s bus transfer rate and the hot-plug, dual-port capability needed for enterprise RAID arrays and clustered storage. At 300GB, this drive sits toward the higher-capacity end of the Ultra320 generation, typically supplied in HP’s standard hot-swap tray for direct installation into a compatible drive bay without powering down the host system. It’s a common like-for-like replacement or capacity-expansion part for engineers maintaining older HP server and storage deployments still running Ultra320-based arrays. Tech-Star (UK-based, shipped worldwide) supplies tested server hard drives. Enquire to confirm exact bay/carrier compatibility before ordering.
