Seagate Cheetah ST318452LC X15 36LP 15K.2 18GB 15K U320 80pin SCA-2 SCSI Hard Drive - Brand New

ALT. PN: 9T4006-001

Cheetah X15 36LP drives combine giant magnetoresistive (GMR) heads, partial response/maximum likelihood (PRML) read channel electronics, embedded servo technology, and a wide Ultra160 SCSI interface (on ST336752 and ST318452 models) or a wide Ultra320 SCSI interface (on ST336732 and ST318432 models) to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers.

Ultra160 and Ultra320 SCSI use negotiated transfer rates. These transfer rates will occur only if your host adapter supports these data transfer rates and is compatible with the required hardware requirements of the I/O circuit type. This drive also operates at SCSI-1 and SCSI-2 data transfer rates for backward compatibility with non-Ultra/Ultra2/Ultra160/Ultra320 SCSI host adapters.

Compatibility:

This drive is compatible with any server that accepts 3.5" x 1" (LFF) SCSI drives.
