Seagate Barracuda 18LP 9GB 7.2K Ultra2 68pin SCSI Hard Drive ST39175LW - Brand New OEM
Alt MPN: 9L6002-010
Barracuda 18LP drives combine magnetoresistive (MR) heads, partial response/maximum likelihood (PRML) read channel electronics, embedded servo technology, and a SCSI-3 (Fast-20 and Fast-40) interface to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers.
Fast-20 and Fast-40 (also known as Ultra-1 SCSI and Ultra-2 SCSI, respectively) are negotiated transfer rates. These transfer rates will occur only if your host adapter also supports these data transfer rates. This drive also operates at SCSI-1 and SCSI-2 data transfer rates for backward compatibility with non-Fast-20/Fast-40 capable SCSI host adapters.
