Barracuda 4LP Product Manual, Rev. D 5 3.0 General description Barracuda 4LP drives combine magnetoresistive (MR) heads, partial response/maximum likelihood (PRML) read channel electronics, embedded servo technology, and a SCSI-3 (Fast-20) interface to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. Fast-20 (also known as Ultra SCSI) is a negotiated transfer rate. This transfer rate will occur only if your host adapter also supports Fast-20 data transfer rates. This drive also operates at SCSI-1 and SCSI-2 data transfer rates for backward compatibility with non-Fast-20 capable SCSI host adapters. Table 1 lists the features that differentiate the various Barracuda 4LP SCSI-3 Fast-20 (Ultra SCSI) models. Table 1: Drive model number vs. differentiating features Model number Number of Heads I/O circuit type Number of I/O connector pins Number of I/O data bus bits ST34371N 10 single-ended 50 8 ST34371W 10 single-ended 68 16 ST34371WD 10 differential 68 16 ST34371WC 10 single-ended 80 16 ST34371DC 10 differential 80 16 ST32171N 5 single-ended 50 8 ST32171W 5 single-ended 68 16 ST32171WD 5 differential 68 16 ST32171WC 5 single-ended 80 16 ST32171DC 5 differential 80 16 ST34571N 10 single-ended 50 8 ST34571W 10 single-ended 68 16 ST34571WD 10 differential 68 16 ST34571WC 10 single-ended 80 16 ST34571DC 10 differential 80 16 ST32271N 5 single-ended 50 8 ST32271W 5 single-ended 68 16 ST32271WD 5 differential 68 16 ST32271WC 5 single-ended 80 16 ST32271DC 5 differential 80 16 The drive records and recovers data on 3.5-inch (86 mm) non-removeable discs. The drive supports the Small Computer System Interface (SCSI) as described in the ANSI SCSI-2 interface specifications to the extent described in this manual (volume 1), which defines the product performance characteristics of the Barracuda 4LP family of drives, and the SCSI Interface Product Manual (volume 2), part number 77738479, which describes the general interface characteristics of this and other families of Seagate SCSI drives.
