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.

     Note: LW and LC drives do not have internal terminators or
           any other way of adding internal terminators to the
           drive; use external active termination if required.
           Use active (ANSI SCSI-2 Alternative 2) terminators
           when terminating the bus.  Use active negation
           terminators when terminating a SCSI Ultra2 bus
           operating in Low Voltage Differential (LVD) mode.
