The Cheetah 10K.6 is Seagate's sixth-generation 10K RPM high performance, high capacity disc drive. With the fastest interfaces, the highest reliability and the most mature product design, the Cheetah 10K.6 enables the lowest ownership cost. In data intensive environments, increasing the capacity per disc drive lowers ownership costs by deploying fewer systems that use less cubic feet of space requiring less infrastructure such as cabinets, HBAs and less wattage of power.

     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.
