KEY ADVANTAGES
BARRACUDA 36ES2
36.9-Gbyte and 18.4-G byte capacities designed for market
sweet spots
Ultra SCSI (8 bit) 20-Mbytes
Compatible with Ultra2 and all other 160-Mbyte SCSI implementations
Entry-level SCSI providing the right balance between cost and
performance. Designed with the Seagate Advanced Multidrive
System
(SAMS) a set of designs that reduces the effects of
rotational vibration generated from multiple drives operating
simultaneously in a cabinet, keeping performance on track while
competitor drive performance suffers
Entry-level SCSI incorporates 2-Mbyte cache for extra performance
Most advanced technology on the market. Industry
leading components create high Areal Density, and high reliability
3D Defense System: No one does more to protect your drive
3D Data Defense: ECC, Safe Sparing, Continuous Background
Defect Scanning
3D Diagnostics: Enhanced S.M.A.R.T. preempts errors. Web-based tools and
Seatools diagnostic software helps customers identify problem sources
Lowest acoustics ever offered on a SCSI drive!
Temperature Sensor warns host when the temperature exceeds limits
The highest shock rating for any SCSI drive!
G-Force Protection increases drive ruggedness and reliability
Experience with the seventh-generation Seagate Barracuda
family of products ensures low power requirements.
