General Description and Specifications
2-2Quantum Atlas 10K II 160/m SCSI Hard Disk Drives
• 4.7 ms second average random seek time (read) and 7.9 ms average access-to-
data time for the 1.0-inch drives; 5.2 ms second average random seek time (read)
and 8.4 ms average access-to-data time for the 1.6-inch versions of the drive.
• Embedded servo system for exceptional head positioning accuracy and long life
• “Zero latency” reads and writes reduce data access time
• Full SCSI–3 compliance 1 (compatible with SCSI-2 and SCSI–1)
• Advanced Ultra 160/m-LVD, Ultra2-LVD and Ultra SE Multimode SCSI with
68-pin wide connector or 80-pin SCA-2 connector
• Superior data integrity:
› 352-bit Reed-Solomon quad-burst ECC provides fast on-the-fly correction for
small errors and robust software-based correction for larger errors
› EDC internal protection from SCSI bus to media

2.4 HARDWARE REQUIREMENTS
The Quantum Atlas 10K II Ultra 160/m SCSI hard disk drives are completely
compatible with host computers and controllers that provide a 68-pin Wide or 80-pin
SCA-2 interface. A 50-pin to 68-pin adapter is required to use the 68-pin Wide drive
in a 50-pin cabling configuration.
1The drives are in compliance with the SCSI-3 draft proposed ANSI standards as
they exist at the time of product release; SCSI-3 features may not be enabled on
drives when shipped.
