In addition to the features supported with the IBM SCSI-2 F/W PCI Adapter,
the IBM SCSI-2 F/W RAID adapter provides a RAID controller. Please
reference 1.6.5, “RAID Technology” on page 22 for a discussion on RAID.

1.6.4 Hard Disk Drives
Ultimately, the hard disk drive is the component that has the most effect on
subsystem performance. The following specs should be considered when
evaluating hard disks in order to optimize performance:
•
Average access time
•
Maximum transfer rate
•
On-board cache size
Average access time is one of the standard indicators of hard drive performance.
This is the amount of time required for the drive to deliver data after the
computer sends a read request. It is composed of two factors, the seek time and
the rotational delay. The seek time is the time necessary to position the heads
