Performance Factors
How well your new HP tape drive functions, particularly how fast it writes data
to tape, depends on a number of factors. Some of these factors are listed below.
Processor (CPU). The type and speed of your processor greatly affects the
speed at which your computer transfers data to and from the tape drive.
RAM. Your computer must have enough memory available to handle its
operating system, the backup software, and the data you are transferring to
and from tape. The system should not have to swap data to and from the
hard drive. Shut down other programs during a backup to ensure optimal
speed.
For optimal performance, run SCANDISK.EXE and DEFRAG.EXE on
your hard drive before using your tape drive for the first time (see your
operating manual for more information). In the future, run these executable
programs periodically. These programs improve access times to the hard
drive, which will help improve tape drive performance.
For HP Colorado tape drives only:
IDE Interface Type. To use the internal tape drive, your computer
requires an available connector on an IDE controller. Your computer may
have a "Single-FIFO" or "Dual-FIFO" IDE controller. If it is
"Single-FIFO," the tape drive will run 12 to 25 percent slower than with a
"Dual-FIFO" IDE controller.
Hard Drive. If you attach the HP Colorado tape drive to the same IDE
controller as a hard drive, the tape drive will run slower because it must
take turns using the data cable with the hard drive.
NOTE: Refer to your computer and motherboard manuals, or contact your
computer vendor, if you have any questions about your computer's configuration
or capabilities.
