slim-line design, which measures 8 by
5.75 by 0.75 inches, fits into any avail-
able 5.25-inch bay in most modular PCs
without any customization to system

drives mount exactly like a CD-ROM
unit, installation is actually easier than
a traditional 3.5-inch drive, since no
brackets or mounting rails are required.

particularly beneficial for users who are
upgrading their system through the
addition of a second hard disk drive.
