Disk Drives 

HP C24xx Series 

The HP C2400 family of disk drives are supported with the small computer
system interface (SCSI) on the Series 9x7LX and 9x7 systems.  These disks
combine compact size with high-density data storage to provide an
inexpensive storage system for the 900 Series low-end and midrange
systems.

The HP C2204A provides 1.34 Gbytes of formatted data storage on sixteen 5
1/4-inch platters and is an ideal product for high-end mass storage.
HP's complete range of disk drive products offer low-cost-per-megabyte
storage for all HP 3000 systems.

It is possible to rackmount HP disk drives.  The Series 6000
multi-mechanism package allows up to three C24xx disk drives to be
stacked in a single cabinet.  The C2204A disk drive can also be stacked
in a standalone cabinet.  Modular design offers great flexibility in
rackmount and cabinet configurations to help you optimize the use of
floor space.  Low power consumption and a wide tolerance for ambient
conditions make the disk drives suitable for installation in a variety of
environments, including the factory floor, the data center, and the
typical business environment.

A sophisticated dual servo system in each drive provides fast head
positioning with the precise accuracy required by high track densities.
Variable-length frequency modulation is used to take full advantage of
the high bit density available with HP-designed and HP-manufactured
thin-film media.
