Barracuda 18FC Product Manual, Rev. B 7
3.4 Reliability
• 1,000,000 hour MTBF
• LSI circuitry
• Balanced low mass rotary voice coil actuator
• Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.)
• Dithering
3.5 Unformatted and formatted capacities
Standard OEM models are formatted to 512 bytes per block. You can order other capacities by requesting a dif-
ferent sparing scheme and logical block size.
The standard OEM model capacities are listed below.
Users having the necessary equipment may modify the data block size before issuing a format command and
obtain different formatted capacities than those listed. The
ST118273FC
drives use a zone sparing scheme. The
drives are divided into frequency zones with a variable number of spares in each zone.
3.6 Factory-installed accessories
OEM standard drives are shipped with the
Barracuda 18FC Installation Guide
(part number 77767525).
3.7 Factory-installed options
You may order the following items which are incorporated at the manufacturing facility during production or
packaged before shipping:
• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection
against transit damage. Units shipped individually require additional protection as provided by the single unit
shipping pack. Users planning single unit distribution should specify this option.
3.8 User-installed accessories
The following accessories are available. All kits may be installed in the field.
• Evaluation kit, part number 73473641.
This kit provides an adapter card (“T-card”) to allow cable connections for two FC ports and DC power. Two
twin axial cables, 6 feet in length, are included for the input and output connections to the FC interface.
