Feature / Function

Benefits

Reliability

• IDRC technology

• RRO fields

• End-to-end data protection (ANSI)

• Improves signal processing for more robust data integrity

• Improves handling of repeatable run out to lower risk of data squeeze and write inhibit rate

• Enhances error detection for optimal data integrity

Security

Optional SED models

Encrypts data, providing security and easy redeployment

1 One MB is equal to on million bytes, one GB is equal

to one billion bytes and one TB equals 1,000GB (one

trillion bytes) when referring to hard drive capacity.

Accessible capacity will vary from the stated capacity

due to formatting and partitioning of the hard drive, the

computer’s operating system, and other factors.

2 MTBF and AFR targets are based on a sample

population and are estimated by statistical

measurements and acceleration algorithms under

median operating conditions. MTBF and AFR ratings

do not predict an individual drive’s reliability and do not

constitute a warranty.

3 Portion of buffer capacity used for drive firmware

4 1MB/s is equal to 1,000,000 Bytes/s; Sustained Transfer
