During continuous Seek, Read, or Write commands, an algorithm in the code will add latency as required to keep
the VCM motor from overheating. Seek performance will be impacted under this condition.

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and
one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As
used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte
per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second.
Effective maximum SATA 3 Gb/s transfer rate calculated according to the Serial ATA specification published by
the SATA-IO organization as of the date of this specification sheet. Visit www.sata-io.org for details.

Defined as the time from power-on to the setting of Drive Ready and Seek Complete including calibration.
4
Defined as the time from power-on to when the full spindle rotational speed is reached.
