2.6Seek time

Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows:

•Track-to-track seek time is an average of all possible single-track seeks in both directions.

•Average seek time is a true statistical random average of at least 5,000 measurements of seeks between ran- dom tracks, less overhead.

Typical seek times (ms)

These drives are designed to consistently meet the seek times represented in this manual. Physical seeks, regardless of mode (such as track-to-track and average), are expected to meet the noted values.

Note However, due to the manner in which these drives are formatted, benchmark tests that include command overhead or measure logical seeks may produce results that vary from these specifications.

2.7 Start/stop times

Start/stop times @ 25°C

2000 and 1500GB models

 

 

Power-on to ready (max)

<17.0s

 

 

Standby to ready (max)

<17.0s

 

 

Ready to spindle stop (max)

10.0s

 

 

2.8Power specifications

The drive receives DC power (+5V or +12V) through a native SATA power connector. (Refer to Figure 3 ).

2.8.1 Power consumption

Power requirements for the drives are listed in Table 2 on page 15. Typical power measurements are based on an average of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature.
