2.7 Seek 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 rand om average of at least 5,000 measure ments of seeks between random tracks, less overhead.

*Typical seek times (msec) Read Write

Track-to-track <1.0 <1.2 Average 8.5 9.5 Average latency: 4.16 4.16

*Measured in performance mode . Note. 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 or exceed the noted values. 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.

Barracuda 7200.7 Product Manual, Rev. N 7

2.9 Power specifications

The drive receives DC power (+5V or +12V) through a four-pin standard drive power connector.

2.9.1 Power consumption

Power requirements for the drives are listed in the table on page 8. Typical power measurements are based on an average of drives tested, under nomi nal conditions, using 5.0 V and 12.0V input vo ltage at 25°C ambient temperature.

• Spinup power

Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.

• Seek mode

During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does not execute a read or write operatio n. Serv o electr onics ar e active. S eek mode power repres ents the worstcase power consump tion, using only random se eks with read or write laten cy time. This mode is not typic al and is provided for worst-case information.

• Read/write power and current

Read/write power is mea sured with the he ads on track, base d on a 16-secto r write followed by a 32-msec delay, then a 16-sector read followed by a 32-msec delay.

• Operating power and current

Operating power is mea sure d using 40 percent random s eek s, 40 p erce nt r ead /write mod e ( 1 wri te fo r e ach 10 reads) and 20 percent drive idle mode.

• Idle mode power

Idle mode power is measur ed wi th th e driv e up to s pee d, wi th ser vo ele ctron ics act ive and with the heads in a random track location.

• Standby mode

During Standby mode, the driv e accepts commands, but the dr ive is not spinning, and the ser vo and read/ write electronics are in power-down mode.
