Pipeline HD Mini Series SATA Product Manual, Rev. E 7
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 the noted val-
ues. 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.
2.8 Start/stop times
Time to ready Typical Max @ 25 ° C
Power-on to Ready (sec) 3.6 3.8
Standby to Ready (sec) 1.8 2
2.9 Power specifications
The drive receives DC power (+5V) through a native SATA power connector.
2.9.1 Power consumption
Power requirements for the drives are listed in the table on page 7. Typical power measurements are based on an
average of drives tested, under nominal conditions, 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 operation. Servo electronics are active. Seek mode power is measured based on three
random seek operations every 100 msecs. This mode is not typical.
• Read/write power and current
Read/write power is measured with the heads on track, based on three 63 sector read or write operations every
100 msecs.
• Idle mode power
Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a
random track location.
• Standby mode
Track-to-track (typical) 1
Average (typical) 14
Full-stroke (max) 30
Average latency 5.56
