Seagate ST3750640SCE ユーザーズマニュアル

DB35.3 Series Serial ATA Product Manual, Rev. D

Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each 
10 reads) and 20 percent drive idle mode.

Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in 
a random track location.

During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/
write electronics are in power-down mode.

*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and 

power to operational levels.
