2.3 Timing
2.3.1 STANDBY IMMEDIATE Command
The Power-On-to-Ready time assumes a proper shutdown (power removal
preceded by STANDBY IMMEDIATE command. A STANDBY IMMEDIATE
before power down always performs a graceful shutdown and does not require
the use of the hold-up circuit. Note that SMART attribute 174 "Unexpected Power
Loss" records the number of non-graceful power cycle events.

2.4 Electrical Characteristics
2.4.1 Absolute Maximum Ratings
Values shown are stress ratings only. Functional operation outside normal
operating values is not implied. Extended exposure to absolute maximum ratings
may affect reliability.
