Resume from S4 Hibernation
Hibernation or S4 is part of the Advanced Configuration and Power Interface specification. In our custom "Resume from S4" testing, we allow the drive to enter hibernation for a period of ten minutes, from there we use our trusted stopwatch and time how long it take for the drive to resume to working desktop environment.
To meet Gen. 2 Ultrabook Certifications a drive must resume within seven seconds.
Obviously I know this drive isn't meant for Ultrabook laptops, mainly because of its Z-Height of 9.5mm. We must however test all drives equally.
Above we found the HGST to be rather impressive with a resume from S4 time of just over 11 seconds.
