Its 3 seconds and only active for internal uSD. You need really new 1.5 firmware to have this delay. If you are running on external SD there is at least one 8 gig card with a flash controller (which could be in multiple different cards) that will become completely unusable if you power it off less than 2 seconds or so from the last write. I recommend you do hard power offs little as possible. Suspend/resume also should be disabled. -- Richard A.
