Does anyone know if the HDD is a flash RAM system or an actual spinning drive? I would imagine a flash RAM or NAND system would be appropriate for all of the off-roading expected, but I just can't find any details. If it's a spinning drive, I would think it would be best to play music from the USB or streaming Bluetooth from the phone.

 

IIRC it's an actual hard drive. I know on my 430n you can here it power down after the 45 secs

 

Yes, it's an actual hard drive.
