Rapid is disabled by default on the Pro. In fact I don't even think it's supported by anything but the EVO's.
Didnt know if it was out yet or not. None of my peoples have reported any problems with Pro models. Two friends have 2 in RAID 0 and another uses the small capacity version as boot drive. I dont have any issues with the EVO model and I have Magician on startup.
How many seconds does it last for? Maybe its indicative of another problem.
