In the BIOS check something called HHD delay & make sure it's set to zero seconds.
PS Did you install the Intel RST?? If not, then don't for now
HDD delay is 0, no RST.....
Hbomb, this behavior could be related to compatibility between the motherboard and the SSD.
This board is a few years old (2008) and it only has SATA 2 (3.0 Gb/s). The hard drive you are using requires SATA 3 (6.0 Gb/s).
Have you checked whether you have the latest firmware on the SSD?
When SSDs work in compatibility mode "i.e. reverting from SATA 3 to SATA 2" it does have certain compatibility issues but none warrant a 30secs delay "such an issue is not among the documented ones".
IS BIOS ver. .118 the latest??
