Take 45s to boot a brand new Mac Pro

Question

Hi Mac Pro folks
I just got a brand new Mac Pro running Mountain Lion. It came with a 512MB SSD as the boot disk and a 2TB disk as the second drive. What I got confused is: after powering it on, the Mac Pro takes average 45s to boot to the white screen with an Apple logo.
This is actually the second Mac Pro, the previous one having the same configuration took 30 seconds to boot. As the previous one's second drive got clicking sound from the first day, Apple replaced the whole machine. Now the clicking sound has gone, but the second Mac Pro takes an even longer time to boot from SSD.
Is it normal? Has anyone ever experienced the same thing?
Thanks for any comments.
Regards,
B

It should be Apple genuine SSD, as the 512 MB SSD comes with the new Mac Pro. Please see below its information retreived from System Report. TRIM Support is enabled.

This is a Mac Pro 5,1 so I would expect it should take less than 10 seconds to boot.
Moreover, the SSD is the only startup device under Startup Disk.
It seems the only PCI card is the ATI Radeon HD 5770 that comes with the system.

Probably trying to use a 512MB boot device?
No it should take 10 seconds. That is what my SSD on Mac Pro 1,1.
PCIe cards can affect booting, especially if you boot from one.
3rd party SSD or not? \
firmware is current?
SSD is set to default startup disk control panel?
You've done ML Recovery and checked the SSD twice: the top of the drive to check partitions, the user volume to check the system directory.
If it is 3rd party what make?
Does it show TRIM is enabled in SATA entry in System Profile?
What else is installed.
Does not sound normal to me to replace anything except the hard drive for clicking, and then to just zero the drive.
I would never pay for disk drive from Apple when there are better prices and as good devices.
