<Solved>SSD drives sata3 in sata2 holes

[gezza]

I have just install PCLOS 2012.02 on a sata3 SDD drive on a sata2 mother board and find it is only marginally faster than a sata2 drive and is certainly very much slower than a sata3 drive.
When first installed it booted the system in 18secs. which I thought was fast. When I added a second sata3 drive on the same mother board the speed dropped to 35 secs. Now I cannot get 18 seconds back even after removing the second drive.
Indeed, creating a live cd is taking forever, it is currently a 36% after 1hr and 30 mins.
On a sata3 system with a sata2 boot disk, the system completed the live cd in 30 mins.
The SDD is a Corsair Force 3 sata3 series 60GB.
Do sata3 drives run more slowly than sata2 in sata2 slots?
Does anyone have any comparison systems that could be verified.
I thought SSD's were the bees knees,but it looks as though I am wrong.
Your thoughts on this matter gratefully received.

Do I need to tweak my operating system to get my Corsair SSD drive to run at optimal performance?

No settings within your operating system need to be adjusted for a Corsair SSD drive to run at optimal performance.

What settings do I need to adjust in my system BIOS for optimal SSD performance?

Enabling AHCI storage mode in your BIOS is the only setting we recommend adjusting for optimal SSD performance.

What motherboard are you using gezza?

Hi, darkages
Asus M3N78-EMH HDMI Motherboard.
2GB ram, 1st drive Corsair SDD 60G, 2nd. drive Hitachi 2TB.
Nvidia 8400GS
AMD Phenom 8450 3 core.
I had read the info from the forum and did as they said.
I have now re-installed 2012.02 on the system and now it boots in 20secs.
So I think the info I got was not correct.
But you are correct, as my re-install confirms.
Mant thanks for your reply.
