Connect Sata3 drive to multiple Sata2 ports?

[Kotu]

I was wondering, if it's possible to raid multiple hard drives to gain additional speed, does this mean there might be some way to do a similar thing but backwards?

eg. have a Sata3 drive connected to 2-3 Sata2 ports where the single drive is treated like a raid array

or even to connect a Sata3 drive to 4-5 Sata1 ports and keep is running at near full speed.

yes, but multiple sata ports could allow you to use a faster drive.

I wasn't intending it for Mechanical hard drives, I just wanted something which let me use a high speed cost effective SSD on older motherboards.

Instead of
4x 64GB SSD connected to 4x SATA 1.5 Gbit/s for a 6 Gbit/s raid array
I would use
1x 256GB SSD connected to 4x SATA 1.5 Gbit/s for a 6 Gbit/s drive
