Yes you can, they are backwards compatible. If you using a traditional HDD you probably wouldn't notice the difference and if you do it will be during sequential read/writes. If you are planning on using an SSD there is a pretty noticeable difference in 3 vs 6 gb/s read/write speeds.

yes you can... and it won't have close to 3gb write speed. hard drives don't push SATA I format let alone SATA II or III. You'd need a SSD to see that type of transfer speed.

actually SATA3.0 6gb/s is backward compatible so it's works fine with SATA2.0 3gb/s connector, In real time the speed provided or written in brochure does not occur it depend on various point so if you are using traditional harddisk you will hardly noticed anything or if you have plan to move to SSD's that you have worth noticing the read write or sequencial read write speed.

Absolutely.
Read and write speed should be below 200 MB/s for hard drive.

3/6gb refers to the buffer to sata interface speeds.
They are forward/backward compatible.
On a hard drive, the mechanical speeds are a fraction of that and are the controlling factor in performance.
Do not expect to see any difference in performance, either good or bad from the interface.

The only device where 3/6gb comes into play is with a ssd.
3gb will limit only the sequential transfer speeds to something like 250mb vs. 500mb.
Regardless, any ssd is 50x faster than a hard drive in random and 2x-3x faster in sequential depending on 3/6gb sata.
