No hard drive can reach SATA III or even SATA II speeds....so unless you have em in RAID, higher SATA interface numbers won't help you with large data file transfers.....that doesn't mean however that there is no advantage .... transfers from cache can easily exceed SATA II speeds so if it's a lotta little files being saved back and forth, you will see an impact there.

Even RAID won't increase the speed of the individual drives, so which generation of SATA you use still won't affect the overall speed you can achieve. The only way SATA would impact RAID speed is if a hardware RAID controller used SATA as an interconnect to the system - but most of them use PCIe.
Well is sata 1 2 and 3 compatible? and anybody with a HD reccomendation and with the what hd to install to?
Yes, they're compatible. Just plug any SATA drive into any SATA controller and you're off to the races. There are occasional drive/controller combinations that have a problem negotiating the correct SATA protocol, so drives usually have a jumper that lets you force it into a slower SATA connection speed. But again, this won't really slow it down since the data can't be transferred to or from the rotating platter that quickly anyway.
I pretty much treat drives as commodity items and buy them on the basis of price and performance class.
