Well here are the hard drives im looking at. I have a 60gb laptop hd running at 5400 rpms. Dont have any extra sata cables or know too much about sata. Could someone explain the difference between sata 1, 2 and 3 besides the speed differances. Like compatability etc. Here are the three hd's im looking at budget of 80 bucks so any reccomendations are welcome. Either from Newegg or Tigerdirect idc which.

What one would you reccomend? And could you include a link to whatever cable i need if you say a bare drive. My mobo is a http://www.newegg.com/Product/Product.aspx?Item=N82E168... .
Also what would be better keep os installed on laptop Hd or putting it on the hard drive i buy? Run Ubuntu and XP if it has any bearing, will be upgrading to 7 in a while. Any notes are helpful.
Thanks for all of your reccomendations.

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.

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.
