I use 3 Hard drives (HDD) for my Data storage. They are connected through USB 2.0, eSATA and SATA II. I also have a New Mobo that has SATA II and III ports. My issue is that I am wondering whether the USB 2.0 is good for my 3 hardisks or should I change it and use the Mobo although I am contented with the speed that they have. I am also considering using a PCI SATA 11 card but I think it has some compatibility issues. I need anyone’s advice on this.
What kind of port to use for 3 hard drives

You haven’t mentioned about your Motherboard bus speed. But I don’t need that because it’s very simple that if you connect directly to Motherboard then you would find the highest speed.PCI SATA 11 is not a bad option either. But you haven’t mention which you would use and in which operating system if you using windows 7 then type will run faster and if you using XP then another type will run faster. But at first you have to what type of operating system to use. But steel I would say as a technician that Motherboard option is best one and usb option is the worst one.

If you are not experiencing any problem with the speed you are getting from the USB 2.0 port then there’s no need to change the interface you are using. Whatever type of USB port you use on your computer, it will still go down to the maximum speed that your motherboard bus can offer.
If your motherboard supports USB 2.0 by default, adding a USB 3.0 port adapter will not change the maximum output speed of the bus. It will still go down to the maximum possible speed that a USB 2.0 bus can support.
Adding a USB 3.0 port adapter will only allow you to use USB 3.0 devices but it will not increase the maximum data transfer to what a standard USB 3.0 supports. In your case, even if you add a PCI SATA 11 expansion card, the data transfer speed will still go down to the bus speed supported by your motherboard.
