Re: what is sata e1?
the E1 sata port is probably a special function port for your motherboard. Get your motherboard manual out and read up on what it says you can do with that port. or post up your motherboard model number and I'll take a look for you.
The ESATA port at the top is a special kind of sata port. Basically it allows for longer SATA cables to be attached to it (e.g. for external drives with eSATA connectors)
Normal SATA connectors don't have enough power to use very long cables.
