Yes, I found the little arrows! Thank you! As for the esata - yes, it does look like it will fit into the regular sata ports on the mobo. I have both Sata II and Sata III. I assume plug it into sata II ?
The best controller will be the one with "hot plug" support. It's a BIOS setting. Try both and see which one allows the drive connected to it to use the "safely remove hardware" button.
