My MSI X58 Platinum has an Esata port but I haven't had a chance to use it until I bought an external 1TB Toshiba with both esata & usb2.0 connections. Well, it took a while for me to get the esata to work with windows 7 by enable the bios. Anyhow, I was amazed how fast the Esata mode compares to USB mode. The pictures tell it all.
USB 2.0 MODE
eSATA Mode
