It's also important whether the SATA controller is passed through USB or properly connected. Some boards have abysmal SATA performance because of that.
By rule SATA in Board-DB means "native SATA" as USB-SATA sucks. Some boards with USB3-SATA are listed with a notice that SATA isn't native, but USB2-SATA is definitely banned from being referred to as "SATA".
