sata #
power and data plug are seperate connectors with a split between the two.
sas #
sff-8482 (sff-8680) - eia-966 (aka: sas connector) #
- sff-8482: serial attachment 2x unshielded connector
- sff-8680: serial attachment 12gb/s 2x unshielded connector
your basic sas disk connector. both power and data are in a single connector with a notch where the split is between sata connectors. this will prevent you from using sata power and/or data on sas disks. the top side of the notch also has extra pins.

- sff-8630: serial attachment 12gb/s 4x unshielded connector
like sff-8482 but with more pins to support multilink, should compatible i think.

looks like sff-8482 but with even more pins to support pci-e.
