Those are jumper settings. If you don't know what they are, you don't need to worry about them.

Those are jumper settings, similar to the IDE drives you mention, but for SATA specific options depending on the drive maker. For example, on this Western Digital support page for mobile drives, it shows two options:

• Reduced Power Spinup - RPS: Used by external hard disks to reduce spinup current and allows it to work over USB interface.
• Spread Spectrum Clocking - SSC: Used when your SATA controller doesn't support SSC by default.

If you didn't already know what it's for then you don't have to worry about it. It's basically never needed for most people and can be completely ignored.
