Selecting The Right Lead Screw - Helix Linear Technologies
There is a ratio that directly shows the velocity of the screw based on input RPM (rotations per minute.) In high-speed applications a larger screw reduces the RPM, so the larger the screw you use, the lower the potential RPM.

Normally, ball screws are used to convert rotary motion into linear motion. Backdriving is the result of the load pushing axially on the screw or nut to create rotary motion. All ball screws, due to their high efficiency, will backdrive. The resulting torque is known as "backdriving torque" and is the torque required to hold a load in position.
