Which of the following is eliminated when using SATA instead of PATA technology?

PATA drives required jumpers to be set to designate them as master, slave, or cable select when connecting multiple drives to a single IDE channel, which could be complex to configure. SATA, being a point-to-point connection, eliminates this master/slave configuration entirely, thus removing the need for jumper selections on the drives.

Both SATA and PATA drives require a power connector to supply electrical power for operation.

Both SATA and PATA drives utilize a data port connector to interface with the motherboard or controller, though the physical connectors are different.

Hard drive LEDs are typically part of the computer case or drive enclosure to indicate activity, not an inherent part of the drive technology itself that would be eliminated.
