The slimline connector is defined in SATA 2.6 specification and intended for smaller form-factors such as notebook optical drives. Pin 8 of the slimline power connector, denoting device presence, is shorter than the others to allow hot-swapping. The slimline signal connector is identical and compatible with the standard version, while the power connector is reduced to six pins so it supplies only +5 V, and not +12 V or +3.3 V.
