É SATA 7 ou 15 pinos?

The SATA standard defines data cable connector consisting of:

• 40 pins

• 34 pins

• 15 pins

• 7 pins

I chose 15 pins. It was wrong. The correct answer was 7.

• Um cabo SATA data tem 7 pinos.

• Um cabo SATA power tem 15 pinos.

Conector de dados

The SATA standard defines a data cable with seven conductors (3 grounds and 4 active data lines in two pairs) and 8 mm wide wafer connectors on each end.

Conectores de energia

SATA specifies a different power connector than the decades-old four-pin Molex connector used on Parallel ATA (PATA) devices. It is a wafer-type connector, like the SATA data connector, but much wider (15 pins versus seven) to avoid confusion between the two. Some early SATA drives included the old 4-pin Molex power connector together with the new 15-pin connector, but most SATA drives now have only the latter.
