Explanation

Serial ATA (SATA) is a computer drive interface that has data transfer rate from 150 to 300 MBps. SATA 150 and SATA 300 have data transfer rates of 150 MBps and 300 MBps, It is a new serial bus implementation of an ATA style interface. The SATA standard defines a data cable using seven conductors and 8 mm wide wafer connectors on each end. SATA cables can be up to 1 meter long, whereas Parallel ATA (PATA) ribbon cable has either 40-conductor or 80-conductor wires and is limited to 46 cm length. SATA also offers new features such as hot-swapping and native command queuing. SATA standard specifies a new type of power connectors such as data cable. A power connector's wider 15-pin shape prevents accidental misidentification and forced insertion of the wrong connector type. SATA power connector pins supply 3.3V, 5V, and 12V. Adaptors are available in the market to convert a 4-pin Molex connector to a SATA power connector. However, since 4-pin Molex connectors do not provide 3.3V power, these adaptors provide only 5 V and 12 V power and leave the 3.3 V lines disconnected. This makes impossible the use of such adaptors with disk drives that require 3.3 V power. Many drive manufacturers leave the 3.3V power lines unused. However, without 3.3 V power, a SATA device may not be able to implement
