In these cases please connect only one of the power connectors to the power supply. There are SATA hard drives that feature the IDE and SATA power connectors for flexibility. Thus you may only find a SATA power and SATA data connector available at the back of your SATA drive. Since one SATA cable will only connect to one SATA hard drive, there is no jumper for slave/master mode selection on the back panel of a SATA hard drive (some SATA 3.0 Gbps compliant hard drives may feature a jumper for SATA 3.0 Gbps / SATA 1.5 Gbps mode selection). If you connect two hard drives (or a hard drive and another IDE device) on a single IDE cable, one of them should be set as master and the other as slave.

On the back panel of an IDE (PATA) drive you will find, besides the power and data connectors, a set of jumpers which are used to set the hard drive to work in either master or slave mode. The 4-pin molex to SATA converter cable is the other option.Ĥ-pin molex to SATA power converter cable Since the SATA power connector is unavailable on many power supplies, some SATA hard drives provide both the 4-pin molex and SATA power connectors for flexibility. The standard SATA power connector is a thinner but features more pins. IDE hard drives receive power through a 4-pin molex connector, which typically provided in abundant numbers by most power supplies. A SATA cable is only allowed to connect to one SATA storage device. This is especially pronounced when there are 3~4 hard drives installed. The slim design of the SATA cable promotes better airflow inside the case for improved temperature management. The SATA cable features only seven pins for an easier connection. An IDE cable can be used to connect up to 2 IDE devices if there are three connectors present one which is used to connect to the IDE port on the motherboard and other two the IDE ports on the storage devices.Ĭompared to the IDE cable, the SATA cable is much thinner and simpler. The traditional IDE data cable consists of two or three 40-pin connectors, as well as a wide cable with 40- or 80-conductor inside (the IDE devices utilizing ATA 66, ATA 100 or ATA 133 interface must use the 80-conductor IDE cable). The newer SATA standard brings new features and improved I/O throughput compared to IDE, as well as other differences: There are currently two types of internal hard drive connection interface used in desktop PCs: SATA (serial ATA) and the PATA (parallel ATA, also known as IDE).
