Everything You Need To Know About SATA Cable

SATA Cable

SATA aka Serial Advanced Technology Attachment is a tool used to connecting optical drives and hard drives to the motherboard. Short for SerialATA, SATA 1.0 was released in August 2001. SATA is a good replacement of Parallel ATA (PATA) used in IBM compatible computers.  Serial ATA (SATA) devices can transmit data from and to the rest of computer much faster than the PATA devices.

SATA is capable of delivering 1.5 GBPS speed to each of the drives within a single disk array. It offers a small and thin cable solution and has the benefit of being backward compatible with ATA and ATAPI devices. SATA cables make it much easier in cable routing and provide better airflow in the computer when compared to PATA ribbon cable drives.

Features of SATA Cables and Connectors:

The operating system or device using the SATA Cable must support the hot swapping because SATA drive supports it. These cables are 15-pin (for power supply connection) and 7-pin (for the data transmission) long with thin and flat endings.

One end of the SATA Cable connects to the storage devices like SATA hard drive and the other end connects to the motherboard SATA drive. The external drives are supported by SATA only through External SATA which is also known as eSATA.

SATA cables can be as long as 1 meter. SATA transfer speeds are much faster than PATA. In PATA drives the maximum speed can be only 133MB/s while in SATA devices the transfer speed ranges from 187.5MB/s to 1969 MB/s.

SATA Converter Cables:

There are various adapter cables available in the market that can help you to convert SATA to other connection types or a remote cable type to SATA cable. For example, in case you need to use your SATA hard drive through a USB to backup files, browse data or wipe data then you can use SATA to USB adapter.


eSATA or External SATA is the device which assists SATA to support external drives. The eSATA supports a disk driving technology named as Self Monitoring Analysis and Reporting Technology (SMART). eSATA supports quicker transfer speed with FireWire and USB and is hot-swappable.

There are also several disadvantages of eSATA. All the drives need an external power source because eSATA doesn’t distribute power through USB. Along with

this, the length of eSATA is maximum 2 meters which can only transmit data. eSATA cables cannot transfer power, eSATA also needs a power source.

The USB ports are connected with eSATA at one opening which allows external drives like monitor, network cable to connect. The other end of the SATA connection is done with the motherboard of the computer.

SATA differentiates the master-slave relationship between parallel hard drives with the connecting motherboard to each driver using its own SATA adapters. PATA is gradually being fade and obsolete. It is completely replaced with SATA which provides a lot of benefits for your computer and data transfer.
