SATA Ports: Everything Explained About SATA ports

Are you also here to know about SATA ports? Here’s a fast, easy-to-understand overview aimed at clearing up any of your misunderstandings.

This article will give you a basic grasp of SATA ports, what they are, how they look, and how they work.

What Are SATA Ports?

Hard drives are connected to motherboards using SATA ports, which are sometimes known as connectors.

Two SATA ports are available on the motherboard. They use a SATA data cable to transfer data between the motherboard and the disc.

A motherboard typically has 4 to 8 SATA ports, although the size and chipset differ from one model to the next.

SATA also allows you to do swapping, which means you can plug an SSD into and out of SATA ports without turning the computer off.

This makes it an outstanding connector for external hard drives, which is attained using a SATA to USB converter. It is being used in the 2.5″ external USB hard drives.

Anyone who has used a computer in the last ten to fifteen years is likely to have noticed a Serial ATA (SATA) port on the motherboard. On computer motherboards, it’s a seven-pin L-shaped connector.

How Does a SATA Port Work?

Every computer has a network of various channels that are known as buses which it utilizes to transfer and receive data.

As a result, SATA, which is a newer version of it, functions similarly and is used to link the motherboard to various large-capacity storage devices.

SATA cables transmit data and information in the form of bits, and a newer generation of SATA SSDs (now SATA III) has faster data transmission speeds. A standard SATA cable has four conductors.

There are two types of SATA connectors: the data connector, which has seven pins and resembles a little “L,” and the power connector, which has four pins.

There are 15 pins on the other power connector. It likewise has the appearance of a data connector, however, it is taller.

The SATA ports on almost every motherboard are also titled with the fastest speed that they provide. The SATA 3 port provides 6Gb/s speed and will be branded as such on the motherboard, whereas the SATA 2 and SATA ports will be labeled as 3Gb/s.

Moreover, it is certainly crucial to have the ports labeled, especially if you are an amateur or you are working on your motherboard by yourself.

Modern SATA Ports And Their Versions

Nowadays, SATA ports come in three types or versions which are, SATA 1, SATA 2, and SATA 3.

SATA1 and SATA2 have 1.5 and 3.0 GB/s per second (gigabytes) respectively. Whereas, SATA 3 has the fastest throughput of the three at 6 Gb/s.

The shade of each SATA port varies depending on the type of motherboard along with the type of SATA port that it uses.

A motherboard with a single-slot SATA interface will majorly have no color to it. Nonetheless, motherboards that are old and have multiple SATA interfaces may have diverse colors. The blue color represents SATA3.

A SATA 3 compliant drive would be great for your needs if your motherboard has a SATA 3 port. This is because it can output the quickest achievable rates while making use of your motherboard’s high-speed capabilities.

SATA 2 connections, on the other hand, may look Red or Black and offer slower 3.0 Gb/s speeds.

Nowadays, most motherboards do not comprise SATA 2 or older versions of these ports, which is considered a good thing. Since we don’t want to have to search for the fastest SATA 3 ports, which are already popular, it becomes easier.


The controller modes for SATA dictate how the hard drive can communicate with your computer or laptop. The AHCI functions are also enabled when the raid mode is enabled.

The IDE mode is the most basic one. Advanced Host Controller Interface, often shortly known as “AHCI” mode allows advanced SATA features like hot swapping and Native Command Queuing to be used (NCQ).

RAID mode combines numerous hard disc drives into a single storage area (the array) to provide data redundancy (backup security) or quicker performance (striped data reading/writing from or to the disc drives).

You have now understood the fundamentals of a SATA interface. However, there are also additional storage interfaces that can give more performance and functionality.
