What is a SATA Hard Drive? User Guide For DIYers

Old computer set ups can be costly overtime, especially when you have had a number of hard drives data recovery service done on it. If you are thinking about upgrading or building a new computer, you may eventually run into SATA.

SATA drives can help alleviate some of the stress of computer maintenance. SATA Drives are reliable and proven technology. They are perfect for non-demanding use.

What is a SATA hard drive? - Complete Definition!

The SATA (Serial ATA) hard drives is the successor of the traditional PATA (Parallel ATA) Hard drives. It became the central mass storage device on PC. Serial Advanced Technology Attachment, also known as SATA is the new standard for connecting and transferring data components inside of your computer.

What is a SATA hard drive in the flesh is that it’s a bus interface that connects host bus adapters to mass storage devices. SATA is a serial linka single cable with at least four wires that form a point-to-point connection between devices.

You can find SATA Hard Drives inside of your desktop computers, laptops, or servers. It is a type of rewritable mass storage devices.

SATA Hard Drives are characterized by good transmission speeds and outstanding storage capacities. They are also supported by virtually all operating systems and computer motherboards.

For several years, it was the most common and the least expensive interface for internal computer storage devices. PATA started to fade away when the SATA was introduced in 2003.

What Are The SATA Interface Revisions?

SATA I was released in 2003, Following that is SATA II in April 2004. SATA Interface 3.0  was introduced on May 2009 followed by Revisions 3.2, 3.3 in 2011 and 2016 respectively.

Here’s a complete overview of the SATA hard drives evolution:

SATA Revision 1.0

The first version of the SATA interface was released in 2003. It’s devices topped out at a transfer rate of 1.5 gigabits per second. The SATA Revision 1.0 devices were commonly used in office desktops and personal computers, and were configured from PATA drives joined together in a master/slave configuration.

SATA Revision 2.0

In April 2004, Native Command Queuing (NCQ) was introduced. This feature allows the drive to perform write/read commands that are transferred randomly. This function helps to optimize the movement of the reading head.

SATA Revision 2.0 devices have a transfer speed increased by double. It rises up to 3.2 gigabits per second or 400MB/s with the addition of port multipliers, port selectors, and improved queuing.

SATA Revision 3.0

The full SATA revision 3.0 standard was released on May 27, 2009. These interfaces support drive transfer rates up to 6 gigabits per second. SATA Revision 3 drives are back compatible with SATA Revision 1.0 and SATA Revision 2.0 devices, but with a lesser transfer speed.

SATA Revision 3.1

Released in July 2011, it is a transitional revision that added final design requirements for SATA Universal Storage Module for consumer-based portable storage applications. This revision introduced or changed the following features:

SATA Revision 3.2

Released in August 2013, this revision presented the SATA Express (SATAe). It supports the real-time use of SATA ports and PCI Express (PCIe) lanes. This made it possible for legacy SATA and PCI Express storage devices to exist together.

SATA Revision 3.3

Released in February 2016, this revision introduced the following features:

What Are The Advantages of SATA Hard Drive over PATA?

The main advantage of SATA is it’s 150MB/s min speed, SATA is also equipped with Native Command Queuing (NCQ) while PATA isn’t, and lastly, SATA are hot-pluggable and PATA drives are not.

SATA (Serial ATA) is the replacement to PATA (Parallel ATA), the two are interfaces that used to connect to storage devices such as hard drives and optical drives. These are advantages of SATA over PATA:
