Most repositing devices silent use the SATA interface to connect to your personal computer, so the question arises, does it ’ mho specifics affect your personal computer ’ second performance ? SATA version 3.0 was introduced in 2009 and was promised to have double the speed of its predecessor SATA 2.0 and in this article, we will discuss the real-life difference between the versions and the gear related to them .
What Is SATA?
SATA ( Serial ATA ) is an IDE (Integrated Drive Electronics) standard, which basically to a consumer means plugs, connectors, and cables that allow storage devices to connect to the motherboard, allowing data transfer. storage devices, in this event, means HDDs ( Hard Disk Drives ), SSDs ( Solid State Drives ), and CD drives.
many people might still remember huge, two-dimensional cables in older computers – those were PATA ( Parallel ATA ) cables, that have been gradually replaced by SATA cables since the early 2000s .
same as with all technology, the SATA interface has gone through a few iterations to fit modern standards. SATA has had 3 notable versions as of right field now : digression from a few, minor differences, like NCQ ( Native Command Queuing, introduced in SATA 2.0 ) that allows hard drives to go through commands faster, the main difference between SATA versions 2.0 and 3.0 is the data transfer speed they can provide. SATA 1.0 is a dependable as extinct these days, with no fresh computers using this connection, so there is nothing extra to discuss in this cable away from it kicking off the development of SATA all in all. All three connection and cable versions are compatible, making data speed difference between cables an issue we have addressed further in the article .
Basic SATA connectors are located inside the personal computer, therefore letting you only connect home storage devices. This is why eSATA ( external-SATA ) has become pretty popular. eSATA, aside from overall lastingness and better shielding from away electromagnetic fields, is simply a regular SATA connection located on the buttocks of your personal computer, similar to VGA ( display ) or USB connectors. This allows external storage devices to be connected to your personal computer. The eSATA socket is basically connected to your SATA interface on your motherboard which is why the translation of eSATA you can get ( or already have ) on your personal computer depends on the one your motherboard supports .
Is eSATA Even Useful?
While it may seem virtual to keep external devices, the SATA joining doesn ’ metric ton provide a device with world power, many external drives don ’ t even reach the transfer speeds of SATA 3.0, plus many personal computer ’ sulfur may require you to buy the port bracket ( like this 2 port SATA to eSATA bracket ) and install it, so why use it instead of USB? The SATA interface has been thoroughly improved over the years with many tweaks and protocols that improve how your storage devices work, as opposed to the jack of all trades USB, which has to manage a million other things aside from storage. not alone that, USB splits its 5 GB/s transfer accelerate over all the connectors, so if your personal computer has a decent amount of peripherals, that amphetamine may be cut sol abruptly that it bottlenecks the datum a faster external drive can send.

With slower external drives you may want the practicality of one USB cable television rather of two since you won ’ metric ton be able to reach the soap speeds that either peripheral can handle, however, faster drives should be connected via eSATA in club to use their potential to the soap .
Knowing Your Cables
All these different standards, connectors, and speeds may confuse you a bit but at least the region some people worry about the most when working with their SATA interface is rather simple. All internal SATA cables are not only compatible but are besides the same across all versions ( proven by a little experiment here ). For exercise, you could use what is marked as SATA 1.0 cable with a SATA 3.0 device & motherboard and not lose any transmit accelerate, which basically means that “ SATA III cable ” is basically a selling term to make it sound modern and better .
This, however, doesn ’ thymine mean that ports of different SATA versions won ’ thyroxine cut down speeds. For model, a SATA 3.0 unvoiced drive connected to a SATA 2.0 port, depending on what you use that hard tug for, may lose a pretty large amount of speed due to the bottleneck on your motherboards side .

You can check what your motherboard ’ s adaptation of SATA is in its manual .
eSATA, on the early hand, has its own connector to ensure signal shielding, better signal remove, and lastingness outside of your personal computer encase, therefore eSATA connection is not compatible with SATA. While the cable itself is different, the same principle as with SATA cables applies here excessively – there is no version to an eSATA cable, different “ versions ” of cables don’t affect your transfer speeds .
SATA doesn ’ triiodothyronine provide power to devices through its data cables ( like USB does ), which is why SATA drives frequently use 22-pin connectors. 22 is basically the 7 pins that any SATA data cable television has plus 15 pins that are used to supply ability. Devices may besides use a Molex connector for ability – this is a white, more squarish connection with 4 big plugs. When it comes to external intemperate drives, many of them use USB ports for exponent. All 4 of these are easy to distinguish, as seen in the photograph below.

To Sum Up …
- SATA is the connection made specifically for connecting storage devices to your PC, making them the main choice of manufacturers.
- SATA 2.0 provides half the speed of SATA 3.0 – 3GB/s to 6GB/s respectively. The only other differences are minor internal process optimizations.
- When purchasing a SATA or eSATA storage device, make sure your motherboard’s version of SATA can handle the version that the device has.
- SATA and eSATA cables are not compatible, however, there is no difference between cables of different versions, i.e. SATA 3.0 cable is the same as a SATA 2.0 cable, eSATA 3.0 cable is the same as eSATA 2.0 cable.
