Hard disks are the data storing units and hence, they are an integral part of the computer without which the system cannot operate. Since the continuous development of computers throughout the years, hard disks also needed to evolve to cope up with new technology. There have been many types of hard disks till now, two of which are SATA and IDE hard disks.
SATA Hard Disk vs IDE Hard Disk
The main difference between SATA hard disk and IDE hard disk is that SATA hard disks are based on the latest technologies and are future-proof whereas IDE hard drives lack support for new technology. Even though the purpose of both the hard disks is similar, they vary a lot in how they operate and what systems are they compatible with.
SATA hard disk is a type of rewritable mass storage device that has excellent transmission speeds, large storage capacities, and is compatible with all operating systems and computer motherboards. Not only in computers and laptops, but SATA hard disks are also compatible with video gaming consoles, including the PlayStation 4, Xbox 360, etc.
IDE hard disk is a hard disk that was earlier used in computer systems that required both reliable and non-volatile data storage types. These hard disks are the easiest to install drives into the system by removing the difficulties with the division of the components and controllers. IDE was a major upgrade from its predecessor.

|Data Transfer Speed||Data transfer rate up to 6 Gbps.||Data transfer rate up to 133 Mbps.|
|Hot-Plugging||Supports hot-plugging.||Does not support hot-plugging.|
What is SATA Hard Disk?
SATA stands for Serial Advanced Technology Attachment. SATA hard disk is a type of rewritable mass storage device that has excellent data transfer speeds, large storage capacities, and is compatible with all operating systems including Windows, Kali Linux, etc., and various motherboards. SATA hard disks are reliable for approximately 3 to 4 years at maximum.
Introduced in 2003, SATA is the pre-installed interface for almost all computer laptop hard disks. A SATA hard disk when launched was exceptionally faster as compared to its predecessor. A SATA hard disk can write to the disk with a maximum interface data transfer rate of 6 Gb/s. This hard disk has a capacity ranging from 500 GB to 16 TB. SATA hard disks are hot-pluggable as well which means that the user can remove or attach drives without having to shut the whole system down. One major con of SATA hard disks is that they require regular de-fragmentation.
Since its launch in 2003, there have been six revisions of SATA hard disks. SATA Revision 3.3, the latest SATA hard disk was launched in the year 2016. This build offered many upgrades and new features including SMR support, transmitter emphasis, and power disables, etc.
What is IDE Hard Disk?
IDE stands for Integrated Drive Electronics. IDE hard disks were launched in 1986 by a company named Western Digital. They are relatively slow by today’s standards. They have a maximum data transfer speed of up to 133 Mbps and a maximum capacity of 1 TB. IDE hard disk is connected to the computer’s data bus via the IDE interface. These hard disks are now outdated in today’s technology.
IDE hard disks are different than other hard disks because their controllers are on each drive which means that the hard disk is directly connected to the system’s motherboard or the controller. IDE hard disks are very easy to install and generally need no technical help. The data on IDE hard disks need to be regularly backed up as they can crash on extensive load. They have less speed and inferior overall performance by today’s standards of hard disks. Users are also more prone to electrical shocks with these hard disks as hot-plugging is not available in IDE.
When SATA hard disks completely took over the market in 2007, the production of IDE hard disks stopped as they were simply not comparable to SATA. With SATA offering better performance, IDE hard disks are now outdated.
Main Differences Between SATA and IDE Hard Disk
- SATA hard disk has 8TB of maximum capacity and IDE Hard Disk has 1TB. Hence, SATA can store 8 times more data than IDE.
- Data transfer speed in SATA hard disk can go up to 6 Gbps whereas IDE hard disk can only go up to 133 Mbps, which is relatively slow.
- SATA hard disks are sold in large numbers whereas IDE hard disks stopped manufacturing in 2007.
- SATA hard disk’s configuration is complex for most people whereas IDE hard disks have a rather simpler configuration.
- SATA cables have increased airflow as compared to IDE cables. As a result, less heat is developed in the motherboard.
Introduced in 1986 and 2003 respectively, both SATA and IDE hard disks are pretty old. As of today, SATA and IDE have now been overshadowed by newer technologies of hard disks available at faster speeds and better performance. SATA hard disks are still a resource as not all systems have been updated to the latest technologies. IDE, on the other hand, is almost negligible in the market.
At the time of its release, IDE hard disks set a benchmark in the technology of hard drives. As it was developed for the early stages of computers, the performance was top-notch for a 1986 computer system. It was a significant improvement from its predecessor, and hence it provided the path for new technologies to emerge. But after the introduction of a newer generation of computers, SATA hard disks were also introduced to keep pace with computers. As the demand for the latest computer systems increased the sales of SATA also rose. As a result, SATA hard disks took over IDE. With the technology growing, even more, there are newer hard disks including SSD, HDD, etc. which offer even better performance. By today’s standard, even SATA hard disks are left behind in performance. However, SATA hard drives are still valuable as they can hold terabytes of data compared to IDE whose production stopped more than a decade ago.
