Editor to share with you what are the differences between hard disk ide mode and ahci mode. I hope you will get something after reading this article. Let's discuss it together.

Differences: 1, ahci mode supports hot swapping, ide mode does not support; 2, different operating range, ahci mode is operating serial ATA (SATA) host bus adapter, ide mode is operating parallel ATA driver; 3, ahci mode supports NCQ technology, ide mode does not support.

As SSD solid state drives have gradually become mainstream, AHCI mode has become more widely used, while IDE mode has been gradually eliminated. So what's the difference between ide mode and ahci mode? The following article will introduce you.

IDE mode

IDE (Integrated Device Electronics), integrated device circuit, is generally used as the interface of ATA hardware. It originally refers to the hard disk drive that integrates the "hard disk controller" with the "disk body". IDE mode can simulate the mapping of SATA disk to ordinary IDE hard disk without additional loading of SATA driver. However, no new features of the SATA interface are supported.

IDE mode belongs to parallel port transmission mode, that is, ATA mode, which is widely used before 2004. theoretically, the maximum data transmission speed is 133mb per second. AHCI mode belongs to new technology, which belongs to serial port transmission mode, that is, SATA mode. The transmission speed is also very fast, which can reach 300MB per second in theory.

Although IDE mode will be eliminated in information technology innovation, it is sometimes used in systems, such as the need to change to IDE mode in order to install systems that do not inherit SATA drivers. After the driver is installed, it should be called back to AHCI, otherwise the performance of the system can only be about 30%.

AHCI mode

AHCI (Serial ATA Advanced Host Controller Interface, Serial ATA Advanced Master Interface / Advanced Host Controller Interface) is an interface standard jointly developed by many companies under the guidance of Intel. It allows storage drivers to enable advanced serial ATA functions, such as native command queues and hot plug.

Its R & D team mainly includes famous enterprises such as Intel, AMD, Dell, Marvell, Maxtor, Microsoft, Red Hat, Seagate and StorageGear.

Advantages: 1. ACHI supports NCQ technology; 2. Read and write faster; 3. Hot swappable is supported.

The difference between ide mode and ahci mode

For the difference between AHCI mode and IDE mode, please refer to the following list:

AHCI

Definition: advanced host controller interface

Advantages: support for new technologies, such as native command queues

Hot plug (add / remove components while the computer is running): support

Cons: not always compatible

Founder: Intel

Operation range: operate serial ATA (SATA) host bus adapter

Operation mode: traditional parallel ATA simulation, standard AHCI or vendor-specific RAID

Operating system support: Windows Vista,7 and 8; Linux,OpenBSD,NetBSD,FreeBSD,OS Zjie eComStation and Solaris 10

IDE

Definition: IDE: integrated driver electronic devices / PATA: parallel advanced technology accessories

Advantages: maximum compatibility

Hot plug (add / remove components while the computer is running): not supported

Disadvantages: lack of support for new technologies such as native command queues and hot-swappable hard drives

Founder: Western Digital

Scope of operation: operate parallel ATA drivers

Operation mode: IDE

Operating system support: all

In fact, AHCI mode is a new type of hard disk algorithm, which can improve the performance of mechanical hard disk and make the system run faster. What is more advanced than IDE is that it can provide and support more functions.

These new features are the most critical reason to improve performance, such as NCQ technology, which is also a brand new technology. If you turn it on, it will increase the jump speed between programs. If you want to use this technology, you need to select AHCI mode from the hard drive, and then install the corresponding driver in the options.

If the AHCI driver is not installed in the system, the system will have a blue screen when it is turned on. At this time, you still need to adjust the need to IDE mode, manually install the driver of AHCI, and restart the system after modifying the registry.

After reading this article, I believe you have a certain understanding of "what are the differences between hard disk ide mode and ahci mode". If you want to know more about it, you are welcome to follow the industry information channel. Thank you for reading!
