Difference between AHCI and IDE

By Jaxson

Main Difference

“AHCI “and “IDE” are 2 forms in which a hard drive connected with the rest of the computer system with an (SATA) storage controller. “SATA “hard drives can run in a backward-compatible (PATA/IDE) mode, a regular AHCI mode or vendor-specific” RAID”. AHCI knew as” Advanced Host Controller Interface” and is a more rapid form of the procedure as compared to” IDE”. RAID form as well as enablers in addition to making use of AHCI. The AHCI provides a standard method that software designers and developers can use to organize, identify, detect, program AHCI /SATA adapters. Note that even though AHCI taps into the additional and highly developed characteristics of SATA for host systems, it is a split standard as of those set for SATA.


AHCI ‘Advanced Host Controller Interface AHCI’ is a technical standard distinct from Intel that specifies the procedure of Seria (ATA /SATA) host bus adapters in a non-implementation-specific style. The requirement describes a system memory formation for computer hardware vendors to exchange information between a host system memory and fond of storage devices. AHCI gives hardware designers and software developers a customary method for identifying the problem, detecting, configuring, and encoding (SATA/AHCI) adapters. AHCI is a separate type of the SATA standard, even though it exposes SATA’s advanced capabilities such that host systems can operate them. Numerous SATA controllers offer selectable methods of operation: legacy Parallel ATA imitating, standard AHCI mode (otherwise called local mode), or seller particular RAID (which by and large empowers AHCI so as to exploit its abilities). Intel suggests picking RAID mode on their motherboards (which likewise empowers AHCI) as opposed to AHCI/SATA mode for most extreme flexibility. Legacy mode is a product in reverse similarity instrument expected to permit the SATA controller to keep running in legacy working frameworks which are not SATA-mindful or where a driver does not exist to make the working framework SATA-mindful. When an SATA controller is arranged to work in legacy mode, the quantity of capacity gadgets per controller is generally restricted to four (two IDE channels, essential and optional, with up to two gadgets for each channel), contrasted with the most extreme of 32 gadgets/ports when designed in AHCI mode.


IDE is a software application that gives extensive services to computer programmers for software development and program design. An IDE usually contains a source code editor, debugger, and build automation tools. The majority contemporary IDEs have intelligent code completion. Some IDEs holds an interpreter, compiler, or both, such as Eclipse and NetBeans, others do not, such as Lazarus and SharpDevelop. The margin between an integrated development environment and extra parts of the broader software development environment is not precise. Sometimes various tools and a different version to control system shorten the creation of a ‘Graphical User Interface (GUI)’, are integrated. A lot of present IDEs also have an object browser, a class browser and class hierarchy sketch, for use in object-oriented software development. One major benefit that you will obtain by using the IDE is composed of decreasing the design important to sort out different advancement utilities, rather giving the same arrangement of capacities as a firm unit. Lessening that setup time can build engineer profitability, in situations where figuring out how to utilize the IDE is quicker than physically coordinating the greater part of the individual instruments. More tightly incorporation of all advancement assignments can possibly enhance general profitability past simply assisting with setup undertakings. For instance, code can be consistently parsed while it is being altered, giving moment criticism when language structure mistakes are presented. That can speed taking in another programming dialect and its related libraries.

Key Differences

  • This has been the normal line that is used for storage space e.g: hard drives and optical drives for a substantial length of time. While there were a few problems at the commencement, the standard was ultimately perfected and wide-ranging drives from diverse manufacturers can put mutually most CPU. IDE was obsolete by SATA as it introduced at several of advantages. AHCI is an application programming line that describes one type of operation for SATA. AHCI does not influence the speed at which SATA drives function, however, it exposes the advanced characteristics that be with SATA.
  • To sustain outdated compatibility with older hardware, mainly SATA controllers provide you with the option of which operating approach you want to use. Operation function contains AHCI and IDE, often referred to as heritage IDE or native IDE, between others so that you have liberty. Selecting IDE as your form of operation is just similar to having a good old consistent IDE drive but lacking the advantage of AHCI.
  • Unlike the IDE, the AHCI interface supports the hot plugging.
