Usb to ide interface Pc#
Since the implementation of the ATA standard, the PC has changed dramatically. Over the years, these two factors have been more significant to mainstream PC users than high performance and as a result IDE rapidly became established as a mass market standard. The mass acceptance of the IDE standard hinged on its ability to serve the needs of the market in terms of two important criteria: cost and compatibility. IDE drives connect straight to the system bus with no need for a separate controller on the bus, thereby reducing overall cost. The separation of the controller logic from the interface made it possible for drive manufacturers to enhance the performance of their drives independently – there were no performance-boosting features incorporated into the ATA interface itself.
One of the major innovations introduced by IDE was the integration of the disk controller functions onto the disk drive itself. The parallel ATA standard evolved from the original IBM Advanced Technology (AT) interface and defines a command and register set for the interface, creating a universal standard for communication between the drive unit and the PC.
The term IDE itself is not an actual hardware standard, but the proposals were incorporated into an industry-agreed interface specification known as ATA (AT Attachment).
The IDE concept was initially proposed by Western Digital and Compaq in 1986 to overcome the performance limitations of earlier subsystem standards like ST506 and ESDI. One of the earliest and most significant standards introduced into PC hardware was IDE (Integrated Drive Electronics), a standard which controls the flow of data between the processor and the hard disk.
