I/O performance

I/O performance refers to how quickly a computer can read data from or write data to its storage devices, like hard drives or SSDs. Think of it as the speed at which information travels in and out of the system. High I/O performance means faster data transfer, leading to quicker access to files, smoother applications, and overall better responsiveness. Factors affecting I/O include storage device type, bus bandwidth, and system design. Improving I/O performance is crucial for tasks requiring rapid data access, such as database management, video editing, or running multiple applications efficiently.
