Fundamentals of Disk I/O Usage

Disk I/O Input/Output (I/O) refers to the transfer of data between storage devices (hard drives, SSDs, etc.) and main memory (RAM) in a computer system. This process is critical for the proper functioning of applications and the operating system. Any application's process of reading or writing data Disk I/O triggers activity and the speed of these activities directly affects system performance.

Disk I/O The fundamental elements of disk usage include read and write operations. Read operations retrieve data from storage devices, while write operations store data on them. Each of these operations can have different performance characteristics and impose different system-wide loads. For example, intensive write operations can shorten the disk's lifespan and lead to performance issues.
