disk access patterns

Disk access patterns refer to the ways data is read from or written to a storage device, such as a hard drive or SSD. These patterns can be sequential, where data is processed in order, or random, where data is accessed in a non-linear fashion. Sequential access is typically faster because it allows for continuous reading or writing, while random access can lead to delays as the device seeks different locations. Understanding these patterns helps in optimizing performance, enabling quicker data retrieval and improved overall efficiency in computing tasks.
