In computer storage, a disk buffer (often ambiguously called a disk cache or a cache buffer) is the embedded memory in a hard disk drive (HDD) or solid-state drive (SSD) acting as a buffer between the rest of the computer and the physical hard disk platter or flash memory that is used for storage. [1]
Pages in the page cache modified after being brought in are called dirty pages. [5] Since non-dirty pages in the page cache have identical copies in secondary storage (e.g. hard disk drive or solid-state drive), discarding and reusing their space is much quicker than paging out application memory, and is often preferred over flushing the dirty pages into secondary storage and reusing their space.
High-end disk controllers often have their own on-board cache for the hard disk drive's data blocks. Finally, a fast local hard disk drive can also cache information held on even slower data storage devices, such as remote servers ( web cache ) or local tape drives or optical jukeboxes ; such a scheme is the main concept of hierarchical storage ...
Disk cache may refer to: . Disk buffer, the small amount of RAM embedded on a hard disk drive, used to store the data going to and coming from the disk platters; Page cache, the cache of data residing on a storage device, kept by the operating systems and stored in unused main memory

This data will be recreated every time you visit the webpage, though at times it can become corrupted. Clearing the cache deletes these files and fixes problems like outdated pages, websites freezing, and pages not loading or being ...
A hard disk drive (HDD), hard disk, hard drive, or fixed disk [a] is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.
