What is Cache?
Cache is the memory incorporated in the hard disk that stores frequently- accessed data. This saves use of the read/write head, thus extending its life, besides, obviously, improving performance. A 2 MB cache is common in most hard drives, with the highest being 16 MB in the latest, large-capacity drives. The maximum transfer speeds of the interface that is mentioned in the drive specifications refers to the time it takes for the cache to send the data.
