write-through cache

A disk or memory cache that supports the caching of writing. Data written by the CPU to memory or to disk is also written into the cache. Write performance is not improved with this method. However, if a subsequent read operation needs that same data, read performance is improved, because the data are already in the high-speed cache. See write-back cache and cache.
