write-through cache A technique for handling host write requests in read caches. When the host requests a write operation, the cache writes data directly to the external storage device and updates the cache memory to ensure that the memory does not contain obsolete data. This technique increases the chances that future host read requests can be filled from the cache. The host sees the write operation as complete only after the external storage device has been updated. See also read cache. Glossary–18
