write back caching
A controller process that notifies the host that the write operation is complete
when the data is written to the cache. This occurs before transferring the data to
the disk. Write back caching improves response time since the write operation
completes as soon as the data reaches the cache. As soon as possible after
caching the data, the controller then writes the data to the disk drives.
write caching
A process when the host sends a write request to the controller, and the controller
