In a data storage hierarchy, such as a random-access cache servicing a data storing disk file, the time delays caused by a write miss (no space allocated in cache for received data) is minimized by pipelining allocation of space in the cache with the transfer of data from a host processor. Allocation of cache data space can occur during data transfers from a connected host processor for enabling expected data to be received from the host processor to be immediately lodged in the cache resulting from a write cache hit. The host processor is connected to a backing data storage, such as a data storing disk file, main memory of a processor, and the like, via a data cache. Provisions are made for bypassing the cache.
