Handling ordered writes to a data storage device includes receiving a first chunk of data into slots of a cache of the data storage device and using a hash table to provide a correlation between cache slots containing data from the first chunk of data and locations of a logical storage device of the data storage device. For example, in accordance with an embodiment of the present invention, a master delay circuit may digitally control one or more slave delay cells to support various applications of a programmable logic device. An internal radial feed tube supplies coolant from the annular coolant manifold to the flow path in the tool. Several features make the box secure against weather and tampering. The method further includes receiving a first performance enhancement indicator in at least one clock cycle after ending the first address segment while before starting to transfer data, for determining whether an enhanced operation is to be performed.
