    Hawk 2XL Product Manual, Rev. B The following is a simplified description of a read operation with cache operation enabled: Case A - A Read command is received and the first logical block (LB) is already in cache: 1. Drive transfers to the initiator the first LB requested plus all subsequent contiguous LB’s that are already in the cache.

If the host uses software interleave, ARLA enables prefetch of contiguous blocks from the disk when it senses that a prefetch “hit” will likely occur, even if two consecutive read operations were not for physically contiguous blocks of data (e.g.
