Abstract
A method may involve: receiving a request to perform a block write to a target device and data associated with the block write; buffering the data associated with the block write prior to completing the block write to the target device; storing an indication identifying a block address range of the block write; receiving a request to perform a read to the target device; and determining whether an address of the read is within the block address range of the block write identified by the indication. In some embodiments, such a method may allow the read to complete ahead of the block write dependent on whether the address of the read is within the block address range of the block write identified by the indication.
