Abstract
In general, techniques are described for stream management in storage devices. A storage device comprising a memory device and a processor may be configured to perform the techniques. The processor may detect a stream collision in which a host device writes a first version of a logical block (LB) to a first stream, and writes a second version of the same LB to a second stream. The processors may compare a first blockset sequence number (BSN) associated with a first collection of physical blocks referenced by the first stream to a second BSN associated with a second collection of physical blocks referenced by the second stream. Based on the comparison of the first BSN to the second BSN, the processor may write, to the mem device, the second version of the LB to the first stream.
