Claim 0:
1. An operation method of a storage device including a nonvolatile memory device, the method comprising:
receiving a first write request from an external host;
adding the first write request to a first fragment;
selecting “n” streams among a plurality of pre-allocated streams having a cosine similarity higher than a threshold with respect to the first fragment when a size of the first fragment is greater than or equal a reference value, where “n” is a natural number of at least two;
applying statistical information of the “n” streams and the first fragment to a machine learning model to detect a first sequential stream associated with the first fragment from among the “n” streams;
allocating a stream identifier of the first sequential stream to the first fragment; and
storing, in the nonvolatile memory device, write data included in the first fragment based on the allocated stream identifier of the first sequential stream.
