Abstract
A method of operating a storage device including a non-volatile memory includes: the storage device receiving from a host a first write command; determining, based on the first write command, whether first write data for the first write command is sequential data required to be written according to a write request order; writing the first write data in the non-volatile memory; and when the first write data and second write data for a second write command are sequential data, sequentially updating first mapping data including a mapping relationship between a first logical address and a first physical address for the first write data, and updating second mapping data including a mapping relationship between a second logical address and a second physical address for the second write data, according to an order in which the first write command and the second write command are received.
