Abstract
Systems, methods and/or devices are used to enable using history of I/O sizes and I/O sequences to trigger coalesced writes in a non-volatile storage device. In one aspect, the method includes (1) receiving a plurality of input/output (I/O) requests to be performed in a plurality of regions in a logical address space of a host, and (2) performing one or more operations for each region of the plurality of regions in the logical address space of the host, including (a) determining whether the region has a history of I/O requests to access data of size less than a predefined small-size threshold during a predetermined time period, (b) determining whether the region has a history of sequential write requests during the predetermined time period, and (c) if both determinations are true, coalescing subsequent write requests to the region.
