Abstract
In one embodiment, a solid state storage drive comprises a plurality of flash memory devices communicatively coupled to a bus and a channel controller communicatively coupled to the bus, the channel controller comprising an execution time calculator configured to determine an aggregate execution time duration for a sequence of commands in a command execution queue based on a data transfer rate presently assigned for communications over the bus, and a channel execution unit configured to determine when to place a second command in a command execution queue based at least in part on the aggregate execution time duration. In one embodiment, the execution time calculator is further configured to determine the aggregate execution time duration based on the data transfer rate and a data payload quantity associated with at least one command in the sequence of commands.
