Host workload based address table update management in data storage devices

A storage device to improve random write processing and performance on the storage device, the storage device comprises:

• a persistent memory to store a logical-to-physical (L2P) table that includes a mapping of logical block addresses in a host command to physical addresses on the persistent memory;
• a volatile memory including a cache address table to store msets in the L2P table and a ulayer to store updates to msets in the L2P table;
• and
• a controller to receive a host write command, track a set of incoming host commands to determine a host workload, trigger a first state on the storage device based on a first host workload, disable interaction with the cache address table and update the ulayer with mapping information in the host write command while the storage device is in the first state, and trigger a second state on the storage device based on a second host workload and enable interaction with the cache address table while the storage device is in the second state.

A method for improving random write processing and performance on a storage device, the storage device comprises a controller to execute the method comprising:

• receiving host commands;
• tracking a set of incoming host commands to determine a host workload;
• triggering a first state on the storage device based on a first host workload;
• and
• disabling interaction with a cache address table and updating a ulayer with mapping information in the host command while the storage device is in the first state.
