Techniques described herein may be used for reducing the usage of sensors during thermal throttling in storage devices. A memory of a storage device may store map tables, each map table associated with a type of host command, each map table including entries, each entry corresponding to an initial temperature level and characteristics of a host command, and each entry indicating a change in temperature relative to the initial temperature level. A controller of the storage device may monitor operations for commands from the host system, obtain an initial temperature value from one or more temperature sensors, select entries from the map tables, based on characteristics of the operations and the initial temperature value, predict a current temperature based on the one or more entries, and in accordance with a determination that the current temperature exceeds a predetermined threshold, trigger one or more corrective actions for thermal throttling.

Simulating multi-sensor environment for thermal throttling in storage device

A data storage device comprising a data port, configured to transceive data via a wired communication channel, a control port, configured to transceive data via a peer-to-peer wireless communication channel, a non-volatile storage medium, and a controller. In response to receiving, from a user device, via the control port, a command to enable control channel access, the controller performs an unlocking process, and, in response to completing the unlocking process, transitions from a locked state to a control channel access state. In response to being in the control channel access state, and in response to receiving, from the user device, via the control port, a write command, the controller stores write data in the storage medium, and, in response to receiving, from a host computer, via the data port, a command to access the storage medium, the controller transmits, to the host computer, a locked state indication.
