Adjusting characteristic of system based on profile
Various embodiments described herein provide for operation of a memory sub-system based on a profile (also referred to herein as an operational profile) that causes the memory sub-system to have a specific set of operational characteristics. Additionally, some embodiments can provide dynamic switching between profiles based on a set of conditions being satisfied, such as current time of day or detection of a particular data input/out (I/O) pattern with respect to the memory sub-system.
