Abstract
A method includes receiving data to write to a memory sub-system including a single-level cell (SLC) cache and a multiple level cell (XLC) storage. The SLC cache includes a static SLC cache having a fixed size, and dynamic SLC cache having a default maximum size corresponding to a first mode of operation and an enhanced maximum size greater than the default maximum size corresponding to a second mode of operation. The method further includes, in response to determining to initiate a write operation in a first mode, initiating the write operation in the first mode to write a first portion of the data to the SLC cache, and in response to determining that a logical saturation of the first portion of the data satisfies the first threshold condition, continuing the write operation in the second mode to write a second portion of the data to the SLC cache.
