Abstract: In a method of operating a memory system disclosed, whether a first condition is satisfied is determined. The first condition is associated with free blocks and garbage collection (GC) target blocks from among a plurality of memory blocks. In response to the first condition being satisfied, a size of a data sample associated with executions of a host input/output request and GC is adjusted. The data sample is generated based on the adjusted size of the data sample. The data sample includes a downscaled current valid page count (VPC) ratio and the first number of previous host input/output request to GC processing ratios. A current host input/output request to GC processing ratio is calculated based on the data sample. The host input/output request and the GC are performed based on the current host input/output request to GC processing ratio.
