16. A storage system comprising:

a processing resource; and

instructions that when executed by the processing resource cause the storage system to:

create a sample to facilitate generation of one or more metrics pertaining to a characteristic relating to a state of compression, compressibility, or a type of data stored in a subset of blocks of the storage system by statistically sampling block identifiers (IDs) of the subset of blocks;

determine a first metric for data having the characteristic within the sample by, for each block ID within the sample, analyzing one or more of metadata associated with a block to which the block ID corresponds and data contained in the block; and

extrapolate a second metric for data having the characteristic within an entirety of the subset of blocks based on the first metric.
