 Description   

Enable block checksums even when compression is enabled on all new collections and indices. Previously, checksum was enabled only on blocks which are not compressed for any reason.

The performance impact is negligible on most workloads, but can be configured on individual collections and indexes. WiredTiger documentation for checksum configuration is here.
