Integrity: ISO files are raw dumps. If an ISO is corrupted, it is often unusable. CHD files contain internal checksums (verification data) that allow emulation software to verify the integrity of the game data.

Important note for 2021 hardware: Running games from an SSD vs. HDD in 2021 showed no performance difference between CHD and ISO. The decompression overhead is handled by your CPU, so if you have a modern (2021 mid-range) Ryzen or Intel Core i5, you will see zero lag. Integrity: ISO files are raw dumps

The barrier to entry for CHD conversion lowered significantly in 2021 due to the availability of tools:
