Looking ahead, CHD seems poised to become the standard compression format for disc-based game preservation. Its combination of lossless compression, wide emulator support, and active development makes it an ideal choice for both casual collectors and serious preservationists.
CHD files use advanced compression algorithms that require processing power for decompression. On very low-end hardware (e.g., older smartphones or budget retro handhelds), CHD files may load slightly slower than uncompressed ISOs. However, for most modern devices, the performance difference is negligible, and the storage savings outweigh any minor speed penalty.
