A standard ISO file is a sector-by-sector copy of a physical disc, including the file system and "padding"—empty data (often just zeros) used by developers to fill the disc and improve reading speeds on original hardware. "Highly compressed" versions use various methods to eliminate this excess: The world of "highly compressed" PS2 ISOs is
While the decompression process requires CPU power, the storage footprint is smaller. This benefits older laptops with small SSDs.
