resulted in a maximum drive capacity of two gigabytes. Later, the first formalized ATA specification used a 28-bit addressing mode through LBA28, allowing for the addressing of 2²⁸ sectors (blocks) of 512 bytes each, resulting in a maximum capacity of 128 GiB (137 GB).

ATA-6 introduced 48-bit addressing, increasing the limit to 128 PiB (144 PB). As
