LBA
LBA (Logical Block Architecture). Originally hard disks had no local intelligence, so they were addressed by selecting the cylinder, then track then sector. Now the computer just tells the disk the linear sector number range it wants to read or write. The disk itself sorts out which cylinder, track and sector that the data lives on or where it is in cache. Nearly all drives today use 48-bit LBA.
