Paragraph Number

29

"Logical block address" or "LBA" refers to a value used in a block storage device to associate each of n logical blocks available for user data storage across the storage media with an address. In certain block storage devices, the LBAs may range from 0 to n per volume or partition. In block storage devices, each LBA maps directly to a particular data block, and each data block maps to a particular set of physical sectors on the physical storage media. "User data" refers to data that a host directs a non-volatile storage device to store or record.
