4.5 Formatted capacities Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time and must be a multiple of 4 bytes. Users having the necessary equipment may modify the data block size before issuing a FORMAT UNIT command and obtain different formatted capacities than those listed. To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate recommends product planning in one of two mod

4.8 Thin Provisioning 4.8.1 Logical Block Provisioning The drive is designed with a feature called Thin Provisioning. Thin Provisioning is a technique which does not require Logical Blocks to be associated to Physical Blocks on the storage medium until such a time as needed. The use of Thin Provisioning is a major factor in SSD products because it reduces the amount of wear leveling and garbage collection that must be performed. The result is an increase in the products endurance. For mor

When a region of LBA's are erased via cryptographic erase, as part of the erase, the drive shall unmap those LBAs. If the host attempts to access an unmapped or trimmed LBA, the drive shall return scrambled data. For a given LBA, the data shall be identical from access to access, until that LBA is either updated with actual data from the host or that LBA is cryptographically erased. The drive shall report a value of '0' in the LBPRZ field returned in the READ CAPACITY (16) parameter data. If
