Logical Block Address Configuration
Each device is set to report its logical block address (LBA) settings, which ensure suffi-
cient storage per device capacity. The tables below show LBA settings according to de-
vice size.
Standard OEM models are formatted to 512 bytes per block. The block size is selectable
at format time, and users with the necessary equipment can modify the data block size
to capacities different than those listed below before issuing a format command. To
provide a stable target capacity environment while also providing users with flexibility,
Micron recommends product planning.
Micron ensures that current and future product generations will meet capacity points at
certain block sizes. Planning with this in mind ensures a stable operating point with
backward and forward compatibility across product generations. The current operating
points for each device are shown below. The capacity stated is identical when the drive
is formatted with or without PI enabled.
Programmable Drive Capacity
Using the MODE SELECT command, users can change the drive capacity to less than its
maximum value. A value of zero in the Number of Blocks field means that the MODE
SELECT command will leave the drive capacity unchanged. A value greater than zero
and less than the maximum number of LBAs in the Number of Blocks field means that
the MODE SELECT command will change the drive capacity to the value in the Number
of Blocks field. A value greater than the maximum number of LBAs means that the
MODE SELECT command will round down to the maximum capacity.
