Formatted capacities
Standard OEM models are formatted to 512 bytes per block for 512 emulation and native drives and 4096 bytes per block for 4096
native drives. The block size is selectable at format time. Supported block sizes are 512, 520 and 528 for 512 emulation and native
drives and 4096, 4160 and 4224 for 4096 native drives. Users having the necessary equipment may modify the data block size before
issuing a format 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 modes:
Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will meet. We
recommend customers use this capacity in their project planning, as it ensures a stable operating point with backward and forward
compatibility from generation to generation. The current guaranteed operating points for this product are shown below.
Note
There is no significant performance difference between Self-Encrypting
Drive and standard (non-Self-Encrypting Drive) models.
