Performance
• 1200MB/s maximum instantaneous data transfers.
• 7200 RPM spindle. Average latency = 4.16ms
• Adaptive seek velocity; improved seek performance
• Background processing of queue
• Programmable multi-segmentable cache buffer
• Supports start and stop commands (spindle stops spinning)
.
There is no significant performance difference between Self-Encrypting
Note
Drive and standard (non-Self-Encrypting Drive) models.
3.3

Media description
The media used on the drive has a glass substrate coated with a thin film magnetic material, overcoated with a proprietary protective layer for
improved durability and environmental protection.

Formatted capacities
Standard OEM models are formatted to 512 bytes per block for 512 emulation 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 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.
