*1: Capacity under the LBA mode.
*2: One gigabyte (GB) = one billion bytes and One megabyte (MB) = one million bytes; accessible capacity will be less and actual capacity depends on the operating environment and formatting.
*3: 1 GB is equal to 1,000,000,000 bytes and 1 MB is equal to 1,000,000 bytes.
*4: 1.5 Gbps model does not support 3.0 Gbps.
*5: 1 MB is equal to 1,048,576 bytes; the actual buffer capacity for data transfer will be less. Refer to the Section 6.4 of this manual.
*6: The value of Depth (=100.0 mm) does not include PCBA (Printed Circuit Board Assembly). For details, see Section 3.1.
