Specifications are subject to change without notice.
- 1 GB:
- One gigabyte (GB) = one billion bytes; accessible capacity will be less and actual capacity depends on the operating environment and formatting.
- 2 1.8W:
- At 3Gbit/s.
- 3 3Gbit/s:
- 1.5Gbit/s model does not support 3.0Gbit/s.
One gigabit (Gbit) = one billion bits. One megabyte (MB) = one million bytes. - 4 Depth:
- The value of Depth does not include PCBA (Printed Circuit Board Assembly).
- 5 Power:
- When the operation (command) that accompanies a transfer of 63 sectors is executed 3 times in 100ms.
- 6 Rank:
- Energy efficiency based on the Law Concerning the Rational Use of Energy indicates the value obtained by dividing power consumption by the storage capacity (Japan only).
- 7 MB:
- One megabyte (MB) as 1,048,576 bytes for Hard Disk Drives' cache size.
Small portion of buffer memory is used for drive firmware control. - 8 bels:
- 1bels=10dB. Unit: sound pressure level.
- 9 ºC:
- degree C.
- 10 Operating:
- Without non-recovered errors.
- 11 Non-operating:
- No-damage.
