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 Gb/s:
- Giga bit per second.
- 3 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).
- 4 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. - 5 bels:
- 1bels=10dB. Unit: sound pressure level.
- 6 ºC:
- degree C.
- 7 Depth:
- Excludes PCBA(Printed Circuit Board Assembly).
- 8 Depth:
- 1.5Gbit/s model does not support 3.0Gbit/s.
One gigabit (Gbit) = one billion bits. One megabyte (MB) = one million bytes. - 9 1.4W:
- 3.0Gbit/s operation.
- 10 Halogen-free:
- Halogen free as defined by levels of chlorine (CL) and bromine (Br) or a compound in which they are combined reduced to be
less than the standards of IEC61249-2-21:2003, as stated below:
Chlorine: less than 900ppm
Bromine: less than 900ppm
Chlorine + bromine: less than 1500ppm
