Specification Sheet

WD VelociRaptor VR200M

Enterprise Hard Drives

1 As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte
(TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one
megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per
second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 6 Gb/s transfer rate calculated
according to the Serial ATA specification published by the SATA-IO organization as of the date of this specification sheet. Visit
www.sata-io.org for details.
2WD hard drive products manufactured and sold worldwide after June 1, 2006, meet or exceed Restriction of Hazardous
Substances (RoHS) compliance requirements as mandated by the European Union for electrical and electronic products. The
RoHS Directive 2002/95/EC of the European Parliament, which is effective in the EU beginning July 1, 2006, aims to protect
human health and the environment by restricting the use of certain hazardous substances in new equipment, and consists of
restrictions on lead, mercury, cadmium, and other substances.
3 Controlled unload at ambient condition.
4 No non-recoverable errors during operating tests or after non-operating tests.
5 Sound power level.
6 100% workload at 50°C on base casting.
7 The term of the limited warranty may vary by region. Visit support.wdc.com/warranty for details.
