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, megabit per second (Mb/s) = one million bits per second, and gigabit per second (Gb/s) = one billion bits per second.3 TB WESTERN DIGITAL HARD DRIVE CANVIAR GREEN READY FOR YOUR UPGRADE OR REPLACEMENT.IN STOCK READY TO SHIP OUT TODAY!!NOTICE:If you are not happy with a product for any reason, please contact us before leaving a neutral or negative feedback, we will do our best to resolve the problem for you.Thank you so much!!Shipping Method:It normally arrives in 01-06 days.
