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, megabit per second (Mb/s) = one million bits per second, and gigabit per second (Gb/s) = one billion bits per second.

The thing is that we've been told that WD black was the thing. We were told that for years. But I did my research and the WD red is actually your best option. This is the most reliable drives that WD makes, so don't buy anything else than reds, unless you really need to save 10$, buy a blue. (Read More)
