A 512G CineMag will unpack to approximately 800G of memory upon downloading. Using Gigabit Ethernet, a full CineMag can take 5-7 hours to download, depending on the connected computer and hard drive capabilities. With the 10-Gigabit Ethernet option, this time can be shortened to less than one hour, again depending on computer and hard drive speeds. Note that a full 512G CineMag holds 132 minutes of 1920x1080 or 32 minutes of 4K material (both played back at 24fps), meaning the 10GE option is close to or even significantly faster than real time playback.
