So 2014 best storage of NAB award goes to the G Speed Studio They were able to store 24TB with a 660MB transfer rate. The G Speed comes with thunderbolt two connection cables which gives it quick and easy compatible access with daisy chain devises and mac computers. It also comes with a 3 year warranty so if you happen to fill the storage.
This would be useful if I happened to be a producer that was making a lot of videos and need an extra place to store all of it. I could use this if I wanted to make sure all my projects would be backed up on a third party device which is extremely helpful during hard drive crashes.
