I suggest a new rule of thumb: if the data can fit on a micro SD card [1], then it's smaller than a thumb, so it can't be big data. ;-)

My rule of thumb has been “if I could afford to put the data in RAM it’s not that big a deal”.

Also "If the data could fit on a laptop or desktop I can buy at a retail store"

Uh oh, a lot of ML startups just freaked out! Name brand 1TB microSDXC cards are less than $200 on Amazon.
