How much does a terrabyte weigh

[Paul-R]

A terrabyte weighs about 80% of the length of a dollar.

a Terrabyte equals energy and thus it must also equal mass if stored on a chip or disk, do you agree and if so how much would it weigh, and if so could we accurately weigh things to see how much information they contain?

Is it weighed on the earth,moon or other planet? If its in free space its no longer a weight but just a force. 2 masses of the same size doesnt mean they would weigh the same. Without a gravitational force there is no weight. If its weighed on earth you have the problem of a changing gravitational force due to the Sun and moon. You could only estimate its weight at any given time. So no you couldnt weigh things accurately to see how much information they contained.

Over the past decades, mass required to store X amount of data has obviously dropped. I still remember wasting a year's work on a computer, now outpaced by a free cell phone, on all parameters.
It's easy enough to bring the density of information down. Just put a micro SD card in a balloon, and then further fill the latter with helion. But then you increase the volume per byte, which can bug us in other ways.
I bet that a sensitive enough scale could detact weight anomilies on emptied and full harddisc, but I wonder whether the information itself would be causing it :-)

I think photons are measured in pressure rather than weight, because photons have pressure but have no mass.
