Hard Drive weight increasing?

Il ajutam si noi pe asta?

Apologies if this is the incorrect area for this question.
I’ve noticed that as I copy data/install programs on my Laptop, the weight of the Laptop increases. I have a bad back and am medically limited on the amount of weight I can carry so I need to be very carefull not to inflict injury upon myself.
I have also noticed my XBox feels heavier as well (the more games I save or purchase from arcade). I generally don’t travel with my XBox so that is not an issue for me, but note the I am having the same results.
My ask, what is the weight/file ratio? So for example, how many GB’s = 6oz? I dread the day I need a dolly to commute to work with my Laptop.
Thanks in advance!
