As someone with a very rudimentary understanding of biology, how much data are we talking about in terms of a DNA sequence? I.E. if we wanted to store a human's complete set of DNA digitally, are we at a point where we can definitively say "this will take X GB of storage"?

A complete haploid human genome is 3 billion base pairs. One byte encodes four basepairs, so that's 750MB in total; and it losslessly compresses to less than half that amount.
If you store more than one genome, any additional genome is only 4MB because human genomes are 99% identical.
So you could store the genomes of an entire city on your hard drive.

From elsewhere on the internet (https://stackoverflow.com/questions/8954571/how-much-storage...):
"The 2.9 billion base pairs of the haploid human genome correspond to a maximum of about 725 megabytes of data, since every base pair can be coded by 2 bits. Since individual genomes vary by less than 1% from each other, they can be losslessly compressed to roughly 4 megabytes."
