120 Gigabytes, but probably only 115 Gibibytes

Tired of trying to figure out if a GB is 10^9 bytes, 2^30 bytes, or some combination thereof? Well, help resolve the confusion by using the right words for the binary versions.

giga = 10^9; gibi = 2^30
mega = 10^6; mebi = 2^20
kilo = 10^3; kibi = 2^10

(Oh and the headline? That's the size of the new harddrive I'm installing this weekend)
