Makes sense.

I'ld be unable to add another physical hard drive to the machine. I
could barely afford it with one drive!

Well, I'll be using the machine for piloting interstellar craft while
recreating 3D renditions of their environment every 1/1000000 second,
a nessecity as they travel at .98 C. Well, maybe not, so I guess that
I could pass on the fine tuning :)
