XBOX additional memory

[chrismcg1]

OK - first of all I am an idiot- have been waiting ages for GTA v - get it today and it needs 8gb memory. I then remember after my last RROD I bought a 4gb Xbox - DOH! Basically, will this resolve my problem - http://www.amazon.co.uk/gp/cart/view.html/ref=gno_...
If that doesn't work its a Kingston DataTraveler 16Gb 101 G2 USB DT101G2/16Gb - plug it in and additional memory space? HELP!

Any advice greatly appreciated.
