Hold it! You should know better than that! Here's the binary-SI prefixes for computers kilo- k (2^10)^1 = 2^10 = 1024 mega- M (2^10)^2 = 2^20 = 1048576 giga- G (2^10)^3 = 2^30 = 1073741824 tera- T (2^10)^4 = 2^40 = 109951162778 peta- P (2^10)^5 = 2^50 ~= 1.1259e15 exa- E (2^10)^6 = 2^60 ~= 1.1529e18 So, 64 bits will address precisely 16 exabytes.
