Each DVD stores 9.2GB..(dual layer)
using that as a maximum, you can calculate your storage requirements.. lemme pull out my calculator...
9.2GB * 2200 = 20240 GB
Slightly over 20 terabytes should do it..
<LOL>
each terabyte is 1000 GB, so...
1000 / 9.2 =108.6...
so for each terabyte you add, you'll be able to store another 108 DVD's
keep in mind these are estimates.. if your going to use those sizes, you may want to set up a RAID array..
