for 5,3To 

	2GB * 5,3 = 10,6Go
	
	100MB/million inodes * 45 = 4,5Go

Total = 16Go Ram

i presume the number of inodes is the number of used inodes because the
number of inode on 5,3To is 5119 million.

The goal is to use a device of 15To with the same data, consider the
amount total of RAM at 45Go.

I will go to the store of the corner to buy RAM :)

Thanks
