You shouldn't have any problems. Read about tunefs if you wish, it may
help you.
I have a 6x250gb array (1.25tb RAID5). FBSD 5.2.1 refused to support a
filesystem larger than 1.0tb, so i chunked it into 2 partitions to get
around that problem and then I mounted them back using mount_nullfs so
it appears as though all dirs are on the same partition in a single
directory. Not sure if the 1TB filesystem limit problem is unique to me
or not, but you will be fine with your .75tb no question.
