you say limit ?

here is what i saw / read

server on 10mbit unmetered cannot push more than 4 tb A month
100mbit shared can push around 12tb
100mbit unshared can push around 40tb

upto space it depends upon hard disk they got installed as far i saw / read i see max 1.5tb a disk and max 12 disk per server

i hope my information is correct
