What counts are the flows you have, not the bandwidth. Here are some numbers of our university uplink, to give you a feeling:
Flows: ~50k/s in, the same out Packets: ~1Mp/s in, the same out Bits: typically 10-20 Gbit/s in, ~5Gbits/ out This gives me ~500GByte/d But remember: the used disk space depends only on the number of flows.
