A SATAII hard disk could easily saturate a 400Mbps link (if both ran at theoretical maximums, neither will).

With 200Mbps adaptors getting 'real world' performance of around 30-40Mbps, a 100Mbit ethernet adaptor would be plenty. Going on those numbers, 400Mbps adaptors would probably be fine with a 100Mbps NIC as well - with a real world performance of around 60-80Mbps (probably).
RE: sampler & Barry
Sampler
400Mbps = 400,000,000 bits per second
300MB/s = 8*300,000,000 bits per second
= 2,400,000,000 bits per second
