Re: Confused - gigabit ethernet speed & Superhub

Cat5 cable supports gigabit speeds fine, 5e is only required if you have very poor quality cable.

In either case if it connects at gigabit it will run at gigabit, and you'll get >950mbps throughput even with overheads.

The problem is more likely a combination of latency and other bottlenecks, though most NAS devices can do about ~200-400mbps and most hard drives can do way more. The WD5000AAKS for example does around 800-900mbps.

I would suggest testing network bandwidth on it's own (i.e. isolating it from the NAS/file transfer aspect) as well as keeping an eye on latency while doing a transfer test.
