Has anyone pushed the 2.5 Gigabit NIC in the HL8?

I am looking into purchasing a HL8 eventually, to replace another server I have.

I have a Windows PC with a 2.5 Gigabit adapter and an External HDD containing a lot of data for the new server. (Running USB3)

I was wondering if anyone has really pushed the 2.5 Gigabit NIC in the HL8 with data transfers?

I will have a 2.5 gigabit switch between both systems.
