The ability of iSCSI to support high throughput depends on:

1Gbps ethernet can handle up to 115MB/s per interface. Using MPIO round-robin over several interfaces you can continue to add throughput if the application can scale well across these multiple paths.

hey this part is fascinating, -so how would one practically deploy this, -say 4 GB NICs and some supported hardware? for traffic 100 - 200 megs daily perhaps this is too much?
There's no such thing as 'too fast', but do you really need to complete you daily transfer in less than a second? On the practical side the underlying disks aren't going to be that fast anyway.
On the storage side, not sure if MPIO will auto-detect the device, but maybe it'll see it. -wonder if Vsftpd would play well with all of this.
If you put a filesystem on an iscsi target and mount it, vsftpd won't know/care about the actual device type.
