if dili Intel based gigabit NIC ang gamiton, ang transfer rate nya naa ra sa 40 ~ 60 MB/sec... if intel based NIC, mo abot ug 80 ~ 100+ MB/sec... mao ni akoang experience on an 8 GB and 4 GB memory FreeNAS servers... using different type of NIC chip sets...
nice to have ra man hinoon nang 80 ~ 100+ MB/sec transfer speed... need lang ni kun mag back-up ta's entire HDD system to another server...
mao ni na gigabit NIC chip sets diay ang akoang nasuwayan sa FreeNAS OS...
