What can you do with usb stick for storage?
How many-gigabite routeros supported?
Can you print the logfile?
Thanks for answer
Hello
you can save dude data , webproxy-cache , usermanager data to usb storage.
i test RB751uHnD usb port and connect my WD 1TB hard disk and my router detect it!
but i do not format it because i need my data 
for printing log i think best way is sending log to a Syslog server like kiwi or dude or solarwinds or mikrotik syslog!
Thanks, for reply i want do a koppel of experiments with this.
