Hi, I'm working In IT Department in Medium company that contains 4 departments which each department have 4-5 computer , In one department will have one PC hold all data and shared among department, Now I want to implement NAS in this office, can NAS do Virtually by department to access the file ? And Is it NAS easy to get infected by Virus from the PC if sharing file?
Please recommend which NAS suitable for my company. Thank You.

I wonder between Synology and Qnap which is better in term of functionality and techonlogy? And is there any NAS that support SMS system when plug in GSM modem?

Thanks, I already get DS210j from you, now try to do dyndns. try to figure it out, already created account, but cant still access internally.
