Hi Guys,

I want to apologize in case I am offtopic, but I been struggling lately to make decisions and find the best option for a storage system for my company, we been super small till 2 years ago … but in the last two years, business exploded and we end up with offices on 4 different continents. now the biggest issue is file sharing…. we do currently using Google Drive … but it’s just not enough anymore… What would you guys suggest as the next step? Thank you in advance for all your sugestions
