A personal cloud space My boss has a long lasting problem, he has an annoyance about distributing the research materials for group members. The smartest way is to apply a online space to store the materials, for example dropbox, google drive or onedrive, but the disadvantage of those online space is the space is too small. Recently I notice a convenient, and maybe suitable product for us. The technical name for that product is network attached storage, maybe I can call it as personal online space. The space of network attached storage is limited by the installed hard disk, so the space can easily be pushed to few Terabytes. Now we installed a network attached storage in our laboratory, and we hope it can actually deal with my boss' annoyance.
