I can speak from my own experience: in cases where workstations are switched every year or so, one drive makes it very simple to keep things synced, even for very large files. This is even true for large files (such as video or CAD files) that are enormous.
StatusPage is well suited for notifications on services and products. If you need to have a passive way to notify users, internal staff, or executives on the status of SaaS services, StatusPage is a low barrier way to do this with minimal setup and maintenance. StatusPage is not well suited for scenarios in which you want info kept private. If StatusPage is updated, the subscribers to those alerts will be notified so you just want to make sure you're addressing the right audience with updates.
I like Box better. If you sign into Microsoft using a personal account, be EXTREMELY careful. All of your downloads could suddenly be available to your entire company, and that is incredibly embarrassing. Did that happen to me? Not going to say, but just always check which MS account you sign into.
Using OneDrive is very intuitive and has been improved over the years. It's just like using native file management on either your Mac or PC. It's drag and drop functionality is easy and it clearly shows when files are uploaded to the cloud or if there are errors
It has a good performance, the pages load normally, access to the files, management, reports, everything is working well. With regard to integration with other systems, we have not done so yet.
It's a Microsoft product so there is a wealth of information online both from Microsoft directly and from millions of users but as a corporate user we also have access to direct Microsoft support through a variety of avenues (phone, email, etc.). This makes finding answers to issues more accessible, however, it does also mean that any new feature requests will get buried.
Support is very responsive although we haven't had to contact them in a time of emergency, all of our support inquiries were answered in a timely manner and usually resolved with their first response. Support responsiveness played a big role in our decision since if we need help during downtime, we can't really afford to wait.
Box is another file-sharing application that is very similar to OneDrive. Box falls short of OneDrive in its syncing capabilities. OneDrive is very quick with syncing so you never have to be concerned that you are not using the most up-to-date materials. Box was always a bit delayed and did not always accurately sync across systems. OneDrive benefits from being backed by Microsoft, so you expect the connection across applications that it allows. OneDrive also provides consistency for use and intuitive understanding because of that Microsoft consistency. I'd prefer OneDrive over Box.
I would say StatusPage on its own is a great service. StatusPage for Hipchat can only be used with that specific chat client. But on its own StatusPage can be integrated with many tools, like Slack, email notifications, text notifications, etc. I don't know of a tool that compares with StatusPage. You could essentially host your own status site with Greed Yellow or Red statuses, but you would be missing out on the robustness of a tool that keeps historical data, uptime, and segregates services based on components.
OneDrive allows us to save much time on creating and archiving backup copies of our data. Microsoft gives a guarantee on the possibility of recovery of files or folders even from 30 days ago. It provides a great comfort of work.
