10 Reasons why SharePoint is not a File Server

sharepoint file server

Many companies are migrating to Office 365.   SharePoint Online is included with most subscriptions for free. Often, IT professionals are asked to evaluate moving their company file servers to SharePoint Online.  While SharePoint is great for collaborating on documents with teams inside or outside of the company, can it completely replace an on-premise file server for larger firms?

Here’s the list of the top 10 reasons we compiled on why SharePoint is not a file file server:


  1. Speed – Nothing can beat the speed of local network file server access. While Internet speeds are measured in Megabits, local network speeds are measured in Megabytes.  A local network connection is at least 10 times faster than any Internet connection.  For example, a fast 100 Mbp/s home Internet connection only equates to 12.2 MB/S.   In the office, networks are typically 1GB – a whopping 125 MB/s!!  For large files access, nothing beats a local area network connection.


  1. Simplicity – Users are trained to easily grab their files from a mapped drive. With SharePoint, files are stored in libraries that are accessed using a web-based interface. The interface looks nothing like Windows File Explorer.  Alternatively user can access file using the OneDrive for Business client which requires user training and  intervention to sync and to locate the shares they need.


  1. Storage Capacities – Even the smallest companies have easily terabytes of data. SharePoint Online has a 1TB limit on each library, a  5000 item display limit, a 15GB file size limit and a maximum 100,000 file sync limit.   Even if you did store this much data, or files this large, accessing them over the Internet may be unworkable (see Reason #1).
