Mongoose: what's the differences between Model.create and Collection.insert

In Mongoose, there is Model.create and Collection.insert (the latter isn't strictly part of Mongoose, but of the underlying MongoDB driver).

According to the Mongoose developer, they are basically the same when called with an array of documents, although looking at the code makes me think that there are subtle differences (warning: I haven't looked at the code that well so I might be mistaken about the following):

  • using Model.create will call any validators/hooks declared on your schema;
  • Model.create does a .save for each document in the array, resulting in N database calls (where N is the number of documents in the array); Collection.insert performs one large database call;
