MongoDB: Bulk insert (Bulk.insert) vs insert multiple (insert([...])) : <p>Is there any difference between a <a href="https://docs.mongodb.org/manual/core/bulk-write-operations/" rel="noreferrer">bulk insert</a> vs <a href="https://docs.mongodb.org/manual/reference/method/db.collection.insert/" rel="noreferrer">inserting multiple documents</a>? </p>

<pre><code>var bulk = db.items.initializeUnorderedBulkOp();
bulk.insert( { item: "abc123", defaultQty: 100, status: "A", points: 100 } );
bulk.insert( { item: "ijk123", defaultQty: 200, status: "A", points: 200 } );
bulk.insert( { item: "mop123", defaultQty: 0, status: "P", points: 0 } );
bulk.execute();
</code></pre>

<p>VS</p>

<pre><code>db.collection.insert(
   &lt;document or array of documents&gt;
)
</code></pre>

<p>Is there one thats faster? </p>
