title: Would containing NSData in a different Core Data entity make retrieval of the original entity faster?
body: <p>So here's my example. I have an entity called Photo. It has the attributes of 'width' and 'height', for easy retrieval, and a NSDate of when it was taken. It also has an NSData of the photo itself. If i moved this NSData to an attribute with a one-to-one relationship to Photo, would it increase saving speed if I changed another attribute in Photo, or fetching speed if i fetched another attribute in Photo?</p>
