The following table gives a description of the supported raster formats and their extensions and identifies if they are read-only or if they can also be written by ArcGIS. The geodatabase is the native data model in ArcGIS for storing geographic information, including raster datasets and raster catalogs however, there are many file formats you can work with that are maintained outside a geodatabase.
