Once connected, you can take advantage of the HFS+ or APFS file system for use with Mac computers and the NTFS file system for use with Windows computers. Additionally, you can see the status of the Drobo as represented by the drive bay indicator lights, the capacity gauge, and status lights to ensure your Drobo is functioning properly.
This Drobo storage array comes compatible with Apple Time Machine allowing you to create complete system backups directly from your Apple computer. You can even allocate a specific amount of data you wish to use for each system backup. Additionally, the included Drobo Dashboard software provides an intuitive user interface to manage all aspects of your Drobo from monitoring the status of the drives, to administrative tasks, and more.
