Hot Swap Bays
The ARS-3031 was designed systematically and hosts four 3.5" SATA hard drives in the front part of the system. All of these are installed using aluminum frames. However, their locking mechanisms do not protect the drives from being removed accidentally (see image above), so you should mount the front cover whenever you do not need to access the drives. The front part of the appliance will also host a battery of LEDs that show drive status and activity.
