The MobileSTOR MS2UTN+ comes carefully packaged in soft foam cushion supports and a separate accessory box for the cables. Included with the device are power, USB and eSATA cables, internal SATA to eSATA PCI bracket, keys to access the trays as well as screws to mount the drives, a quick setup guide and software CD.
The front of the device contains the two drive trays stacked horizontally at the bottom of the housing. Above this are three LEDs to indicate power, temperature warning and alert/error as well as a mute button to silence the audible alarm in the event one occurs. At the rear we find an IEC320 C13 receptacle which is nice, since you can use any standard PC power cord, rather than having to deal with an external power brick. There is an on/off switch and 40mm exhaust fan as well as eSATA and USB 2.0 ports. At the bottom is a small RAID type selector dial with seven positions and reset button to reboot the device after making a change.
To access either of the drive trays, insert the end of the key, or any other small pointy object, into the lock hole on the front. This releases the hinged latch arm which then can be opened fully and the tray pulled out, similar to many other hot-swap server hard drive configurations. The front center of the tray is vented to allow cool intake air to enter here and be drawn across the body of the drive before being exhausted out the rear of the housing.
The trays slide on plastic rails which align the drives with the SATA connectors inside at the rear. Unlike IDE drives, SATA and SATA-II drives utilize hot-swap capable connections for both data and power, allowing you to pull drives for replacement without shutting off power to the device first. Depending on the array type used, removing a drive while the disk volume is in use can result in data loss, so this is really only a great benefit for RAID1 mirror configurations where the other duplicate drive can continue read/write operations.
Continue ahead to installation and testing.
