Most of us who run a network-attached storage device will realise that these devices will need to have constant power supply in order to keep the data safe. The common solution that we would take would be to connect the NAS’s AC power supply through an uninterruptible power supply. These devices have a built-in battery to provide enough power to allow for an orderly shutdown of the device or allow the device to run longer through a short outage.
Now Thecus have taken a cue from a common security-system design practice. This is where an alarm system has an integrated battery that is maintained by the system’s power supply. It is so that the alarm system can continue to protect the premises if there is a power outage.
They have extended this concept by providing an optional battery-backup module for the N4200 “muscle-NAS” unit as an alternative to a UPS setup, with the battery allowing enough power for an orderly shutdown or completion of firmware installation. This can also cater for power outages including situations where the device may be accidentally unplugged and may be enough for most home and small-business environments. If the NAS is used with an UPS, it could allow a larger safety margin for the data through the provision of “dual-layered” battery backup arrangement.
The concept may be worth it for equipment that is used in the home or by small businesses and would be a must for places where the power supply is likely to be unreliable. It also is another example where the manufacturers are racing to build the best example of a top-end network-attached storage device for the home or small business in a similar way to what Ford, GM and Chrysler were doing in the late 60s and early 70s with the “muscle cars”.
