Without drives installed, the TS-412 weighs 6.61lbs (3.0kg), a bit heavier than the Synology DS411J.
The black front and aluminum chassis gives it a very sleek and professional look.
Like all good NAS devices, the TS-412 allows drives to be hot-swapped during operation.

The use of individual, detachable 3.5-inch hard drive trays makes adding or removing storage capacity a breeze.
The security-conscious should know that the bays can’t be locked so drives can be removed at any time.
However, we can assure you that this particular feature is not present.
