Synology's latest single bay NAS is based on the twin-bay DS215j and uses the same processor, memory and configuration of ports and connectors. For some reason Synology has seen fit to change the colour from white to black, perhaps to disguise the heritage of the DS115 tiddler, but that strikes us as a curious move. The DS215j is a fine performer thanks to its dual core 800MHz Marvell CPU and 512MB of DDR3 memory is more than adequate for a small NAS.
