Hexus posted a review on the Synology DS1515
A quote from the article:
Synology is fleshing out its range of SMB NAS solutions with the launch of the DS1515. Priced at £498, this five-bay unit is the latest addition to the company's Value Series range and touts a quad-core CPU, hardware encryption engine and four Gigabit Ethernet ports.Synology DS1515 Review @ Hexus
Designed as a "cost-effective storage solution for growing businesses," the DS1515 undercuts the existing DS1515+ (£640) by juggling its internal hardware. Whereas the + model is outfitted with an Intel Atom processor and expandable memory, the streamlined DS1515 carries an ARM-based processor from little-known Israeli chip manufacturer, Annapurna Labs.
