It's been a little over four years since I reviewed my first Synology product, the humble CubeStation CS407e, which supported 2TB of network storage using four 500GB hard drives at a cost of around $120 per drive. Back then I concluded that the CS407e was the best four-bay NAS device available. Over the last few years, we've also examined the DiskStation DS409+ and the budget-minded DS410j, both of which ranked favorably among the competition.Synology's portfolio has since grown to include hefty 5 to 12-bay devices, which we find intriguing having only reviewed one NAS beyond 4 bays, the 8-bay QNAP TS-809 Pro Turbo. At $1,700, the TS-809 Pro Turbo was, and still is the most expensive product QNAP makes with the exception of rack mount hardware. Considering we tested the TS-809 Pro Turbo over a year and a half ago, Synology has been slow to respond with a device that meets or exceeds the TS-809's storage capacity.
