With over 13 million devices sold, there's no question that Synology is the biggest manufacturer of NAS systems globally. But this category has changed quite significantly in the last 15 months; UGREEN made its grand debut with the introduction of the DXP4800 Plus and DXP2800, delivering sturdy designs with terrific hardware.
TerraMaster and ASUSTOR also did a much better job last year, polishing their software and overhauling their product lines to deliver better differentiation. By contrast, Synology had a quiet year and a half, with the brand's older models — the DiskStation DS923+, DS224+, and DS723+ — doing most of the heavy lifting.
Thankfully, that's changing with the debut of the DiskStation DS925+. The successor to the best-selling DS923+ shares the same design, but it comes with dual 2.5 Gigabit Ethernet ports as standard, and it has upgraded internals thanks to a quad-core Ryzen V1500B. It has four standard drive bays in addition to dual M.2 slots, and you can use SSDs to store data in addition to caching.
