Synology® Announces DiskStation DS925+ and DX525 Expansion Unit

BELLEVUE, WA—4 June 2025—Synology today launched DiskStation DS925+, a powerful and reliable storage solution designed for creative professionals, tech enthusiasts, and home users with growing data needs.

"The 4-bay Plus Series models inherited over one million installations, and have always been among our most widely-adopted products." said Jeffrey Huang, product manager of Synology. "Not only are they favored by professionals, but also deployed by enterprises in remote and branch environments as edge servers. For this reason, we've designed the DS925+ to deliver business-grade performance and reliability."

Compact, Powerful, and Ready to Grow with You

The Synology DS925+ is a high-performance data storage solution designed to handle everything from personal backups to demanding media libraries – all in a space saving design. Equipped with dual 2.5GbE ports and two M.2 slots for creating all-flash storage pool or cache, the DS925+ delivers substantial performance gains with preconfigured settings compared to its predecessor—including 149% faster SMB downloads, 150% faster uploads, 131% faster reads, and 150% faster writes – perfect for your small business, home office, family photos, video collections, device backups, and more.

Whether you're a content creator, small business owner, or simply in need of more space for your growing digital life, the DS925+ also provides high capacity and scalability. When paired with the new DX525 expansion unit, it supports up to nine drive bays and offers up to 180 TB of raw capacity.

The DS925+ is optimized for use with the Synology Plus Series hard drives, delivering long-term performance and reliability. The Plus Series hard drives undergo over 7,000 hours of testing to ensure they meet rigorous performance standards for reliable data storage. For optimal integration and long-term dependability, DiskStation Manager (DSM) on the DS925+ requires compatible hard drives for installation that follow a carefully curated drive compatibility framework.¹
