Synology Expands All-Flash Enterprise Storage Lineup

On May 7, 2026, Synology unveiled its latest additions to its storage solutions, announcing the release of two all-flash storage systems – the FS6420 and FS3420. Targeted at enterprises that demand low-latency performance, these systems are designed specifically for rigorous workloads including on-premises virtualization, databases, and enterprise applications.

Jeffrey Huang, Product Manager at Synology, emphasized the growing need for robust storage solutions in today's business landscape: "More organizations are operating demanding on-premises workloads than ever before, necessitating storage that can keep pace. The FS6420 and FS3420 significantly improve IOPS performance and latency-sensitive workloads compared to previous models. They are ideal for mid to large-sized enterprises or co-location environments looking to deploy enterprise applications or virtualization workloads."

Enhanced Enterprise Performance and Proven Reliability

The FS6420 and FS3420 are robust 24-bay, 2U rack-mounted systems that provide remarkable I/O responsiveness and enhanced performance compared to their predecessors. Notably, the FS6420 achieves over 929,000 IOPS for read operations and 257,000 IOPS for writes, demonstrating increases of 40% and 26% respectively. The FS3420 similarly excels with more than 478,000 IOPS for reads and 169,000 IOPS for writes, showcasing improvements of 21% and 32% in read and write performance. Both models also exhibit more than 60% improvement in SMB read throughput, making them optimal for high-bandwidth file sharing.

Beyond just speed, these systems offer flexible connectivity options. They come standard with dual 10GbE ports, with optional integration for 25GbE or Fibre Channel adapters for seamless compatibility with high-speed network infrastructures.

Reliability is a core design principle in both units. They feature redundant power supplies to eliminate single points of failure. The integrated 10GbE network supports failover and load balancing, ensuring continuous uptime. Additionally, the out-of-band management capability allows administrators to troubleshoot remotely and access system logs even when the server is powered down.

Built for High-Demand Workloads

Equipped with Synology DiskStation Manager (DSM), the FS6420 and FS3420 bring the full functionality of Synology's software ecosystem to enterprise environments. This includes:

Wide Platform Compatibility

Both systems are certified for use in VMware® vSphere®, Microsoft® Hyper-V®, Citrix®, and OpenStack environments, expanding their versatility.

Robust Workflow Support

Their combination of high-speed networking and all-flash performance enables these systems to handle data and network-intensive workloads. They are particularly well-suited for projects that require multiple users to access large files via SMB or NFS, such as video post-production or large-scale CAD projects.

Intelligent Storage Tiering

Synology Tiering maximizes storage efficiency by managing data across performance and capacity tiers. The FS6420 and FS3420 act as high-performing hot tiers, ensuring sufficient flash capacity and IOPS headroom for critical workloads.

Built-In Data Protection

Using Active Backup for Business, unlimited virtual machines can be backed up from physical servers, complemented by Snapshot Replication for immediate recovery points and granular restoration at the volume, folder, and file level, effectively meeting RPO and RTO goals.

Availability

The FS6420 and FS3420 will be available globally through Synology’s partner and distributor networks starting from May 7, 2026. For further details, visit the product pages for FS6420 and FS3420.
