Overview

The Synology FS3410 is a 2U, 24-bay all-flash NAS engineered around one premise: removing storage latency from environments where spinning disks or hybrid arrays can no longer keep pace. Its headline figure — 356,500 iSCSI 4K random read IOPS and 129,400 write IOPS — isn't marketing abstraction. At 4K block size, those numbers represent the granular, high-frequency access pattern that virtualised workloads, database transaction logs, and containerized services generate continuously. A system that saturates at 50,000 IOPS under concurrent VM load becomes an invisible ceiling on application performance; the FS3410's architecture is designed to ensure that ceiling sits well above what even dense deployments will reach.

Built-in Gigabit and 10GbE ports cover the connectivity needs of most enterprise deployments immediately, with 25GbE and 40GbE available via expansion NICs for fabric-attached or high-throughput workflows. High-availability is addressed both at the hardware level (redundant PSUs and failover architecture) and through DSM's software stack, which supports VMware vSphere, Microsoft Hyper-V, Citrix XenServer, OpenStack, and Kubernetes CSI — meaning it integrates into nearly any existing virtualization or container orchestration environment without requiring a platform redesign. The FS3410 is the right tool for IT teams running latency-sensitive databases, VDI pools, or high-density VM clusters who need storage that genuinely keeps up with compute.

Pros & Cons

👍 Pros

  • Over 356,500 iSCSI 4K random read IOPS eliminates storage as the bottleneck in dense virtualized environments.
  • 24 x 2.5" SSD bays provide massive all-flash capacity headroom for growing datasets.
  • Native Kubernetes CSI driver support alongside VMware, Hyper-V, and Citrix certification covers the full enterprise virtualization stack.
  • Built-in 10GbE ports allow immediate deployment without additional NIC investment for most workloads.
  • 5-year limited warranty is competitive for enterprise-class storage hardware.

👎 Cons

  • Ships diskless — drive costs are entirely separate and enterprise SSDs at this scale represent a very significant additional investment.
  • 25GbE and 40GbE networking requires purchasing additional Synology NICs, adding cost and configuration complexity.
  • 24-bay 2U all-flash form factor and power draw are enterprise-tier; this unit is not appropriate for small offices or budget-constrained deployments.
  • Management and configuration depth of DSM requires administrator familiarity with Synology's ecosystem to realize full performance potential.

Frequently Asked Questions

Diskless means no SSDs are included — you supply your own 2.5" drives. Synology publishes a compatibility list for the FS3410; you'll want enterprise-grade U.2 or SATA/SAS SSDs rated for sustained mixed read/write workloads. Consumer SSDs are not recommended — the controller is tuned for drives with higher endurance ratings.
At 4K block size over iSCSI, the FS3410 can service over 356,500 random read operations per second. For virtualized environments, that translates to dozens of VMs performing simultaneous disk operations without queuing — a bottleneck that plagues spinning-disk and hybrid NAS units at scale.
The FS3410 ships with built-in Gigabit and 10GbE ports. Upgrading to 25GbE or 40GbE requires adding compatible Synology network interface cards (NICs) to the expansion slots — these are not included and represent an additional hardware cost.
Yes. Synology includes a Kubernetes CSI (Container Storage Interface) driver, allowing the FS3410 to serve as persistent block storage for containerized applications. This is in addition to its certified support for VMware vSphere, Hyper-V, and Citrix XenServer.
Synology backs the FS3410 with a 5-year limited warranty, which is standard for enterprise NAS hardware in this class and covers manufacturing defects in the unit itself — not the drives you install.
