Synology FlashStation FS3420 - NAS, Black

The Synology FlashStation FS3420 is a 2U, 24-bay rackmount all-flash NAS designed for enterprise environments that require low-latency storage. It features 24 hot-swappable drive bays for 2.5-inch SATA III SSDs. An eight-core, sixteen-thread Intel Xeon D-1739 processor—with a 3 GHz base frequency—provides the necessary compute power. The unit comes with 32 GB of DDR4 ECC RDIMM, which is expandable to 192 GB as workload requirements grow. The system supports various RAID configurations, including RAID F1, which helps prevent multiple SSDs from failing simultaneously. It supports network protocols such as iSCSI and SMB for integration into existing virtualization and file-sharing environments.

The chassis measures 482 mm by 88 mm by 724 mm. Two integrated 10GbE RJ45 ports provide connectivity and support transfer speeds up to 10,000 Mbit/s. Two PCIe Gen 3 x8 slots are available for additional network cards or storage controllers. Four 80 mm fans provide active cooling, while an internal 550 W power supply powers the 24-bay array. The DiskStation Manager (DSM) operating system handles storage volumes and includes built-in tools for data protection, such as snapshots and AES encryption. This model is suited for enterprise applications that require predictable performance and high IOPS.

• 3.5 GHz boost frequency: provides extra processing power during peak workloads.
• ECC memory: detects and corrects errors to prevent system crashes and data corruption.
• Wake-on-LAN: enables remote system startup via network signals for better energy management.
• Broad file system support: compatible with BTRFS, NTFS, FAT32, and HFS+.
• 550 W internal power supply: supports a fully populated drive array and dual PCIe expansion.
• System logs: record operational events to simplify troubleshooting and maintenance audits.
• Two USB 3.2 Gen 1 ports: allow for direct connection of external hardware for data migration.
