FlashStation FS6400

Performance and Processing

Powered by dual Intel Xeon Silver 4110 8-core processors (2.1 GHz, up to 3.0 GHz Turbo), the FS6400 delivers over 240,000 iSCSI 4K random write IOPS for low-latency tasks. It supports 32GB DDR4 ECC RDIMM (expandable to 512GB) for robust multitasking. Users praise its performance for virtualization and databases but note high power consumption (~300W). Ideal for multimedia, VMs, and transaction processing.

Storage and Scalability

Features 24x 2.5" SAS/SATA SSD bays (drives sold separately), supporting RAID 0, 1, 5, 6, 10, F1, and JBOD. Flash volume deduplication on Synology SSDs achieves a 3.15:1 data reduction ratio. Expandable with two RX1222sas or FX2421 units for up to 72 drives. Users value the scalability but note SSD costs add up. Btrfs file system enhances data integrity. Perfect for enterprise storage.

Connectivity and Features

Includes 2x 10GbE, 2x 1GbE, 2x USB 3.2 Gen 1, and 2x PCIe 3.0 slots for optional Ethernet cards (25GbE/40GbE). Supports Link Aggregation and failover. Certified for VMware vSphere, Microsoft Hyper-V, Citrix XenServer, and OpenStack. Features AES-256 encryption, Virtual Machine Manager, and Synology DSM OS. Users appreciate connectivity but note rail kit sold separately. Ideal for virtualization and high-speed networks.
