Synology FlashStation FS6400 24 Bays NAS Storage

Synology FlashStation FS6400 24 Bays NAS Storage Price in Bangladesh.

The Synology FlashStation FS6400 is a high-end, all-flash rack-mount NAS system built specifically for latency-sensitive, high-throughput workloads such as enterprise virtualisation, database operations, online transaction processing, multimedia post-production and other I/O-intensive applications. Engineered in a compact 2U form-factor with 24 hot-swappable 2.5″ drive bays, it supports SAS/SATA SSD devices and can scale further with Synology expansion units, making it ideal when space is at a premium but performance demands are high. 

Under the hood, the FS6400 is powered by dual Intel® Xeon® Silver processors, large amounts of DDR4 ECC memory (expandable up to 512 GB), dual 10 GbE ports (and optional higher-speed network cards), and hardware-designed optimisations for SSD wear-leveling, RAID F1 and low latency.  It runs Synology’s mature DiskStation Manager (DSM) OS, offering enterprise-grade features such as Btrfs filesystem with built-in data-integrity tools, snapshot replication, iSCSI support and a full cloud-capable app ecosystem. 

For organisations looking for a future-proof, high-density, flash-optimised storage solution that bridges private-cloud, virtualisation, file-services and archival workflows, the FS6400 delivers compelling value in a refined enterprise-grade chassis.

✅ Key Features

• 24 Hot-Swappable 2.5″ Drive Bays: Supports SAS/SATA SSDs in all 24 bays, enabling high-density flash deployment for ultra-fast storage.

• Dual Intel Xeon Silver CPUs: Delivers multi-core performance with NUMA optimisation for high-concurrency workloads. 

• Massive Memory Capacity: Ships with 32 GB DDR4 ECC (in typical inference) but supports up to 512 GB for heavy caching, virtualisation and in-memory processing. 

• High Network Throughput: Two 10 GbE ports out of the box, with PCIe slots available for 25/40 GbE add-in cards for network-bound workloads. 

• Enterprise File System & Data Protection: Supports Btrfs with file-/folder-level snapshots, file self-healing and advanced RAID modes including RAID F1 (flash-specific algorithm). 

• Expandable Storage: Optionally connected to expansion units (e.g., up to 72 drives total) to scale capacity without replacing the main unit. 

• 2U Rack Form Factor: High density for data centres, with hot-swappable drives, redundant PSU design and enterprise-ready cooling. 

✅ Why Buy This Product

If you need storage that goes beyond typical NAS capabilities—where thousands of IOPS and ultra-low latency are required—this unit is made for those demands. The FS6400 offers enormous headroom: flash-only bays to support high-performance services, vast memory to support caching, large network bandwidth to avoid bottlenecks, and enterprise software to protect your data. For businesses running virtual machines, databases, high-resolution media workflows or large-scale file services, the cost is justified by the performance and longevity.

Moreover, Synology’s DSM software provides an ecosystem that combines storage, backup, file-sharing, sync and virtualisation—all built in, reducing the need for multiple separate appliances. The ability to expand drives and network capacity means you’re investing in a system that can grow with your business. For mission-critical environments where downtime is unacceptable, features like RAID F1, file-healing and snapshots deliver important peace of mind.
