Synology FS3600 24 Bay FlashStation - Diskless Enterprise NAS

Name: Synology FS3600 24 Bay FlashStation - Diskless Enterprise NAS
Brand: Synology
SKU: FS3600

Overview

The Synology FlashStation FS3600 is a 24-bay all-flash network attached storage server engineered for enterprise environments where I/O performance is critical. Built around a diskless chassis that accepts 2.5-inch SSDs, it delivers over 193,000 iSCSI 4K random write IOPS — making it suitable for databases, virtualization hosts, VDI deployments, and other latency-sensitive applications. The unit ships with 16 GB of DDR4 memory and runs Synology's DiskStation Manager (DSM) operating system, which provides a comprehensive suite of storage management, backup, replication, and monitoring tools through a web-based interface.

A standout feature is Synology's proprietary RAID F1 technology, which addresses a fundamental risk in all-flash RAID arrays: because identical SSDs under identical workloads tend to wear out at the same rate, traditional RAID configurations face the possibility of multiple simultaneous drive failures. RAID F1 mitigates this by deliberately distributing write operations unevenly, designating one drive to absorb more wear so that drives reach end-of-life at staggered intervals. For capacity growth, the FS3600 scales to 72 drives via expansion units, supporting over 500 TB of raw flash storage. Snapshot Replication provides rapid point-in-time recovery to minimize downtime, and native integration with VMware, Hyper-V, and Citrix environments comes at no additional licensing cost.

Pros & Cons

👍 Pros

Over 193,000 iSCSI 4K random write IOPS provides exceptional performance for I/O-intensive applications
Scalable from 24 to 72 drive bays via expansion units, supporting over 500 TB of all-flash capacity
Synology RAID F1 technology prevents simultaneous SSD failure by distributing write wear unevenly across drives
Snapshot Replication enables fast data protection and low RTO recovery without third-party backup software
Built-in virtualization support for VMware, Hyper-V, and Citrix with no additional licensing fees

👎 Cons

Sold diskless, so the cost of populating 24 bays with enterprise SSDs adds significantly to total investment
16 GB of base memory may need upgrading for heavily virtualized or multi-application environments
Enterprise-grade pricing and feature set far exceeds the needs of small businesses or home users
Requires expansion units sold separately to reach the maximum 72-bay, 500+ TB configuration
Physical size and power requirements demand proper rack infrastructure and cooling

Frequently Asked Questions

Does the FS3600 come with drives installed?

No. The FS3600 is sold diskless — you purchase and install your own 2.5-inch SSDs, which allows you to choose drives that match your capacity and performance requirements.

How much storage capacity can the FS3600 support?

The base unit holds 24 x 2.5-inch drives, and with expansion units it scales up to 72 drives for over 500 TB of raw flash storage.

What is Synology RAID F1 and why does it matter for all-flash storage?

RAID F1 is Synology's proprietary RAID level designed specifically for SSDs. It distributes write operations unevenly across drives so that one drive absorbs more wear than others, preventing the scenario where all SSDs reach end-of-life simultaneously — a real risk with traditional RAID on identical SSDs.

Does the FS3600 support virtualization environments?

Yes. It integrates with mainstream virtualization platforms including VMware, Hyper-V, and Citrix at no additional licensing cost, supporting iSCSI, NFS, and SMB protocols.

What operating system does the FS3600 run?

It runs Synology DiskStation Manager (DSM), Synology's Linux-based operating system that provides storage management, data protection, and application services through a web-based interface.
