The all-flash FS1018 supports up to 12 x 2.5" SATA SSDs in a desktop form factor. It is low latency and provides high IOPS for the demanding work environments. It is ideal for running business applications like mail services, virtualization and latency-sensitive applications.

Supercharge your storage with speedy performance

With four built-in Gigabit LAN ports, FS1018 is capable of performing Link Aggregation and failover. For environments requiring a higher speed, the addition of an Ethernet add-on card can increase data transmission to 10GbE.


Due to the peculiarities of SSD and RAID technology, a common challenge lies in how to prevent all of the drives from failing at the same time because of the evenly distributed workload. RAID F1 alleviates this problem with a specially designed algorithm to unevenly distribute workload to drives, enhancing the resilience of the storage pool and ensuring your data remains safe.

Next-generation file system for advanced data protection

The Btrfs file system introduces the most advanced storage technologies. It helps to prevent data corruption and reduce maintenance overhead with optimized snapshots. Btrfs ensures high-level data integrity, while taking advantage of flexible and efficient data protection and recovery tools.


Synology FlashStation FS1018 is a high-performance, desktop form factor NAS specifically designed for 2.5" SATA SSDs. FS1018 is ideal for running business applications, including data backup, virtualization, mail services, and services that require low-latency. Synology FS1018 is backed by Synology's 5-year limited warranty. AC Input Power Voltage - 100V to 240V AC.
