Synology NAS FS3400 24 bay NAS FlashStation (Diskless) Retail

Lightning speed with lower TCO


Featuring an 8-core CPU and 16GB ECC RDIMM memory, FS3400 provides more than 137,000 4K random write IOPS, meeting the needs for real-time analytics, online transaction processing, and mission-critical database services. With built-in 10GbE Ethernet, PCIe expansion, and the support of various SAS and SATA drives, FS3400 delivers flexible and economical all-flash server deployment on demand.


RAID F1


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.


Ultimate Backup Solution


FS3400 integrates various backup applications into an intuitive user interface, offering durable storage technologies to safeguard your valuable data on any device.


Fully certified storage virtualization solutions


Synology iSCSI storage fully supports most virtualization solutions to enhance work efficiency with easy management interface. VMware vSphere 6 and VAAI integration helps offload storage operations and optimizes computation efficiency. Windows Offloaded Data Transfer (ODX) speeds up data transfer and migration rate. OpenStack Cinder support turns your Synology NAS into a block-based storage component.

Notes
"Compatible drive type" indicates the drives that have been tested to be compatible with Synology products. This term does not indicate the maximum connection speed of each drive bay.
The maximum raw capacity is not limited by the maximum single volume size. Synology NAS models may utilize capacities over the maximum single volume size as long as each volume created is below the limit.
Each internal volume (may consist of multiple drives) is expandble up to 108TB (with memory less than 32GB) or 200TB (with memory equal to or greater than 32GB).
