    Powerful, scalable, and versatile

    Synology DS1621+ is a powerful and compact 6-bay network attached storage solution designed to store and protect critical data assets. Today’s growing amount of unstructured data requires smarter and increasingly higher performance methods of storing, accessing, and collaborating. Designed for scalability, DS1621+ enables you to start small, then expand as your data grows.

    Turbocharge and expand it

    DS1621+'s dual M.2 2280 slots allow NVMe SSD caching to boost performance by 20x or more for commonly accessed data. It also supports an optional 10GbE NIC for faster network environments and more concurrent users.

    • AMD Ryzen quad-core 2.2 GHz CPU
    • 4 GB DDR4, expandable up to 32GB
    • Up to 110,000 4K random read IOPS and 2300 MB/s sequential write speeds

    File sharing and syncing

    With comprehensive support for all major file sharing protocols — like CIFS, AFP, NFS, FTP and more — DiskStation lets you centralize files in one place and access them using any device. Take files on the road or easily share them with other people, thanks to Synology's easy file sharing and syncing software.

    Bulletproof data backup

    Ensure data remains safe by backing up your computers, servers, and virtual machines to DiskStation, and defend yourself from human-error or ransomware with the multi-version backup. Finally, avoid disaster with the ability to easily back up DiskStation to an offsite location or to any major cloud service.

    Simple to set up, this unit is flexible for growth
    Flexibility, 6 bays, setup fairly easy. I’m using 6 4tb drives giving close to 18tb avg. I’m using it on a win 10 network with 4 total NAS units. Speed and function were exactly as I expected. I store photos and data files all critical. I expect long service from the unit, drives will be changed around the 2-4 yr service life on a 24/7 cycle.
