The DS1621+ runs on the Synology DiskStation Manager (DSM) OS, which is a browser-based operating system that helps to simplify managing your Synology NAS. Its CPU is a 2.2 GHz AMD Ryzen V1500B Quad-Core and its 4GB of DDR4 ECC RAM, which be upgraded to 32GB, allows frequently used files and applications to be quickly accessed. The NAS is capable of sequential write speeds of up to 2300 MB/s, as well as 110,000 4K random read IOPS.

Also featured are three USB 3.2 Gen 1 Type-A ports, plus two eSATA ports for storage expansion, and network connectivity is achieved via the four Gigabit Ethernet ports, allowing your stored data to be shared with users throughout the network. For those who require RAID support, the DS1621+ supports RAID 0, 1, 5, 6, and 10, as well Synology Hybrid RAID and Basic RAID, each of which offers performance, data redundancy, or a combination of both. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilized.

The DS1621+ is engineered to be energy efficient. Not only does it offer two 92 x 92mm fans to help keep the system running cool, it supports numerous scheduled power on/off cycles and hard drive hibernation to further reduce power consumption and operation expenses.

The Synology DiskStation DS1621+ 6-Bay NAS Enclosure operates on 100-240 VAC at 50/60 Hz and includes an accessory pack, a power cord, and two RJ45 LAN cables. If you need to expand its storage, the DS1621+ can be connected to two DX517 expansion units. Protection is provided by a limited 3-year hardware warranty.

  • Inline compression compresses data before writing it to the drive, to optimize storage use and reduce write commands to the drives.
  • On-Premises Collaboration

    Synology Collaboration Suite allows businesses to host their own fundamental IT services for file sharing, concurrent document editing, emails, instant messaging, and more. Create a multi-user collaborative environment while leveraging private cloud infrastructure to reduce privacy concerns. Multilayered security enables secure access to files and services, even for a distributed or remote workforce across Windows, macOS, Linux, Android, and iOS platforms.

  • Synology Drive enables data access, synchronization, and backup via web portal and desktop applications across Windows, macOS, and Linux platforms. Intelliversioning saves historical versions while minimizing storage space usage and supports on-demand data restoration.
  • Synology Office includes Documents, Spreadsheets, and Slides. The online collaborative editing environment allows multiple users to edit, comment, and share data together.

  • Synology Calendar helps teams keep track of what's important, with easy to use sharing and scheduling functionality, keeping everyone on the same page.
  • Running & Protecting Virtual Machines

    Synology Virtual Machine Manager (VMM) is a hosted hypervisor that lets users easily set up virtual machines running Windows or Linux based platforms and a virtualized version of Synology DSM, Virtual DSM, on the DS1621+. Using VMM, users can build up a cluster environment with multiple Synology systems for flexibility to perform online migration based on load balancing and resource allocation requirements. High-performance snapshots, replication, cloning, and recovery mechanisms enable comprehensive management and data protection on each VM.

    DSM also simplifies the provisioning and management of storage for virtual machines. Certified for VMware vSphere, Microsoft Hyper-V, Citrix XenServer, and OpenStack, Synology systems can integrate with your virtualization platform of choice through iSCSI or NFS protocols. Install Synology Storage Console for VMware/Windows for additional management convenience and functionality right in the hypervisor.

    Comprehensive Data Protection Options

    The DS1621+ includes a range of backup solutions to protect local, remote, and cloud-based deployment environments, all-inclusive with the device. Easily set up automated backups and even enable self-serve functionality for reduced maintenance and upkeep.

  • Back up data on Synology NAS: Snapshot Replication enables fast snapshots for point-in-time file versioning, which is great for rolling back unintended file modifications and protecting your data against ransomware attacks. Hyper Backup offers a wide range of destinations for backups of your NAS, including for both local and remote on-premises and cloud storage providers.
  • Back up business infrastructure: Synology Active Backup suite is a collection of powerful backup solutions built to protect Windows systems and servers, VMware and Hyper-V VMs, other file servers, and even Google G Suite and Microsoft 365 SaaS clouds.

    With Synology Surveillance Station, the DS1621+ becomes a powerful VMS solution. With support for up to 40 IP cameras, you can cover large installations.

  • 7600 supported cameras, and counting: Find a compatible camera from updated compatibility lists to match your video requirements and budget. ONVIF support prevents vendor lock-in.
  • Private and subscription-free: Unlike cloud-based cameras, you can keep your recordings private and on-premises. Simple per-camera licensing with no subscriptions needed to access your data.
  • Flexible monitoring & control: Access your surveillance system from a web browser, dedicated desktop clients, or from the DS cam mobile app. Internet-optional.
  • Automation & notification: Set up rules to trigger specific actions when an event occurs, such as automatically taking a picture when motion detection is triggered. Get notified by email, SMS, or push notification so that you can act quickly.

    Awesome diskstation, works great!

    With Synology you're really paying for the software and tight integration. Sure you can build your own NAS and use some free software but the support and easy setup Synology offers is second to none. Make sure you know that this isn't the choice for running a Plex server if you expect to be transcoding since it can't handle it but for everything else it has been fantastic. I'm backing up my PC to the NAS then using the NAS to backup to backblaze b2 backup via hyper backup and once getting it setup it has been reliable and fantastic. Definitely a solid bit of hardware and software, looking forward to expanding to 10gbe in the future.

    I did not know a thing about NAS units but bought this one and it works great, easy to install. Placed 6X10TB Ironwolf drives in it and it just hums along. Running Plex on it right now, but have plenty of space for a few years for my future images.

    I love this thing! I stacked it with 12 TB drives and when I need more I can expand. Plus I can edit from it!!

    Fantastic NAS

    I am not a pro NAS user, and I finally upgraded from MycloudPr4100 with 16GB (bought it 4 or 5 years ago). Synology system was very easy to setup. I put in WD Red Pro 16TB NAS Hard Drive, and the whole system is working very smooth. The read/write speed is approximately 3 times more than the previous NAS. The Synology software solution is also fantastic, and easy to use ...

    For easy redundant backups.

    storage pool vs shared folderPurchased to load up many old usb flash drives, and external hard drives, to consolidate all the data had lying around. Was in backup-hell, could not find old files. Like the fact that it has node.js module. Currently writing a node.js detect duplicates to free up even more space. Note: Does not have partitioning like a pc drive. RECOMMEND: before starting read DSM user manual about, Choose a RAID Type, and understand the concepts storage pool vs shared folder vs RAID vs drive
