Synology DS1621+ IronWolf External HDD Overview

This B&H Kit combines the Synology DiskStation DS1621+ 6-Bay NAS Enclosure with six Seagate 4TB IronWolf 5400 rpm SATA III 3.5" Internal NAS HDDs for a storage capacity of 24TB.

Synology DiskStation DS1621+ 6-Bay NAS Enclosure

Built with a quad-core processor, an AES-NI hardware encryption engine, and Btrfs file system support, the DiskStation DS1621+ 6-Bay NAS Enclosure from Synology is a high-performance system designed to store and protect critical assets, while also offering storage scalability so you can start small and expand as your data grows. Boost storage performance by installing dual M.2 2280 NVMe SSDs for high-IOPS system caching, or enhance network speeds by adding a 10GbE SFP+ or RJ45 NIC to the PCIe 3.0 x8/x4 slot. This NAS is equipped with six drive bays that are capable of natively supporting 3.5" SATA hard drives, as well as 2.5" SATA hard drives and SSDs, for data storage. Using its six drive bays, this NAS will allow you to store and share many files, including videos, music, photos, and documents with up to 2048 user accounts and 1000 maximum concurrent connections.

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.

  • File and folder level data restoration offers users who wish to restore only a specific file or folder more flexibility.
  • Flexible Shared Folders and user quota system provides comprehensive quota control on all user accounts and shared folders.
  • File self-healing allows Btrfs file systems to auto-detect corrupted files using mirrored metadata and to recover broken data using RAID configurations.
  • 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.

    Synology DS1621+ IronWolf External HDD Reviews

    extremely slow and buggy on mac

    By jerry
    Rated 1 out of 5
    Date: 2025-03-25

    very antiquated and flimsy. the plasticky enclosure amplifies the noise from the spinning hard drive. it's so slow it took days to move 17TB of data. it's like old windows pc from the 80s. transferring large folders resulted in frequent crashes and errors. this is very old tech and not user friendly. time to update this grandpa tech. shame on synology to still selling this antique!

    Awesome NAS

    I am biased toward Synology products as they have always been consistent and work without issues for many years. Also their support is outstanding.
