Synology DS1621+ 6-Bay NAS Server, AMD Ryzen V1500B, 4GB DDR4

The DS1621+ holds up to six 3.5-inch drives, and you can mix hard drives or SSDs to suit your workload. Because the bays are hot-swappable, a failed or outgrown drive can be replaced without shutting the system down, which keeps shared folders, backups and media libraries available to everyone on the network. Starting with a few drives and adding more later is a practical way to spread the cost of building up capacity.

Synology lists support for RAID 0, 1, 5, 6, 10 and Hybrid RAID. That range lets you choose between maximum speed, mirrored safety or a balance of capacity and redundancy. RAID 6, for example, tolerates the failure of two drives, while Hybrid RAID makes it easier to combine drives of different sizes. Whichever layout you pick, the six-bay chassis leaves room for configurations that protect important files against a single hardware fault.

At the heart of the system is an AMD Ryzen V1500B quad-core processor running at 2.2 GHz. It handles multiple simultaneous users, file transfers and background tasks such as backups and RAID rebuilds without bogging down. Paired with 4 GB of DDR4 memory, the platform is built for steady, everyday multi-user operation in an office or a demanding home network rather than for a single occasional user.

Four 1GbE RJ-45 ports give you plenty of options for connecting the NAS to your network. You can spread traffic from several workstations across separate links or keep a spare connection for redundancy, depending on how your switch and network are set up. For teams that move large project folders, photo archives or video files around every day, multiple network ports help keep transfers flowing.

Beyond the internal bays, the DS1621+ offers three USB 3.0 ports and two eSATA ports. USB 3.0 is handy for copying data from portable drives or attaching an external disk for extra backups, while eSATA provides another route for connecting external storage. These ports make it simple to bring existing drives into your storage workflow without opening the case.

The compact tower design fits on a desk, shelf or in a small server corner without the need for a rack. Two fans move air across the drive bays to help keep the disks at stable temperatures during long periods of continuous operation. The unit weighs 6.3 kg without drives, so it stays firmly in place while remaining easy to move between rooms or offices.

This NAS suits small and medium businesses, creative professionals and tech-savvy home users who need more capacity and redundancy than a two- or four-bay unit can offer. It works well as a central file server, a backup target for several computers or a shared archive for photos and video, with room to expand as your data grows.
