Synology RackStation RS3621RPxs 12-Bay NAS Enclosure

The Synology RS3621RPXS is a rack-mountable 12-bay NAS enclosure created for organizations that need dependable, high-speed shared storage without a steep learning curve. It runs on a six-core Intel Xeon D-1531 processor at 2.2 GHz and ships with 8 GB of error-correcting DDR4 memory, so it keeps large projects moving smoothly while helping safeguard data in memory.

For teams that edit large media files, run virtual machines, or manage sizable databases, the system offers sequential read throughput up to 4718 MB/s and nearly 189 000 IOPS. Those numbers translate to quick file transfers and responsive applications, even when many users connect at once.

Business continuity is built in. Two hot-swappable 500 W power supplies keep the system online if one unit fails, and the enclosure supports RAID 0, 1, 5, 6, 10, Basic, and JBOD to fit a wide range of protection and performance needs. The Btrfs file system adds snapshot capability and self-healing features that help prevent silent data corruption.

Four Gigabit Ethernet ports support link aggregation for higher throughput or network failover. If requirements grow, two PCIe Gen 3.0 slots accept 10 GbE network cards or NVMe cache adapters, and the chassis can expand to 36 bays with up to two Synology expansion units. In short, the RS3621RPXS scales alongside your business instead of forcing an early replacement cycle.

Administrators will appreciate the familiar web-based DiskStation Manager operating system, which consolidates data protection for Windows and Linux servers, virtual machines, Microsoft 365, and Google Workspace. Whether you are setting up a reliable file server for a design studio, a backup target for branch offices, or shared storage for a virtualization cluster, the RS3621RPXS offers a straightforward path from installation to day-to-day management.
