The Synology DiskStation DS1621xs+ is a boutique, studio-grade 6-bay storage powerhouse designed to streamline high–bandwidth business infrastructure, on-the-fly 4K video editing loops, and dense virtualization workloads. Driven by an elite Intel Xeon server processor and a hardware-accelerated encryption pipeline, this model delivers a staggering 3,100 MB/s of sequential read throughput and over 265,000 random read IOPS to eliminate any office network congestion.

Operating on Synology’s specialized tier of the DiskStation Manager (DSM) platform, the DS1621xs+ prioritizes data integrity by running professional-grade DDR4 ECC memory that actively fixes single-bit digital errors automatically. Its broad 6-bay layout can comfortably support high-fault-tolerance traditional RAID 6 storage pools. As your enterprise storage footings scale, the system adapts seamlessly, allowing you to daisy-chain two external expansion chassis to achieve 16 total drive bays, drop in multi-gig caching modules, or mount a dedicated 25GbE fiber line to anchor high-density virtual machine environments.
