Synology is one of the top-tier vendors in the commercial off-the-shelf (COTS) network-attached storage (NAS) market for SOHOs, SMBs, and SMEs, with QNAP being the other major player. While QNAP has a wide variety of hardware platforms to choose from in each market segment, Synology has been big on segmentation – restricting Xeon CPUs and native 10GbE to their rackmount offerings. Only their Annapurna Labs SoC-based desktop units have had 10G SFP+ support till now. That changed recently with the introduction of the DS1621xs+.
The Synology DS1621xs+ uses a Broadwell-DE Xeon-D processor (D-1527) – These SoCs are a better fit for storage platforms compared to the networking-focused Skylake-D SKUs. The 6 built-in 3.5″ hot-swappable drive bays are complemented by two M.2 2280 NVMe SSD slots. There are two 1 GbE LAN ports and a 10GBASE-T port. Two eSATA ports help the unit support two DX517 expansion chassis, allowing the unit to support a total of 16 bays.
On the software side, similar to all other x86 NAS units from Synology, the DS1621xs+ also comes with support for both ext4 and btrfs internal volumes. Synology claims read speeds of up to 3100 MBps with additional 10G NICs in the expansion slots.

It is heartening to see Synology finally introduce 10GBASE-T NAS units in the desktop form-factor. The DSM software carries some unique applications (like the Synology Office suite) that QNAP doesn't currently have in their QTS operating system. On the other hand, QNAP's hardware variety – particularly in terms of NBASE-T and 10GbE support even in their SOHO offerings is also attractive. Overall, it is good for consumers to have more options to choose from in the COTS NAS market.
