For a compact home lab with up to eight 25GbE devices and room for 100GbE uplinks, the MikroTik CRS510-8XS-2XQ-IN is the stronger fit. Choose the QNAP QSW-M5216-1T if you need sixteen 25GbE ports and prefer a web-managed Layer 2 interface. Either can connect a NAS or network card over SFP28, but you must match the cable or transceiver to the hardware and link requirements.
What makes a 25GbE switch suitable for a home lab?
A home-friendly 25GbE switch is one whose port mix, management features, physical media, power, and noise suit the actual rack or workspace. The two options below offer very different port counts and uplinks: MikroTik provides fewer SFP28 ports but adds 100G QSFP28, while QNAP doubles the 25G port count and offers a graphical web interface.
Vendor specifications establish the interfaces and features, but they do not guarantee every third-party NIC, DAC, or transceiver combination. Before buying, check host NIC support, switch FEC behavior, cable reach, and compatibility of the exact media you plan to use.

Which switch should you choose?
Choose the MikroTik for a compact lab with 100G expansion
The CRS510-8XS-2XQ-IN has eight 25G SFP28 ports and two 100G QSFP28 ports. It suits a setup with a handful of 25G endpoints—such as a NAS, servers, or workstation NICs—where faster uplinks or future 100G expansion matter. MikroTik lists the unit at 320 × 185 × 44 mm and specifies maximum power consumption of 31 W without attachments and 51 W maximum. Those figures are manufacturer specifications, not an independent measurement of real-world consumption or noise.
#1 Best Overall
- 4 x 100GbE QSFP28 RJ45 and 8 x 25GbE SFP28 ports to offer a backbone switching capacity of 1200Gbps for uplinking server rooms.
- 600 Gbps Total Non-Blocking Throughput & 1200Gbps Switching Capacity
- Powered by QNAP’s QSS (QNAP Switch System) switch OS that comes with an easy-to-use Web GUI and value-added functions to simplify network set up and management.
- Supports Layer 2 management features, such as LACP, VLAN, ACL and LLDP, for network bandwidth management and security.
- Supports FEC (Forward Error Correction) and IEEE-802.3ap Auto-Negotiation for high compatibility to connect to QNAP 25GbE NAS or NAS installing 100G network cards for high-performance, low-latency computing.
RouterOS v7 is the management platform. MikroTik lists VLAN, ACL, MLAG, jumbo frames, and some Layer 3 hardware offload; consider whether its configuration model fits your comfort level and network design.
Choose the QNAP for more 25G endpoints and web management
The QSW-M5216-1T provides sixteen 25GbE SFP28 ports, a 10GbE NBASE-T copper port, and a stated 820Gbps backbone switching capacity. It is the more natural fit when you need to connect a larger 25G cluster without using 100G uplinks. QNAP describes its QSS web UI as user-friendly and lists Layer 2 LACP, VLAN, ACL, LLDP, and RSTP features.

Do you need SFP28 DAC cables or transceivers?
Yes: an SFP28 port needs compatible physical media to connect to another device. A direct-attach copper cable (DAC) is a cable with suitable SFP28 ends; a transceiver is fitted into the port and connects to a compatible fiber or other supported cabling. QNAP recommends SFP28 DAC cables or transceivers for links to NAS devices, network cards, and switches.

- Accessories may not be original, but will be compatible and fully functional. Product may come in generic box.
The right choice depends on the equipment at both ends, the required cable reach, and the cabling type. Before ordering, confirm that the switch, host NIC, and chosen DAC or transceiver support the intended speed and link behavior, including FEC. Vendor statements about interface compatibility do not certify every third-party combination.
What to check before buying
- Count 25G endpoints: choose eight ports for a smaller lab or sixteen if you need more direct SFP28 connections.
- Plan uplinks: the MikroTik offers two 100G QSFP28 ports; QNAP lists a 10GbE NBASE-T copper port instead.
- Match management to your needs: compare RouterOS v7 with QNAP’s QSS web UI and the Layer 2 features each vendor lists.
- Verify mixed-speed links: confirm the switch, NIC, and selected media support the intended rate; do not assume that a port’s backward compatibility guarantees every combination.
- Check power and noise for the installation: MikroTik publishes maximum power figures, while the cited QNAP page does not state a power figure. Neither cited specification establishes operating noise.
- Budget for media: include the necessary DAC cables or transceivers, not just the switch and NICs.
Verdict
For a compact enthusiast rack that needs up to eight 25G links and 100G expansion, choose the MikroTik CRS510-8XS-2XQ-IN. For a larger group of 25G devices and web-managed Layer 2 features, choose the QNAP QSW-M5216-1T. In either case, validate the exact media and host compatibility before committing to the build.
