Choose by your network links and the space available

The TL-SG108S-M2 fits a planned multi-gig network with up to eight wired links; the TL-SG105 is a five-port Gigabit option with a smaller listed chassis. Treat those as link and placement specifications, not a measured speed result, and confirm hardware version if a tight fit matters.

The buying question

Is the five-port TL-SG105 enough for a gigabit network, or does the setup need the TL-SG108S-M2's 2.5GbE ports and eight-port layout?

The TL-SG108S-M2 is specified with more ports and a higher link-rate tier; the TL-SG105 has fewer Gigabit ports and a smaller manufacturer-listed footprint.

Quick verdict

Choose TP-Link TL-SG108S-M2 8-Port 2.5G Unmanaged Switch if

  • You have 2.5GbE-capable endpoints and a compatible network path, and want the switch ports to support that link rate.
  • You need more than five switch ports and the eight-port layout fits your installation.

Choose TP-Link TL-SG105 5-Port Gigabit Unmanaged Switch if

  • Five 10/100/1000 ports are enough for your planned wired devices and you do not need a 2.5GbE link at the switch.
  • The smaller footprint listed on TP-Link's TL-SG105 page is useful for your intended shelf or desk, subject to checking exact unit clearance.

When the recommendation changes
  • If the network path or devices are limited to Gigabit, the TL-SG108S-M2's higher port rating alone does not establish faster transfers.
  • If exact cabinet clearance matters, confirm the hardware revision and dimensions of the retail unit before choosing by footprint.

The differences that matter

Network Endpoint Link And Port Plan

TP-Link TL-SG108S-M2 8-Port 2.5G Unmanaged Switch

TP-Link's U.S. V1 and V2 pages each list eight auto-negotiating 100 Mbps/1 Gbps/2.5 Gbps ports; the retail hardware version was not identified.[2, 1]

TP-Link TL-SG105 5-Port Gigabit Unmanaged Switch

TP-Link's U.S. TL-SG105 page lists five auto-negotiating 10/100/1000 Mbps RJ45 ports.[4]

What this changes: Count the router link and other wired connections, then check which links have 2.5GbE-capable endpoints. A port's advertised rate is not a measurement of file-transfer or internet speed.[2, 1, 4]

The better fit depends on your priorities

Physical Placement And Footprint

TP-Link TL-SG108S-M2 8-Port 2.5G Unmanaged Switch

TP-Link's U.S. V1 and V2 pages both list 158 × 101 × 25.4 mm (W × D × H); the Amazon item did not expose its hardware revision.[2, 1, 3]

TP-Link TL-SG105 5-Port Gigabit Unmanaged Switch

TP-Link's U.S. TL-SG105 page lists 100 × 98 × 25 mm (W × D × H); the exact retail hardware revision was not exposed.[4, 5]

What this changes: Use the published dimensions as a starting point for desk or shelf planning. If clearance is tight, verify the exact hardware revision and measure the available space before buying.[2, 1, 3, 4, 5]

The better fit depends on your priorities

Best for your routine

A network with multiple planned 2.5GbE links and enough connected devices to use more than five switch ports

Best fit: TP-Link TL-SG108S-M2 8-Port 2.5G Unmanaged Switch

Based on listed features, not comparative testing.

The TL-SG108S-M2 pages list eight 2.5GbE-capable ports. The advantage applies to link planning only; the endpoints and the rest of the network path must also support the intended rate.

A five-port-or-smaller Gigabit setup where the switch must fit a comparatively compact shelf or desk space

Best fit: TP-Link TL-SG105 5-Port Gigabit Unmanaged Switch

Based on listed features, not comparative testing.

The TL-SG105 page lists five Gigabit ports and a smaller chassis than the two SG108S-M2 hardware-version pages checked. Confirm the exact retail version if the space is close.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

A higher offer would need to matter through 2.5GbE-capable links or the need for more than five ports; current offers were not assessed.

Current offers and price history were not assessed, so this comparison makes no purchase-timing recommendation.

Limitations

  • No hands-on or independent speed testing was conducted; the port-rate labels do not establish real-world transfer speeds.
  • The retailer listings did not identify either switch's hardware revision. TP-Link's U.S. V1 and V2 TL-SG108S-M2 pages list the same dimensions, but exact retail revision and fit should be confirmed when clearance is tight.
  • Current offers and price history were not assessed.

Questions shoppers ask

Will the TL-SG108S-M2 make internet or file transfers faster?

Not by itself. Its pages list 2.5GbE-capable ports, but the connected devices and the rest of the network path also need to support the intended rate; the published specification is not a transfer-speed test.

Methodology and sources

Compared TP-Link's U.S. product pages for listed port rates, port counts, mounting options, and dimensions. The available retail listings do not show hardware revisions, so exact-version and tight-clearance checks remain important.

Automated tools helped locate and organize product specifications; no network performance testing was conducted.
