8 Port 10Gb RJ45 Web Managed Network Ethernet Switch 8 x 10G Base-T Port | Multi-Gig 10G-5G-2.5G-1G | 19 Inch Rack Mount | Built-in Fan | 160G Bandwidth | 10Gbps for 10G NAS, PC, WiFi7 Router

No issues with these. I haven't tried the SFP connection with optical. It would be ideal for daisychain more than one of these together. It does connect at 2.5Gbps and gives the rated speed. I didn't feel any heat concerns with it. Just plug and play. Your modem/router needs to support 2.5Gbps and ISP to support 2Gbps speeds or faster to see the results on speedtest with a 2Gbps plan for faster. Home use device to device on LAN you should see about 220MB a second file transfers depending on your device capabilities.

I recently built a NAS, and decided it was time to go to 10 GBE on my LAN. I have a Mac Studio, a home-built PC, and a home built NAS, all with 10GBE interfaces. I also have a 1GBE POE switch that powers 8 Raspberry Pis. a work laptop on a docking station, and all of it connects to a router that handles Internet access. First off - I am reviewing the 8 port 10GBE switch. Out of the box, it will work, but may not be set up ideally for your configuration, especially if you want VLANs. If you want VLANs, you will need to have a bit of knowledge to get started - this switch supports them, but the documentation is sparse - be prepared to do some research if you are planning to set them up. I say that from experience, and you can lock yourself out if you do not know what you are doing. Luckily, there is a reset button, and holding it down for a while (20 -30 seconds, I think) will reset the switch to factory settings. Performance has been as expected, and I have not experienced any performance issues so far. I did get CAT 6A cables - I'm not sure you could get 10GB performance out of CAT 5, even with short cable runs. When researching this switch, I saw mention of it being fanless. I would like to state that this is not the case with this switch. I am happy that it has a fan though - I'm not sure I would trust one that is fanless, given that it does produce a little bit of heat. Noise is acceptable to me (it is set up in my bedroom, along with a NAS that is notably louder), but if you are expecting it to be silent, you may be disappointed. Finally, I wanted to talk about the rack mount brackets. I did not put mine in a rack, but I did mount it vertically on a wood surface. The brackets can be attached for a front mount, bottom mount, or top mount configuration. I'm not sure if this was intentional or not, but I took advantage of it to mount the switch out of sight.

I purchased four of these RealHD eight port managed 10gbps switches. The build quality seems good (heavy metal enclosure, RJ45 ports and other fit and finish good.) The management through the web page is somewhat basic, but does what it needs to. I'm getting great throughput and no problems with a large number of different interfaces connected to them auto negotiating appropriately. The power cable is harder to get seated in the IEC socket on the back than a lot of other equipment and the cord is shorter than I needed for a couple of them but both were minor issues. Of the four switches, I did have one that would lose its config when powered down. I contacted support (through cctvsupply, inc, which surprised me originally as amazon mentions it as the RealHD store.) They called back quickly and shipped a replacement out very quickly with a label to return the switch with the problem. Excellent support. Five stars for the support!

This switch works as intended. Nothing fancy or special about it—it just does the job it’s meant for. Plug it in, connect your cables, and it works without any issues. Solid and reliable for basic network expansion.

It does work, and is very cheap. You're not going to get the absolute maximum possible performance compared to a quality name brand switch that costs twice as much, but if you don't care about squeezing every last ounce of performance, this switch should do fine.

Simple plug-n-play switch to connect multiple 2.5G devices to your network. Plugs into a standard electrical outlet for power, via a plug adapter, and provides 5 2.5Gb ports (1 in and 4 out), plus one 10Gb SFP port. It's quiet and small enough to place almost anywhere. Accepts standard RJ-45 network cables, which should be CAT 6 or above for full speed transfer.

The best switch I have ever had in my house. Data flys around the house just need to complete my network wiring in the house all cat 6a. By doing this no slow down with tv or another streaming product. Or ps4 Apple tv

Needed a switch for 2.5Gb NAS transfer speeds. This works great. Love how cheap it is. The only thing I didn't like was that the wall mount holes did not have much clearance for screws/nails with large heads. The heads have to be really flat to fit. I had to visit a hardware store to find something that would fit.
