[SFP+] The QNAP does extremely well using auto negotiation on my mixed network. All 10 Gb network cards (OWCPCIE10Gb) from B&H run at rated speeds. Direct 10 Gb transfers between (2) computers with NVMe drives averages slightly over 1 GigaByte/s. Primarily purchased for large backup image and rendered file transfers between multiple computers and a backup server using CAT6a (10'-30') and CAT8 (95'-120') cables. No dropouts during multiple transfers taking place. Plays well with the 2.5 Gb cards and (1) ancient Intel 1.0 Gb card still in the network as well. Also will support up to (8) VLANs, link aggregation and Spanning Tree Protocol.

Management is web based, straightforward and easy to set up or change using either the MGMT RJ45 port or web browser connected via the RJ45 or SFP+ ports. Used an SFP+ module to test all SFP+ ports. All port properly negotiate to NIC rated speeds.

Switch is quiet even though the twin fans spin at 4k+ RPM. (3) fan curve options in setup. The front and top surfaces stay between 89° to 94°F (pyrometer checked). SFP+ module tops out at 95°F on the exposed faces under load. Rated maximum power is 48.6 watts. Internal DC power supply with a 120V AC cord instead of a clumsy 4+ amp power brick.

Have a few more 10Gb cards to purchase yet. Only had it for a few weeks, but it's certainly been doing the job. About the same price as a Netgear 10 port 10Gb managed switch, 4 ports of which are only 2.5Gb. Only about $50 more than a Buffalo 8 port 10 Gb unmanaged switch.

A switch that you can grow into instead of out of for a SOHO network. It's a keeper fer shur.

[10BASE-T] I use these on my SX3008F v1.20 and my SG3428X v1.30. I didn't need to do anything special in the Omada Controller for any 10GbE links to any device.

I also didn't have to do anything special in the settings when linking the SG3428X to an EAP670, even though the latter has a 2.5GbE port. I used a Trendnet PoE adapter, which connects to the module.

With these modules plugged into the 10GbE ports on my SX3008F, and with the other ends of the cables going to my ASUS gaming PC motherboard (2.5 GbE) or to my unmanaged Netgear 5-port switch (1GbE), I needed to check Enable for Flow Control in the Omada Controller for the port.

[1x RJ45] I was looking for a network switch for my office that could handle 10-gigabit connections over RJ-45 (to connect my PC and Synology NAS) but it was difficult to find one that didn't have negative reviews either due to heat or noise. I gave this switch a shot and it's worked extremely well so far. You can set it to use a quiet profile for the fans so that it's not quite as loud and it's been very reliable and performant so far. I can easily transfer While the unit is certainly not silent (the fans are small and can produce a high-pitch hum at times), it is quiet enough to be placed in my office and blends in with the fan noise from other devices like the NAS. Unless it's under a high load or I'm specifically listening for it, I don't even notice it. With larger transfers, I have seen transfer speeds of 550 MB/s to an SSD on my NAS, which is about what I would expect.

[10 Gb/s] I am using only 1 of the adapters in my TL-SX3008F is working out so far (I don't think more than 1 will work in the low powered switch). It is quite hot compared to the DACs and Fiber SFPs. I am using it along with the TL-POE260S PoE+ injector to provide my EAP670 v2 with a 2.5G ethernet connection. The switch doesn't let you choose 2500Mbps on the port because it isn't supported, but it does link at 2500Mbps.

[SFP+] I have primarily used HPE/Aruba switches for the last 20 years but they are becoming more and more expensive and more difficult to recommend to small clients. I tested out a Netgear M4300 3 years ago and it had all of the features I needed for a much better price.
This is actually the 4th Netgear M4300 model I have purchased and its a great device. It has a large feature set similar to the HPE/Aruba switches I have used before. The web and command-line interface are both fairly intuitive. The manuals are very detailed.

[10BASE-T] I needed a few 10G SFP+ to RJ45 Adapters for my tp-link 10G router and 10G switches, where a DAC cable couldn't be used. B&H had them in stock, the lowest price, and the fastest shipping. Keep them spaced out and wear gloves when removing, they get a little warm.

[1x RJ45] Excellent managed switch at a reasonable price. User friendly web management, small form factor and quiet. Well suited for indoor use in a quiet environment. Very pleased.
