If you need VLAN+QoS features, I think TL-SG108E is more appropriate because it has web interface to configure these feature, but TL-SG1005D doesn't have web interface. As for the power consumption, I'm a little curious about how you want to use it. I don't think 2.4W and 3.7W have a lot of differences. They both are not too high. Of course, if you have one device plugging in and multiple devices plugging in, the consumption will be different. And if you have different traffic running, the consumption will also be different. So I think it's difficult to calculate the minimum consumption. For your note, I don't know what's wrong with your link, but mine is working fine: https://www.tp-link.com/us/business-networking/easy-smart-switch/tl-sg108e/v5/#overview Only some managed switches have management VLAN as it is designed for more professional users.

Initially I was going for the TL-SG108E with much excitement, but once I realized its management interface was using HTTP and it was accessible on all VLANs I got disappointed a bit, because even my home's ISP router uses HTTPS and I found it weird for a business switch not to.

 

I will connect 3-4 PCs on it, most of which will not be active 24/7. I need to isolate some of them from the others, that’s why I need the VLAN support (there are some machines with high-risk to be hacked in my network and some devices that should be kept safe at all costs).

But after I noticed the shortcomings of TL-SG108E I started thinking whether I should buy a simple unmanaged switch for now (because I really need a switch asap…) and later buy a more expensive one, with VLANs support, once I do my research. Because, what protection do VLANs provide when everyone (from all VLANs) can log into the switch (e.g. by brute force, by capturing network traffic from the login page and stealing the credentials, and who knows what else…) and change the VLAN configuration?

I don’t want if for a home application, but I am not Google and Microsoft either… Maybe staying with less protection for a couple of months more is not the end of the world.

But I think that the price for those kind of switches that I want is 3 times the price of the TL-SG108E (unfortunately), because they usually include other features that I don’t need, so I have some doubt if I should spend so much money.

  

At least, this guy has managed to somewhat “secure” his TL-SG108E by crashing its management interface (!):

Search for : "Not So Smart: TP-Link TL-SG105E V3.0 5-Port Gigabit Easy Smart Switch" (couldn't add a direct link)

Maybe I can take my chances with this hack (assuming that it still works) and avoid reconfiguring the switch often.

If anyone from the TP-LINK staff reads this, I think that a built-in way to gracefully shut down the management interface would be very nice.

It would secure the switch without any work required from the company or CPU power required by the switch.

I wish this feature gets included in a future firmware.

Then, you just have to restart the switch to get into the management interface.

 

Although, a loss of power will also cause the management interface to be re-enabled. L
