So ordered due to the mostly very good reviews and I was not disappointed!
The installation on existing Telekom Speedport W701V router was easy and smooth. I run to the switch 2 laptops, 2 PCs and a Windows Home Server; all could immediately build 1GB connections.
The speed of the switches is impeccable. The transfer rate depends more on connected devices as the switch itself. The peak I could achieve when copying 203GB (about 400 files) from my Acer H340 Home Server on my desktop PC: up to 102MB / sec. The 203GB were copied after about 47 minutes; with mixed file sizes (a few kB to GB) moves the edge of about 20MB / sec to 70MB / sec. Bottleneck are sending and receiving hosts here. Performance default's, in my view, therefore, nothing to complain about. As cable I use commercially available Cat 5e cable. All statements MB-figures come from Windows 7 computers; the values were stable over a long time respectively.
By comparison, the integrated into my router 100Mbit switch creates a maximum of about 11MB / sec.
Clearly, the case of TP-Link switches is made of plastic, but optimally processed. Purchase Another important factor was the low power consumption compared to other switches for me.
The switch provides high performance at low cost. I highly recommend it and would buy it again at any time! And the settlement by Amazon as always was top ...
