during your talking about #5, the Netgear switch, the video kept showing OTHER switches, and it was very confusing to see an 8-port switch whileyou kept saying "5-port switch".
if you just didn't have any video of the 5-port switch, why not just TAKE SOME? and if your argument is that you did not have one of those switches in hand, then how can you possibly talk about them as though you know they are the BEST, if you've never even tried them out?
I defiantly can't live without this...
ОтветитьI have been using Ethernet PoE switches from CONSTEEL ELECTRONICS in my projects for several years now, I recently installed the IES6210-8P2GC and I am very happy with it, as far as I know, my customer is also delighted, the whole network works for him just as he dreamed.
ОтветитьIt's important to note that there is a great difference between Gigabyte and Gigabit. Whenever you see 2.5G or 2.5 GbE on a device like a switch, the G/GbE stands for 'Gigabit' or 'Gigabit Ethernet'. I appreciate that the speaker in the video may have seen the mistake afterward.
The below are the CORRECT FIGURES:
1 Gb/Gbit/Gbps = 1,073,741,824 bits/s = (1,073,741,824 x 0.000000125 [conversion for MB]) = 134 Megabytes / MB/s
2.5 Gb/Gbit/ Gbps = 2,684,354,560 bits/s = (2,684,354,560 x 0.000000125 [conversion for MB]) = 335.5 Megabytes / MB/s
In reality, due to network overhead, a 2.5 Gbps connection will give a real experience as low as ~260 MB/s in some cases, provided there is a 2.5 G capable network card installed in both the transferring and receiving devices.
The below is the erroneously purported performance of the switches in this video, YOU WILL NOT get the following performance:
1 GB/ Gigabyte/s = 8,589,934,592 bits/s, this would mean the switch can facilitate transfers at 8 Gb/Gbit/Gbps
2.5 GB/ Gigabyte/s = 21,474,836,480 bits/s, this would mean the switch can facilitate transfers at 20 Gb/Gbit/Gbps, which it cannot.
If you work with large files (1 GB < 10 GB) on a regular basis - which I only expect from those who are storing/transferring high resolution/detail graphics or video files - then a descent 2.5 Gb switch will be fine for you but your device and the target destination device (Maybe a NAS device or a server) MUST EACH HAVE A 2.5 Gb NETWORK CARD INSTALLED to take advantage of the transfer rate and the [Network/RJ45] wall ports in your building (if applicable) must be connected by cables that are CAT 5e or later if the distance of cables is <55m or CAT 6 or later if the cable distance is >55m.
I've worked in corporate IT for 11 years and now advise businesses on IT infrastructure purchases, It's good to read up on new tech and look for recommendations but please DO NOT BY ANYTHING without speaking to an experienced individual.
Did you review and test these switches yourself? if not, what exactly is the purpose of this video?
ОтветитьWhich one is for high end data?
ОтветитьMy modem has 3 1gbps port and 1 2.5 gbps port and i find none of my stuff (arlo cameras, philips hue lights, sonos speakers) work when their base stations are plugged into the 2.5 gbps port. So i would beworried that the dlink switch would be useless to me since it is all 2.5 gbps ports
