About this deal

Amazon has the TP-LINK 2.5GBit/s PCIe network adapter for £21.24, other seller have it for £24.99 or more.
The 2.5 Gigabit PCIe card could be beneficial for motherboards with only 1Gbit/s Ethernet ports, providing a solution for those requiring faster speeds at 2.5Gbit/s. Additionally, it serves as a convenient option for individuals needing an extra high-speed Ethernet port on their system if you're building a NAS or something like that.

    am I missing something what is the point of a 2.5 port when the fastest speed offered by ISP is about 900 MB.

    Nice price.

    But where are the deals on 2.5 Gb switches??? (edited)

    I use one of these and works perfectly

    My main PC has 2.5gb on the motherboard and you can pick up cheap 2.5gb switches now on Amazon.

    Allows me to transfer movies over to my plex server at 279MB/s which is much better than using old and dated 1gb gear. 2.5gb should become the new mainstream standard imo

    jasejames:

    Oh right OK, mine seem OK, in the sense that ESXi picked them straight up and they register as 2.5G on the switch. But yes buying from China can be a minefield!

    Perhaps I need to run more detailed tests - they're in a lab and I bought them for compatibility rather than performance...

    I225s are hit and miss also, Intel had a lot of issues that resulted in 5/6 revisions before they moved to the i226. If you can get an i226 or last revision i225 you'll be fine but it's a minefield.

    The best cards seem to be based on thr Aquantia Marvell chips but they are a lot more expensive and the cheap Chinese ones are prone to heat based failure. (Although they also support 10/5gbe so there is that for the expense). I couldn't justify spending more than 50 on a NIC. (edited)

    Pretty pointless at home, I have a very large network at home which includes 6 switches, 3 servers, NAS, various cameras and much more. As others have said, its all well and good having a 2.5GB card, but without the switches to match it makes no difference.

    How's it 2.5 times faster than 1?

    I bought used Intel 10Gbe card for £30. No point in getting 2.5Gbe when 10Gbe can be had for only a little more used.
