  • Data centers routinely replace network hardware, making Mellanox ConnectX-3 and Intel X520 cards inexpensive on the used market.

  • SFP+ cards commonly use DAC cables for inexpensive, low-power links spanning a few meters; longer distances require fiber and optical transceivers.

  • Linux usually supports both cards with mainline drivers, while compatibility on Windows 11 varies considerably, especially for used models.

  • RJ45-based 10GBase-T cards generate more heat, requiring airflow; the X520 also needs a full-length PCIe x8 slot.
