Common board brands include Stark, Yahu, Terminator, Cap, Luker, and others. The most important factor during actual use is typically the smoothness of operation. When connected to USB 3.0, these 75T boards can generally achieve speeds around 5000 Mbps, with a maximum speed reaching up to 6500 Mbps. If you use USB 3.2, speeds can reach around 8500 Mbps.

If your radar machine is a desktop and has extra PCIe slots, you can try using a PCIe to 3.2 expansion card, which can achieve speeds exceeding 10,000 Mbps. However, this might be a bit abstract for everyone; a stable and smooth gaming experience can be achieved with a speed of around 3000 Mbps. For streaming, it is best to have speeds around 5000 Mbps.

Especially if you are only playing games, a speed of 3000 Mbps is sufficient. The speed test is solely related to the USB port, and all boards perform at similar speeds.

So, what does firmware mean? DMA is primarily a PCIe device, and according to PCI specifications, it must include device information in its firmware for the system to recognize and install drivers. Therefore, firmware refers to the information written into the DMA board. Currently, anti-cheat detection primarily checks this firmware code. In simple terms, this firmware can disguise your DMA as a sound card, graphics card, RAID controller, network card, etc., effectively camouflaging the DMA as another device. In practice, as long as the firmware is not open-source, the security risks are generally minimal. Theoretically, single-encryption firmware is the safest option.
