Ports are important and often people don't think about them when buying a PC. For example, if you don't have enough USB ports, using external devices becomes problematic. Before you buy any system, considering your use case, check the number of external devices you are going to use and plan the number of the extension ports accordingly.
The HP EliteDesk 800 G4 Tower comes with eleven USB ports in total. Having more USB ports is always better, but also pay attention to the version of those USB ports. Higher version ports support faster transfer speeds. It is nice to see that the model has a USB 3.1 port. This interface is using 10Gb/s connection and it's very useful when you transfer big files to external drives.
The DisplayPort (DP) is the most widely used digital interface for transmitting digital video and audio between display devices and PCs. It is good to see that the HP EliteDesk 800 G4 Tower is featuring a DisplayPort 1.2. The post version is important if you target higher resolutions with high refresh rate. Although, ver. 1.2 is completely fine for most users, if possible, aim for the higher versions DisplayPort.
The HDMI port is another digital video port you can use to connect external display. It has very similar capabilities to the DisplayPort with few exceptions. However, the HP EliteDesk 800 G4 Tower doesn't have one. This is not a problem if there is on-board DisplayPort.
*Please keep in mind in order to use the video ports available through the motherboard, you need a CPU with integrated graphics card. If you have a dedicated GPU, use his ports instead.
SSD storage - M.2 sockets and SATA ports
The SATA port is one of the places where you can connect a stora gedevice. The HP EliteDesk 800 G4 Tower comes with four SATA port(s). Not enough SATA ports might limit your options for additional storage devices. Think about your use case and decide if the SATA ports provided by this model will be sufficient.
HP EliteDesk 800 G4 Tower has also two M.2 socket(s) that supports both PCIe NVMe (PCIe 3.0 x4) and SATA M.2 drives with speed of up to 3 GB/s. This configuration works very well for both gaming and work related tasks.
The M.2 PCIe SSD connector in combination with an NVMe drive allows for higher transfer rates, compared to the old SATA interface. In some situations, NVMe device connected to the M.2 PCIe socket can be more than 5 times faster.
