Ports
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.
USB ports
The Dell OptiPlex 3080M comes with six 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. Unfortunately, this model doesn't come with a USB 3.1 port. If you need a faster connection for your peripherals, like external Solid State Drive, you will need to choose another model.
Video ports
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 Dell OptiPlex 3080M is featuring a DisplayPort 1.4. 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. Dell OptiPlex 3080M comes with one HDMI 1.4 port(s) on the motherboard. In case your monitor supports another interface, you can always use an adapter.
*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 Dell OptiPlex 3080M comes with one 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.
Dell OptiPlex 3080M has also one M.2 socket(s) that supports both PCIe NVMe (PCIe 3.0 x4) and SATA M.2 drives with speed of up to 4 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.
Best PCIe NVMe drives for Dell OptiPlex 3080M storage upgrade:
