Ports
Dell OptiPlex 7070M provides a fixed set of external I/O ports for connecting peripherals and displays. Port availability and versions determine supported data transfer speeds and display capabilities.
USB ports
Dell OptiPlex 7070M includes six USB ports in total in the following configuration - USB 3.1 Type C; (5x) USB-A 3.0;The model include one USB 3.1 port supporting up to 10 Gb/s transfer speeds.
Video ports
Dell OptiPlex 7070M features two DisplayPort 1.2 outputs, suitable for modern digital displays.
No HDMI output is available on the motherboard.
Motherboard video outputs require a CPU with integrated graphics. Systems equipped with a dedicated GPU must use the video ports on the graphics card instead.
SSD storage - M.2 sockets and SATA ports
The Dell OptiPlex 7070M comes with one SATA port(s) for connecting storage devices.
Dell OptiPlex 7070M has also one M.2 socket(s) that supports PCIe NVMe (PCIe 3.0 x4) or 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.
*Keep in mind that some M.2 connectors may not support SATA SSDs. Check the motherboard manual to confirm compatibility.
