Why use a port replicator for a laptop?<\/h2>\n

A port replicator<\/b> is an ideal tool for quickly turning a laptop into a full workstation. It lets you centralise the connection of several essential peripherals: external monitor, keyboard, mouse, hard drive, network connection, and more. This is particularly useful for laptops with only a few ports.<\/p>\n

To work, it needs a USB 3.0 connection<\/b>. There are also more modern models using USB-C<\/b> technology, which will be covered in a separate review.<\/p>\n

Three models tested in this review<\/h2>\n

This comparison looks at three port replicators currently available on the market:<\/p>\n

    \n
  • A compact model from one brand (ref. PR7.1)<\/li>\n
  • A docking station referred to as Pro Dock<\/li>\n
  • A third model known as 3005pr<\/li>\n<\/ul>\n

    Comparison table of technical specifications<\/h2>\n\n\n\n\n\n\n
    Model<\/b><\/td>\nMain connection<\/b><\/td>\nVideo outputs<\/b><\/td>\nUSB ports<\/b><\/td>\nAudio connections<\/b><\/td>\n<\/tr>\n
    PR7.1<\/td>\nUSB 3.0 (type B)<\/td>\nHDMI, DVI<\/td>\n2x USB 3.0 (QuickCharge)<\/td>\nNot available<\/td>\n<\/tr>\n
    Pro Dock<\/td>\nUSB 3.0 (type B)<\/td>\nDisplayPort, DVI<\/td>\n3x USB 3.0, 2x USB 2.0<\/td>\n3.5 mm headset\/mic<\/td>\n<\/tr>\n
    3005pr<\/td>\nUSB 3.0 (type B)<\/td>\nDisplayPort, HDMI<\/td>\n2x USB 3.0, 4x USB 2.0<\/td>\nAudio in and out jack<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    The Pro Dock and 3005pr<\/b> let you use multiple screens and include audio options. By contrast, the PR7.1 does not offer any audio port<\/b>, which may be a limitation for certain professional uses.<\/p>\n

    Operating system compatibility<\/h2>\n
      \n
    • PR7.1 and 3005pr<\/b>: compatible with Windows XP, Vista and later versions<\/li>\n
    • Pro Dock<\/b>: usable from Windows 7 onwards, and also compatible with macOS<\/li>\n<\/ul>\n

      Box contents<\/h2>\n

      Each port replicator comes with:<\/p>\n

        \n
      • A power adapter from 20W to 65W depending on the model<\/li>\n
      • A USB 3.0 cable (Type A to Type B)<\/li>\n
      • Documentation (instructions, product sheets)<\/li>\n<\/ul>\n

        Model-specific extras<\/b>:<\/p>\n

          \n
        • The PR7.1 is the only one to include a driver CD<\/b>.<\/li>\n
        • The other two models provide additional video adapters<\/b>.<\/li>\n<\/ul>\n

          Size and footprint<\/h2>\n

          The PR7.1 replicator is the most compact<\/b>, which makes it ideal for mobile users. The Pro Dock has a moderate footprint, while the 3005pr is twice as bulky<\/b>, which may be an issue depending on the available desk space.<\/p>\n

          Test conditions and protocol<\/h2>\n

          Test PC configuration<\/b>:<\/p>\n

            \n
          • Intel i5-6200 processor (2.7 GHz)<\/li>\n
          • 8 GB DDR4 RAM<\/li>\n
          • Crucial SSD to measure USB performance<\/li>\n<\/ul>\n

            Measured criteria<\/b>:<\/p>\n

              \n
            • 2D and 3D display latency<\/li>\n
            • Ethernet throughput (with iPerf)<\/li>\n
            • Read\/write speed over USB 3.0<\/li>\n<\/ul>\n

              Performance results<\/h2>\n\n\n\n\n\n\n
              Model<\/td>\n2D latency<\/td>\n3D latency<\/td>\nEthernet<\/td>\nUSB read\/write<\/td>\n<\/tr>\n
              PR7.1<\/td>\nAlmost imperceptible<\/td>\nClearly noticeable<\/td>\n56.5 MB\/s (452 Mbps)<\/td>\n412.9 \/ 199.2 MB\/s<\/td>\n<\/tr>\n
              Pro Dock<\/td>\nAlmost imperceptible<\/td>\nClearly noticeable<\/td>\n57.1 MB\/s (456.8 Mbps)<\/td>\n414.8 \/ 199.6 MB\/s<\/td>\n<\/tr>\n
              3005pr<\/td>\nAlmost imperceptible<\/td>\nAlmost imperceptible<\/td>\n56.4 MB\/s (451.2 Mbps)<\/td>\n412.6 \/ 198.6 MB\/s<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

              Technical conclusion<\/b>: all the port replicators deliver solid performance, but only the 3005pr keeps 3D latency under control<\/b>.<\/p>\n

              Recommended usage profiles<\/h2>\n

              H3: For everyday use<\/b><\/h3>\n

              Thanks to its compact size and low cost, the PR7.1 is perfect for occasional users who value simplicity.<\/p>\n

              For a flexible and stylish workstation<\/h3>\n

              The Pro Dock offers a wide range of ports with dual monitor output<\/b> and audio ports. Its reasonable size and matt finish make it both practical and good-looking.<\/p>\n

              For demanding needs<\/h3>\n

              The 3005pr is recommended for users who want to run 3D applications<\/b>, connect several screens and benefit from full audio connectivity. Its price is moderate compared with its capabilities.<\/p>\n

              Overall verdict<\/h2>\n
                \n
              • The PR7.1<\/b> is a simple, lightweight model suited to everyday use<\/b>, but limited for more complex setups.<\/li>\n
              • The 3005pr<\/b> delivers the best overall performance<\/b> and is ideal for power users, despite its larger size.<\/li>\n
              • The Pro Dock<\/b> offers a good balance of design, compact size and connectivity<\/b>, even though it sits in a slightly higher price bracket.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
