Laptops usually do not have many ports and thus only a limited number of peripheral devices can be connected to the laptop through the ports provided on the laptop. Hence docking stations are used as they provide a way to connect multiple peripheral devices simultaneously, without sacrificing the portability of the laptop.
WD15 vs WD19
The main difference between WD15 and WD19 is the data rate of connectivity provided by the devices and the type of ports available. WD15 provides a data rate interface of 5GB/s, whereas the dell WD19 is offered with a data rate interface of 10GB/s which provides a faster data transfer rate.
Dell WD15 is a docking station offered by Dell. It uses a mini display female port for connecting to a system. It can provide an interface data rate of 5GB/s and can support 3 displays of different types. Hence the docking station can provide reasonable connectivity with decent speed and compatibility.
Dell WD19 is another type of docking station provided by Dell. This docking station is more portable as it is provided with a USB 3.1/ USB 3.2 type-C connection port for connecting to a system. Thus it is compatible with more devices and it is also faster, as it can provide a data rate interface of 10GB/s.

What is WD15?
Dell WD15 is a docking station provided by Dell which is used to connect different peripheral devices to a computer. The docking station is connected to the system using the system connection port.
WD15 is provided with a mini DP female port for connecting it to the system. The connection is made through a detachable cable.
The device provides a data rate interface of 5GB/s for transferring data between the peripherals. It can support 3 display devices with the three types of ports provided, namely HDMI, VGA, and Mini DP.
Along with display devices, it can also support audio devices using the 3.5mm headphone/microphone jack provided in the device.
The device can support display resolutions of 3840 X 2160 at 30Hz, 2560 X 1600 at 60Hz, and 1280 X 1024 at 60Hz. Thus it can connect to most display devices and operate at a decent speed.
The docking station is compatible with all Dell devices and most other laptops as well. The dock is also provided with two USB 2.0 Type-A ports and three USB 3.1and USB 3.2 gen 1 Type-A ports.
This allows for peripheral support of different types of devices, for quick and easy connectivity. The station is also very portable, because of its smaller size and less weight.
What is WD19?
WD19 is a docking station offered by Dell for connecting different peripheral as well as other connected devices to a laptop. It is a comparatively faster docking station than other devices in its range.
The station uses USB 3.1 and USB 3.2 Type-C male ports for connecting to the system. This is possible because of the integrated cable provided with the device, enabling it to connect to devices that use either of the ports.
The docking station provides a data rate interface of 10GB/s, allowing much faster data transfer. The connection to other peripheral devices is made by the ports provided on the unit.
WD19 is provided with two USB 3.1 and USB 3.2 gen 2 Type-C ports, along with three USB 3.1 and USB 3.2 gen 1 Type-A ports for connecting to different peripheral devices.
Thus the device can connect to different types of peripheral devices, with faster connectivity speeds as USB 3.1 ports provide a higher data rate than USB 2.0.
The station supports 2 displays, namely HDMI 2.0b female and DP 1.4. There are two Display Ports and only one HDMI port provided on the station. Thus the earlier versions of display devices are not supported by the docking station.
Main Differences Between WD15 and WD19
- WD15 uses a mini display female port for connecting to a computer system. WD19 uses a USB 3.1/3.2 Type-C male port for connecting to computer systems.
- WD15 provides a maximum data rate interface of 5GB/s. WD19 provides a maximum data rate interface of 10GB/s.
- WD15 can support 3 types of display devices. WD19 can support only 2 types of display devices.
- HDMI, VGA and Mini DP are the display systems supported by WD15. WD19 on the other hand supports HDMI, USB-C and DP 1.4 display systems.
- WD15 station weighs 422.42g, whereas WD19 is slightly heavier weighing at 585g.
The connectivity options available in laptops are limited to only a handful of ports. Thus for connecting more devices, external docking stations are used. Docking stations provide more connectivity options, without sacrificing the portability of laptops.
Both WD15 and WD19 are docking stations provided by Dell. The benefits and limitations in both these devices depend on the type of ports provided in the devices.
WD15 is compatible with older devices as well, as it is provided with ports that support older displays as well as peripheral devices.
WD19 is designed with connectivity options for most new devices. Thus, the ports provided in Wd19 can support newer versions of display and peripheral devices than the earlier versions.
The connectivity speeds of the docking stations are also different, as WD19 is faster than WD15 with its higher max data rate interface.
