An SD card slot is necessary for a computer, especially if you have a digital camera that stores its data on SD cards. But not all computers have slots for these cards. Some computers may focus on wireless transfers, while others might focus on implementing more USB ports or other connections outside the SD card. Many computers also use USB Type C ports to help them directly link with smartphones, tablets, cameras, and other devices that use this connection standard.

You might be asking, “There is no SD card slot on my PC, and I need something that can read my data. What can I do here? To save space and because of the lack of popularity, many computer companies have done away with SD card readers being directly attached to their computers. Although beneficial in some sense, this can be a pain for the millions of people who still use SD Cards. The great news is that there’s an assortment of SD card adapters you can utilize for your computing needs today. These include adapters you can plug into a USB port in your computer.


The SD card adapters you’ll read about in this guide link to your computer through a USB connection. You will insert the SD card into the device and then plug that item into your USB port.

You can find USB 2.0, 3.0, and 3.1 models. Each one has a different transfer speed, with the USB 3.1 being the fastest:

  • USB 2.0: 480 Mbps (megabits per second)
  • USB 3.0: 4,800 Mbps
  • USB 3.1: 10,000 Mbps

The USB 3.0 and 3.1 standards produce faster data transfer speeds, plus they can send and receive data at the same time. A USB 2.0 device can only send or receive data at once and cannot simultaneously handle both.

A USB 3.0 or 3.1 device will also require a USB port that can accept this connection standard. USB 3.0 and 3.1 items produce a higher current than USB 2.0 ones. While a USB 3.0 item can work on a USB 2.0 port, it will only generate speeds akin to what you’d get from a USB 2.0 device.

You can visually identify which USB standard something uses by the color block inside the port. USB 2.0 devices have a black block, while that block is blue for USB 3.0 items. USB 3.1 ports have a red block.


Many of the devices you’ll also read about here feature USB Type C or USB-C ports. While the Type A port is the one you would associate with the most when using a USB device, the Type C port is smaller in size.

The USB-C port has an oval shape that makes it look like a micro-USB or Type B connector. But the USB-C port is flippable, meaning you can insert the plug on either side. The connection is similar to what many tablets, smartphones, and cameras utilize for data transfer and battery charging needs.

If you need an SD Adapter, but also need more inputs on your laptop or PC, then you may want to invest in a Docking station. Check out our article about how to add a docking station to your computer.
