Computer Memory Card Readers and Adapters

Memory cards, which are also called flash cards and memory cartridges, are a type of portable data storage. The storage is non-volatile, and that persistence and portability make it an ideal storage solution for smartphones, tablets, and many other portable gadgets. Readers and adapters are what make these memory sticks usable across Windows PCs, laptops, Android devices, and more.
What is a memory card reader?
A card reader is a device that accepts compact flash media for reading and writing. Broadly, there are two kinds of readers: internal and external. Examples of internal card readers include the micro SD slot on a tablet, a memory card slot on a camera, or an SD card slot on a laptop. External readers may be standalone or part of a hub and often connect to the computer or other device via USB.
What is a memory card adapter?
An adapter is often like a cross between an external and internal memory card reader. A card reader that connects to a computer via a USB port is an external solution. A reader that accepts micro SD cards by attaching to an internal SD card reader is an adapter. Both are interfacing, but the difference is that the second solution is acting as pass-through to an internal mechanism.

Do I need a different reader for each card type?
It depends. Some slots have a versatile connector that can, for instance, accept either SD or micro SD. Others accept only one card type or some but not others. Hubs are often quite versatile and convenient because they can feature multiple memory card readers, USB ports, and other connections in a form compact enough to be portable.
What card reader types are available?
Many memory stick standards have been developed over the years, and certainly, many more will be introduced in the years to come as the technology and standards advance. Some of the formats that have been prevalent over the years include:
- SD: SDSC stands for Secure Digital Standard Capacity. These cards feature a write-protect notch and are 2.1 millimeters thick.
- SDHC: The Secure Digital High Capacity format built on SD by supporting capacities up to 32 GB.
- SDXC: The Secure Digital eXtended Capacity format expands the base SD card format even more by supporting capacities up to 2 TB.
- Micro SD: This is a form factor extension to SD that allows for smaller physical cards. SDHC and SDXC are supported as well.
