Computer Memory Card Readers & Adapters
Memory Card Readers and Adapters for Computers
Memory cards, commonly known as flash cards or memory cartridges, are portable data storage devices. The storage is non-volatile, which makes it a great storage solution for smartphones, tablets, and a variety of other portable devices. These memory sticks can be used on Windows PCs, laptops, Android devices, and more thanks to readers and adapters.
What is the purpose of a memory card reader?
A card reader is a device that reads and writes to compact flash memory. Internal and exterior readers are the two types of readers. Micro SD slots on tablets, memory card slots on cameras, and SD card slots on laptops are all examples of internal card readers. External readers can be stand-alone or part of a hub, and they often connect to a computer or another device through USB.
What is the purpose of a memory card adapter?
A memory card adapter is a hybrid of an external and internal memory card reader. An external solution is a card reader that connects to a computer via a USB port. An adapter is a reader that accepts micro SD cards by connecting to an internal SD card reader. Both solutions interface, but the second acts as a pass-through to an internal mechanism.
Do I need a separate reader for each type of card?
It is debatable. Some slots contain a flexible connector that can accommodate either SD or mini SD cards. Others just accept one sort of card, or some but not all. Hubs are useful and adaptable because they can accommodate many memory card readers, USB ports, and other connections in a small, portable package.
What types of card readers are available?
Many memory stick standards have been produced throughout the years, and as technology and standards evolve, many more will undoubtedly be released in the future. The following are some of the popular formats over the years:
- Secure Digital Standard Capacity (SDSC) stands for Secure Digital Standard Capacity. These cards are 2.1 millimeters thick and have a write-protect notch.
- SDHC stands for Secure Digital High Capacity and supports capacities of up to 32 GB.
- SDXC: The Secure Digital eXtended Capacity format expands on the fundamental SD card format by allowing for capacities of up to 2 TB.
- Micro SD is an SD form factor expansion that enables smaller physical cards. SDHC and SDXC cards are also supported.
What kind of USB connections do reader hubs have?
- USB 2.0: The effective throughput of this USB connection is 35 MB/s.
- USB 3.0: This SuperSpeed implementation has a 3.2 Gbit/s effective throughput.
- USB-C: For easier use, this USB version contains a reversible plug.
- Micro USB: On portable devices, this smaller physical connection is prevalent.
- USB OTG: On-the-Go connections can be used to host USB devices.
