Frequently Asked Questions

What different types of memory cards are there?

Technology is continually evolving, and it can be difficult to keep up with the ever changing types of data storage cards. The most common memory cards are SD cards, which stands for “secure digital.” SD cards measure 32mm x 24 mm. When the SD card name is followed by letters, these indicate its storage capacity. Standard SD cards hold up to 4 GB. The next step up is high capacity SDHC cards which hold between 4 GB and 64 GB, while extended capacity SDXC cards hold more than 64 GB. Micro SD cards use this same secure digital technology, but are smaller at only 15mm x 11mm, and are used in some phones.

Beyond SD cards, there are some other commonly used memory cards. A larger card used in digital cameras is the compact flash card, which measures 42.8mm x 36.4mm. Alternatively, the MS card, or Memory Stick card is used only in Sony electronics. 

What are the different types of USBs?

There are two ways in which USBs are categorized: by speed, and by physical connector shape. The number after USB indicates its speed of data transfer. USB 2.0 can transfer 480 megabytes per second (Mbps), and USB 3.0 is much faster, with a speed of 4.8 Gbps. This is a significant difference in speed, because USB 3.0 is actually 10 times faster than USB 2.0. 

The letter after USB indicates the shape of the connector. The most common USB ports are USB A. These are the USBs you’re used to seeing in computers, flash drives, inputs in car stereos, and more. While USB A is most common, USB B connections are slightly less abundant, but still familiar to most. USB B connectors are generally used for peripherals such as a printer or hub, and are square in shape. Finally, USB C is a new style that can deliver more power and efficiency. A USB C connection is smaller than USB A size, and is thinner. Another benefit of USB C connectors is that they can be flipped over and are fully reversible, unlike USB A connectors, which have a right side up and can only plug in one way. You’ll find USB C connectors on many newer devices. Lastly, another common USB connection shape is the micro USB, which is the connection port found on most Android phones and devices.
