SD Memory Card - What Is It And How Can It Help You?

By Mitchell Pierce  |   Submitted On October 12, 2010

If you are not a technology buff, learning about new things like digital cameras and all of these latest and greatest devices that are out on the market can be burdensome. If you have been researching or maybe just purchased a new digital camera, then you have probably purchased or looked into SD memory cards. This article will provide helpful information on what SD memory cards are and how they can help you with your electronic devices.

The "SD" actually stands for secure digital. The best way I can describe this memory card is that it is like a small cartridge that is inserted into a myriad of electronics devices. They are very small in size and the storage space can be huge. They are usually smaller than a US quarter and some of the cards I have seen can store up to 128 gigabytes. Obviously the more storage space means more room for more pictures to be taken or movies to be shot. There is actually an even smaller version called a micro SD card that is even smaller than a dime.

The types of devices that these types of memory cards are used in range from cell phones, digital cameras, video camcorders, printers, and many more. The basis for their existence is that, for example, some photography cameras no longer use actual film for taking the pictures and instead a digital photograph is taken. This digital image needs to be stored on a something because it is a file, just like other files on a computer. The SD card is the storage vessel that allows for the pictures, videos, or music, or whatever you are storing to be stored. One great feature is that these types of cards are compatible with a lot of different devices. I can take the SD memory card I have out of my camera and put in directly in my computer and browse the files. I can also store things on these little cards and transport information from work to home.

There are lots of different types of memory cards out there. Sony makes a different type of memory card called a memory stick. This type has a distinctly different shape and would not generally work in a device that uses an SD card. This is not true all of the time, due to some devices having multiple memory slots. These memory cards are very useful and can help anyone who needs room to store files. They can also be helpful if you need to share information with a friend and you can mail it to them because they are so small. they can also be used to transport information to and from work. I personally store pictures and music on my card. I recently purchased a digital video camcorder that runs completely off of these types of cards and does not use a tape at all. My entire music collection fits on one 8 gigabyte stick with all my photos and movie files also.

6 Benefits of Using USB Flash Drives

By Leo Eigenberg  |   Submitted On May 12, 2017

USB flash drives are a highly versatile and portable solution to transfer or store computer data. A great quality is the high durability because of the lack of moving parts. This means they are harder-wearing than alternatives like the hard drives. Here are a few of the major benefits of using the USB flash drives:


The USB flash drives are appreciated for their small size, which makes them really portable and easily attached to a key chain or slip into a pocket. Most of these storage devices are two or three inches in length. However, there are larger sizes, such as the novelty designs that are favored by a certain niche of buyers. Plus, the durability of this item also means it is more practical for carrying around.


The memory capacity of the USB flash drives is in the region of 1 to 128 GB. The 1 GB units are very cheap and a practical choice for light storage and simple file transfers. For those planning to back up a hard drive or run a program, the higher memory capacity is required. The drives with 32 GB or more are useful for the high load jobs. The largest size opens up plenty of data storage options, such as the ability to store music, movies, or photographs.

Transfer speed

The USB 3.0 device is rated to transfer data at a speed of 4.8 gigabytes per second. This is a quite impressive speed and better than other storage options such as the SD memory card which has a transfer speed of up to 312 MB per second.


The USB interface is the standard option to connect electronic or storage devices to all types of laptop or PC. Most desktops, laptops and netbooks are built with multiple ports for accepting USB devices. Also, there are the dual purpose USB flash drives that even have the ability to read memory cards.

Low power

With no motors or moving parts, the USB flash drives are built to consume very little power. They have a lot lower power consumption compared to hard-disk drives which have the writing and reading heads to operate.

Purpose made applications

There are plenty of programs and applications that are built to run directly from the USB flash drives. Software applications like games, web browsers, image editors and other office software can easily be booted directly from this type of portable drive.
