Memory Sticks

Flash memory for data and photos

The term “memory stick” is a somewhat vague categorization that may refer to one of several data storage devices. The “memory stick” title can be applied either to data storage products like Sony memory sticks or flash memory cards, which are used in tandem with digital cameras, or to USB flash drives for powerful portable data storage.

Both types utilize non-volatile flash memory to store data. This is done for a variety of reasons. As a constant power supply is not needed to store and maintain data, these technologies are perfect for use with devices that run on batteries or don’t have a consistent electrical input. Flash memory sticks are also extremely durable, and maintain their memory and data retention capabilities even under extremely adverse conditions.

Sony Memory Sticks

Sony memory sticks can store up to 16 GB, and are theoretically capable of providing as much as 2 terabytes of data storage. When they were originally released in October, 1998, they had storage capacities of 128 MB. The original lineup included the Memory Stick Duo in addition to the 128 MB memory sticks. The Duo was essentially a smaller version of the standard memory sticks which were available at the time.

Typically used in portable consumer electronics devices like digital cameras, camcorders, PDAs and cell phones, Sony memory sticks are also compatible with some personal computers. The Sony Vaio line of personal computers, for example, has standard issue slots for removable flash memory cards.

USB Memory Sticks

USB memory sticks, commonly referred to as flash drives or thumb drives, are devices that are compatible with the universal serial bus on a computer and can store information for easy transfer to another machine. However, the term “flash drive” is a bit of a misnomer, as these products do not contain any moving parts.

USB memory sticks can:

• Store any type of file
• Interface with a wide range of machines via the USB port
• Offer easy storage of up to 128 GB of data or more
• Access stored information and files faster than an optical drive, while holding a larger amount of data in a smaller and more compact package

While there are many useful applications for USB flash memory sticks, they do have their limitations. They have a higher price-to-unit ratio for data storage, and many models can be easily damaged unless proper installation and removal methods are used when connecting the device to a host computer.

Both memory cards and USB flash drives are practical solutions to memory and data storage challenges. The two formats have a lot in common, but are put to different uses. In the coming years, engineers will no doubt push the capabilities of both formats much further, while driving prices even lower than where they are now.
