Cheap SD Memory Cards - The Basics

Cheap SD Memory Cards - The Basics
by Helen Charleston

In 1999, Mitsubishi and Toshiba put forth a collaborative attempt to create a convenient means to store computer files for camcorders and computers. The result was the inexpensive SD Memory Card.

These SD (Secure Digital) cards all but replaced the Multimedia Card (MMC), having typically and noticeably faster transfer rates as well as a high-density storage capacity. The standard transfer rate for the cheap SD memory card is six times faster than the typical CD-ROM, with a speed expending at 66x (1.01 specification).

The higher speed SD memory card, though, possesses a 133x speed (1.1 specification), enabling data transfer of complex audio/visual files to proceed and save in mere microseconds. The average data transfer rate provides the capability for these files to record everything at the same time and immediately.

The function that really makes these cheap SD memory cards so much better than the old MultiMedia Cards is the storage space. Not only is storage vaster, but the SD memory cards are available in a multitude of different capacities: 900kB/s ands 10 MB/s,16 MB/s, 32 MB/s, 64 MB/s, 128 MB/s, 256 MB/s, 512 MB/s, 1 GB, 2 GB/s, 4 GB/s, 6 GB/s, and even 8 GB/s, which is so huge that it can hold a library of movies and considerably more!

The cheap SD memory cards usually require a card reader or adapter to act as a connecter to a central processor of some sort (computer, camcorder, etc.), but are even designed to utilize USB ports. Many modern electronic devices are created with a SD memory function or a port especially made for the SD memory card.

That such a gadget is (relatively) inexpensive is yet another advantage of the SD memory card. The prices are as varied as the storage capacity, but lower costs provide an incentive for those who are looking for a sophisticated, high calibre product.

Prices range anywhere from $10.95 for the 128 MB/s to $12-$15.00 for the 256 MB/s and under $20 for the 512 MB/s. The prices for the 1 GBs differ, but they typically fall under $60. The more inexpensive brands, such as Corsair and Kingston, average between $35 and $45, whereas the more well-known brands (SunDisk and Lexar) range from $50 to $60. The 2 GB SD memory cards are around $100 or slightly more.

For those gung ho audio/visual enthusiasts who want to build extensive archives of files, or for those who have many small simple Word doc files, the cheap SD memory card is the best device to use.

The compatibility of SD Memory Card with digital equipments

The compatibility of SD Memory Card with digital equipments
by Shawn Paul

The SD memory cards known as the "Secure Digital" first began as miniature cards. Afterwards the new and advanced form of the SD memory card SDIO "Secure Digital Input/output" was introduced into the market. The SDA "Secure Digital Association" included new features and technology to the SD memory cards. The SDA included new varieties of card functions. These new card functions included wireless "Local Area Network LAN" devices, cell phones, GPS receiver, digital video camera etc. The memory card readers that were used in the Secure Digital devices connected to the Universal Serial Bus (USB). The Windows Operating System detects and manages the SD (Secure Digital) memory cards through the driver called the (USB) Universal Serial Bus mass storage. The (SD) Secure Digital host controllers are supported by the Operating System. The Operating System connects the host controller SD to the Peripheral Component Interconnect (PCI) bus. When the SD-host controller is detected by the operating system, the "SD Secure Digital bus driver" is loaded by the operating system OS. When the SD card is inserted by the user, the windows Operating system loads two drivers the "Storage mini-port" and the "SD Secure Digital Storage Class". These two drivers are loaded on top of "Bus driver" by the Windows Operating System. On the other hand if the SD memory card of a different function like the wireless Local Area Network (LAN) or the Global Positioning System is inserted by the user, then the Windows Operating System loads the driver that is supplied by the vendor. It is necessary that both the vendor supplied and the native drivers in the (SD) Secure Digital stack communicate with "Secure Digital Bus". The device drivers call the routines to communication with the "Secure Digital Bus". These routines are called in the static "Secure Digital Bus library". When the SD Secure Digital drivers compile, it is necessary that they link to the "Secure Digital SD Bus library". There are some limitations for the SD device drivers. The "Host Controller Register" is not directly accessible by the Secure Digital device drivers. The SD device drivers call the routines of "Secure Digital Library". Then the Secure Digital Library forwards the Secure Digital commands to "Host Controller". Music can be stored in the Flash Memory card and it is most advantageous than storing it in the Hard drives.
