Kingston o ers a wide range

of Secure Digital Cards

7.3 SECURE DIGITAL CARDS (SD, SDHC, miniSDHC, microSD, microSDHC)

Secure Digital, introduced in late 2001, is a second-generation derivative of the

MultiMediaCard (MMC) standard (see section 7.4).

The Secure Digital format includes several important technological advancements over

MMC. These include the addition of cryptographic security protection for copyrighted

data/music. The SD Card Association, of which Kingston is an executive member, sets the

speci cations for Secure Digital cards.

SD cards are slightly thicker than the original MMC cards. This means that devices designedto

support SD cards may also accept MMC cards (if the host device is not strictly limited to SD

media for SD copy protection management features). However, devices exclusively designed

for MMC cards will not support the thicker SD cards at this time.

Kingston o ers standard SD cards as well as high-performance Elite Pro and Ultimate SD

cards. Secure Digital High Capacity (SDHC), starting at 4GB, o ers larger volume data

storage and optimized recording performance with support for FAT 32  le formats. In

addition, Kingston’s SDHC cards use new speed “class” ratings known as Class 2, 4 and 6

that deliver a minimum data transfer rate for optimum performance with SDHC devices.

Although identical in size to today’s standard SD card, the new SDHC cards are designed

di erently and are only recognized by SDHC host devices. To ensure compatibility, look for

the SDHC logo on cards and host devices (cameras, camcorders, etc.).

miniSD (SDM) and microSD (SDC) are the mobile platform form factors of the SD card for

use in cell phones and other portable devices. miniSD and microSD are a fraction of the size

of a standard SD card and, when used with the supplied Kingston adapter, can be used in

standard SD device slots (for example, in Flash media readers).

Starting at 4GB, miniSDHC cards o er higher storage capacity for high-resolution multimedia

content and support more demanding data transfer rates. Kingston’s miniSDHC cards use

new speed “class” ratings known as Class 2, 4 and 6 that guarantee a minimum data transfer

rate for optimum performance with devices that use miniSDHC storage devices. Identical in

size to today’s standard miniSD card, the new miniSDHC cards are designed di erently and

are only recognized by miniSDHC host devices.

microSDHC cards o er higher storage for more music, more videos, more pictures, more

games — more of everything for today’s mobile world. The microSDHC card allows users to

maximize storage for today’s revolutionary mobile devices.
