subject: Intelligently Engineered Sd And Sdhc Memory Cards By Sandisk [print this page] SanDisk manufactures highly durable, high quality SD (secure digital) memory cards whose storage capacity reaches up to 8 GB. SD memory card is a reliable storage medium used extensively in cellular phones, digital cameras etc. Highly durable SanDisk SD cards are the top most choice of the users. The increased capacity of SanDisk SD memory card benefits the consumers who require large storage capacity as they will not have to carry too many memory cards with them. The 1GB SD card can store MP3 audio (16 hours), MPEG4 video (9 hours) and 2000 images having resolution of 1600 x 1200 pixels.
Multiple physical partitions are enables in secure digital technology with the help of its reliable flexible partition mechanism. Therefore it allows it to accommodate varied data sources like multimedia content, applications, operating systems, and boot code along with customizable protection levels for each of the physical partition. Original equipment manufacturers (OEMs), content providers and mobile network operators have the flexibility and luxury to configure & control the embedded secure digital devices for different types of data and usage. Each physical partition can be configured separately along with different protection modes which include read & erase/write. Embedded SD (secure digital) devices each physical partition can also provides the flexibility of optional configuration that includes security of sensitive information (operator data, boot code etc.) and complete resistance to power failure. SD devices also offer the new advantageous technique of sleep mode that saves power. The SD embedded devices offer more advantageous features to its users that enable them to reduce the power consumption and customize their power needs. This advantageous technique helps to boost the battery life.
SanDisk has made advancements to the SD memory cards and introduced the new advanced SDHC (secure digital high capacity) memory cards whose recording capability ranges from 2GB to 8GB. SDHC memory cards developed by SanDisk are highly durable, efficient and are available at an affordable price. SanDisk SD memory cards are intelligently designed to deliver outstanding performance and outstanding data integrity.
There are 3 physical sizes of secure digital SD cards. The Micro SD card has size of 15 x11 x 1 mm and that of Mini SD memory card is 21.5mm x 20mm x 1.4mm. The size of standard secure digital card is 24 x 32 x 2.1mm, which is almost half the Compact Flash cards size. The SD cards have the capacity to record 2GB. The advanced and improved form of SD cards is the SDHC (SD high capacity).The file system of SD card format is FAT-16. In order to further elevate the storage capacity beyond 2 Gigabytes, the file system of SDHC card format was changed to FAT-32. Data can be read from the SD memory cards by both SDHC and SD reader. On the other hand data from the SDHC memory cards can only be read by the SDHC reader. SanDisk SDHC memory card format not only offers increased storage capacity but it also provides faster speed and flexibility to the consumers. SanDisk SDHC cards are highly compatible and are ideal for the advanced audio and video applications.
