With the expansion of portable media in modern lifestyles, huge things are transformed and are minimized in size to accommodate them. With the minimization of devices equipments used are indulged to more reduction of size. Like the camera’s, earlier these devices were very large in size like big boxes, but now they are even smaller than our palm. The photo film is now replaced by the digital memory storage devices. The digital cameras used these days are very easy to use and handle. This easiness is only due digitization of memory storage space. Otherwise it was complicated to deal with the photo films. SD cards or the secure data cards are used nowadays for memory storage in cameras. The photographs clicked by using that digital camera get stored in sd card.
About SD card:
Use of this storage device is quite easy and as the name indicates, secures digital, it keeps the data secured. Basically what this Secure Digital is? It is an amazing device memory storage device having non volatile memory mainly used for portable devices like digital cameras, GPS navigation devices, mobile phones, tablet computers and others. The secure digital standard is prepared and maintained by the Secure Digital Standard Card Association (SDA).
There are many types of SD cards specified in many ways according to the physical size of these cards they are specified according to their size or appearance. Mainly these devices are available in three sizes these are mini sd card, micro sd card and sd card. The Micro sized SD card is smallest of them all and is named as microSD, microSDHC, microSDXC.
The miniSD card and the microSD card are originally named as TransFlash or TF memory devices, these small cards can be used in larger slots in computer by using the passive adapter. The card names SDHC that means Secure Digital High Capacity, SDXC means Secure Digital eXtended Capacity and the SDIO is the Secure Digital Input Output. These cards are only capable of input output functions in the host devices. SDHC and SDSC cards have some compatibility issues like the redefinition of card-specific data register or CSD register and the fact that SDHC card is preformatted using FAT32 file system. After their mutual compatibility they must be compatible with the operating system on which will be used in future. The host operating systems like Mac (Apple Mac OS X supports SDXC cards, exFAT is supported by Mac OS X Snow Leaopard and the later versions are supported by the OS X Lion), Windows (every version up to windows 7 and 8), windows server 2003 SP2 or SP3 with KB955704 and the Windows CE6.0 and above also support these sd card formats.
Speed of data storage in these memory storage devices is also very good. The applications like the video recording in the camcorders and digital cameras requires sustained write throughput and if the device doesn’t perform satisfactory it means that the speed is below desired speed.
Similar to USB flash memory card, the SD or secure digital card from the SD family is also block addressable storage device, from where a host device can read, write or edit the fixed size blocks by specifying their block numbers.
Different operating system supports different file formats and according to those files formats the specifications of secure digital cards also vary. Like the Mac OS SD cards are partitioned into GUID devices and can be formatted using HFS Plus system of files or can use the eXFAT file system. Beside this risk of reformatting of the storage device is also there. The reformatting of sd card with another file system format or again with the same file format decreases the life span of the sd card. Due to this storage speed is degraded to too much lower grade. Reformatting can lead to loss of data from the storage device. This is very problematic condition when the data from the sd card got lost accidently and finding how to get that back. Earlier it was impossible task to recover the lost data from the sd card but now it is possible.
The loss of data mainly depends upon the usage of device. If someone tries to reformat and forcefully use the wrong configuration of device with these memory chips, obviously they will create problem.
