Secure Digital Memory Card - The Ultimate Portable Storage Device

The heightened functionality, convenience and easy availability of portable storage devices have made them some of the most sought after hardware components in the present times. Owing to the extensive usage of mobiles phones and tablets, a demand for portable storage methods has increased. A secure digital memory card is the answer to this as it is not only small, but can hold in gigabytes of data as well.

Memory cards are sold in 3 forms: SD, mini SD and micro SD. Currently micro SD is largely used in mobile phones because it is very small and offers high transfer speed. The other advantage of these memory cards is that they consume very less energy to operate, thus making them the ideal choice for mobile devices.

Memory cards are classified as SD, SDHC and SDXC based on data holding capacity. SD is the basic version and not much in use currently. SDHC stands for Secure Digital High Capacity which can hold data up to 32 GB. SDXC stands for Secure Digital Extended Capacity which can theoretically hold data up to 1 TB. Other features of memory cards are write protection and password lock.

A 32 MB SmartMedia card is a type of flash memory card which was extensively used in digital music players, cameras and voice recorders until the arrival of Secure Digital Memory Card. The main limitation of the 32 MB SmartMedia card was its memory holding capacity. Although it was brought in as a successor to floppy disk, it couldn’t capitalize on the success. It was clearly out fashioned by SD cards as they could hold data up to 1 GB which was way higher then what a multimedia card could store. Therefore, 32 MB SmartMedia card is not much used in current systems.

The current trend in the SC card market is micro SD card as it is very small and power efficient. However, there are some devices which don’t support a micro SD card directly such as cameras and music players. For that purpose, you can use a 16GB Secure Digital Card Adapter. This is basically an extension such that the micro as well as mini SD cards can be used with incompatible devices. The construction of the 16GB Secure Digital Card Adapter is such that you can easily put the micro SD card in it which can then be used with a camera or laptop.

Before using a 16GB Secure Digital Card Adapter, make sure you are entering the right micro SD or mini SD card in it as some are exclusively manufactured for only certain memory cards. Secure Digital Memory Card has varying reading and writing speeds depending on the class it belongs to. Class 2, 4 and 6 are the standards for SD card data transfer speed. The speed increases as the class number increases. The SDXC card can support data transfer up to 400 MB/sec. So, choose your memory card well and use it to optimize the efficiency of your electronic gadgets. An efficient card is a highly functional part of electronic devices.

Author’s bio: Owing to its small size and memory protection management, a Secure Digital Memory Card is the best option for your mobile device. 32MB SmartMedia card was in demand in the 1990’s but as of now, the 16GB Secure Digital Card Adapter is the preferred choice.
