Recognizing the Types and Variety of Memory Cards

The need for storing large data files to make the memory card (memory card) so that basic needs can not be separated. Especially for local phones will usually minimal internal memory, memory card is mandatory items that must exist. But did you know that it turned from a wide range of memory cards in circulation appears to have different types and specifications that make it uniquely different from each other.

This difference was not only limited to the brand or quality of materials, but also affect the quality of the performance that will surely be felt later on when it is used in your mobile device. Therefore, Paseban will discuss the various types of memory cards for your convenience in identifying and know your needs before buying a memory card for your mobile device.

Shape Memory Cards

The first thing to note is that the shapes of the various memory cards on the market. However, other types of cards include:

   1. Standard size SD cards, SD cards are most commonly used for digital cameras or DSLR but not used for mobile devices and tablets of the large size of the memory. Its size is about 32 x 24 x 2.1 mm.
   2. Mini SD, before this type of memory is widely used in mobile phones, but lately very rarely found in the latest mobile phones. The size is 21.5 x 20 x 1.4 mm.
   3. MicroSD, with the smallest size that is approximately 15 x11 1 mm. This makes the memory size as the memory is now commonly used for mobile phones, tablets and digital cameras.

Specifications Memory Card

Currently there are 3 types of SD memory cards in circulation which is the type SD, SDHC, and SDXC. The main difference lies in three storage capacities of the three cards. The comparison is as follows:

   1. Card type SD (Secure Digital) storage of data contain only limited to the size of 2 GB.
   2. Card type SDHC (Secure Digital High Capacity), this type of data can menampng up to size 32 GB.
   3. Card types SDXC (Secure Digital Extended Capacity), this type can load data from 32GB sizes up to 2 TB.

SDHC is a new standard developed by the SD Card Association. SD Card using a standard file format called FAT 16 which supports capacities up to 2 GB. While SDHC cards use the new file format called FAT32 which has a maximum capacity of 32 GB. While SDXC is the next generation of memory cards. SDXC memory cards is the first storage device in the world that meet the new specifications of the SD memory card version 3.00, which maksmum kecepata write up to 35 MB / s and read speeds up to 60 MB / s.

Speed ​​Memory Card

Speed ​​performance of the memory card becomes differentiator was enough. The speed of the memory card itself is classified by code numbers. Currently for non-UHS memory is divided into 4 different classes. While UHS memory cards of only one class speed. To categorize them as below:

A. Class 2: minimum write speed of 2 MB / s
B. Class 4: minimum write speed of 4 MB / s
C. Class 6: minimum write speed of 6 Mb / s
D. Class 10: a minimum write speed of 10 Mb / s
For UHS-1: a minimum write speed of 10 Mb / s.

It could be a memory card manufacturer provides data transfer rate is higher than the minimum. But often it is the speed meksimal to read (read) and write (write). The figure here is the maximum speed of data transfer is achieved by yan capable card with optimum connection conditions.

The difference in the specifications of the memory card itself has a variety of purposes, for example, is targeting a higher market. For example, for a smart phone with a high specification, this can work using a standard memory card, but if you want to use the mobile phone to run applications that are quite heavy, it is better to use a memory card with high speed so that applications can run smoothly.
