★★★ Become experts of memory cards:
There are many situations of confusion regarding the use of memory cards. We are trying to solve the illusion of this small electronic device:
A memory card known as a memory memory card or solid state flash memory data storage is an electronic device that collects digital content. Nowadays it is used in many electronic devices such as mobile phones, digital cameras, music players and video games.
Digital changes recorded in it can be erased, re-organized and necessary changes can be made. This memory card differs in size, type from the pen drive that can be connected to a computer, a laptop, and a fixed location for the device in which it is used.
In the tech world, this is called a non-volatile SD card. SD means secure digital and non-volatile means that it does not need any external power source for its memory.
★★★ Three Kinds of Cards:
There are three types of memory cards. These are: SD, SDHC and SDXC
★★★ SD:
1. It is considered the first generation of memory cards. The thickness of this card is usually 2.1 millimeters and its maximum capacity is 2 GB.
2. Such memory cards come in three days. The first is the original SD, which fits directly into the groove. The other two come in the same small size, called MiniSD, MicroSD. They can be placed in the respective grooves with the help of an adapter.
3. SD cards are commonly used in personal computers, video cameras, digital cameras and similar large-sized electronic devices, while miniSD, microSD are used in small devices such as mobile, tablet.
★★★ SDHC:
The second generation memory card came in 2006, called SDHC. SDHC card means secure digital high capacity card. In size, they are similar to SD cards, but they have capacities from 4 GB to 32 GB. Of these, even smaller cards of smaller size are called microSD.
★★★ SDXC:
The third generation of memory cards came in 2009, called SDXC. SDXC stands for Secure Digital Extended Capacity. Their capacities range from 48GB to 2TB. (Practically still only 128GB capacity is available to the general public. Its small size is microSD only)
Now their UHS (Ultra High Speed Bus) and SDIO (Secure Digital Input Output) formats have also come. Memory cards with UHS 1 and UHS 3 formats have also come, which are used in most commercial devices.
★★★ Memory card speed:
Memory card speed is an important feature. This is measured by the speed at which a digital information like a photo can be captured or removed in a memory card. Many times you may have noticed that the camera takes too much time while saving a photo, prompting busyness or interrupts repeatedly while watching a video. Actually, every device with a memory card is made for a particular speed card. If you have a low-speed memory card, then it will not be able to give quick results.
Most of us do not pay any special attention to it. Often, people get 8GB / 16GB cards in a device made for memory cards up to 16GB, but do not pay attention to the speed of the card. So next time if you feel that your camera is taking too much time to store the photo after taking it or if the camcorder is not working properly for a video, then it is better to first check the memory card speed, Depending on the device or not.
Memory card has class 2 slowest and class 10 fastest speed. Now if the capacity of your camera is of a Class 4 memory card, then it is prudent to use a Class 4 memory card. Use of high-speed cards does not matter, because the camera is not able to utilize the capacity of high-speed cards properly. The point to note is that as the speed of a card with the same storage capacity (eg 16GB) increases, its value will also increase.
★★★ How to Learn Card Speed:
The speed may be written in MB / sec on the card. If this is not the case, you can identify the speed of the card by markings on the card. 2 written in an incomplete circle on the card means class 2, which will give a speed of at least 2 MB / sec.
Similarly, 4, 6, 10 means class 4, class 6 and class 10, which will give a speed of at least 4, 6 and 10 MB / sec. Having 1 or 3 written inside the u like sign will give an expectation of at least 10 and 30 MB / sec.
★★★ Memory card protection:
1. Many times we accidentally erase songs, photos or any data from memory card. By the time the mistake is realized, it is thought that the matter has gone wrong or there is no tampering of the memory card data.
2. There are many modern software to prevent counter-attack, which removes unwanted access to memory card data by any code or password. Some bliss also do this job well.
3. An easy way to avoid some kind of unknown mistake. There is a small piece of sliding on the side of the memory card, which is pushed to the lock position, then no data can be inserted, nor can it be removed in that card. It can be put back to normal to unlock.
★★★ A few more things:
1. If the memory card ever goes wrong then the problem is how to fix it. There are many software like SD card recovery tool for this.
2. If any data gets erased from the memory card, there are a lot of software like Undertalet 360, Rikuva to get it back.
3. Memory card tools, memory card manager can be used for various uses / tricks.
