How to choose a memory card (flash drive) for a smartphone

                                   Choosing a right flash drive

        The need to install flash-drive in a tablet, smartphone or any other device running Android, appears in most cases.

       The reason may be a budget model of the device, which does not have enough internal memory or increased user requests for the necessary space to store personal files. To understand which flash drive to choose for Android, you need to understand their types and characteristics.

                                        Types of flash drives

        After many attempts to create a reliable and high-speed storage medium, Flash memory was developed, which completely replaced outdated diskettes and optical discs. Modern drives can be divided into two groups, each of which can be a good option for use with Android:

                                              USB drive 

The most common form that is used in the daily work of millions of people. High data processing speed, miniature size, and mobility make it an indispensable tool. You connect flash drive to a computer, tablet or smartphone via an external USB port. In some cases, an adapter cable is required.

USB Flash drive. The best media option for all mobile devices running Android, as well as any other operating system. The usb flash drive has a miniature size that allows you to place it in the gadget, without having to disconnect. The data exchange rate of these media is very high.

For gadgets, the option with a flash card will be much more practical. They have this feature implemented using the appropriate connector. Further selection will depend on the characteristics of the memory card itself and the capabilities of the device.

                                   Memory Card Specifications

          All modern digital devices have a number of characteristics that determine the possibility of using flash memory. Most modern gadgets use SD cards. But here the choice is not as simple as it seems. It is necessary to choose the right flash drive for the main characteristics:

                                              Form factor 

The first criterion that determines the ability to connect the card to the gadget physically. There are three possible versions: SD, MiniSD, and MicroSD.

Volume. The choice depends on the requirements of the user. Manufacturers offer a large assortment of flash drives from 1 GB to 2 TB. For ease of selection, SD cards are divided into groups: SD 1.0, SD 1.1, SDHC, SDXC.

The class. The quality of the memory and the speed of data processing (read/write) depend on the class of the flash card (read here). Sometimes this parameter is replaced by a multiplier that corresponds to a particular class.

Having studied all the characteristics, you can easily understand which flash drive you need to choose for a smartphone. But here there are some limitations that are associated with the technical capabilities of the device.

                        Choosing a flash drive for a smartphone

         Not always the user can get what he wants. When buying a memory card for your gadget, you must consider its technical features:

Support flash cards of a certain size. Most devices have limited memory usage. These characteristics can be found in the technical passport. Many devices allow you to expand the volume to 64 GB, rarely possible use of 128 GB.

Battery power. Flash drives with large amounts of memory consume significantly more power so that the smartphone will be discharged faster. To balance the flow, you need to stay on the optimal size of the flash drive. You should not purchase 64 GB if you use a maximum of 8 GB.

To purchase any product must be approached responsibly. Selection of an appropriate memory card not only saves the budget but also opens up new opportunities for your beloved smartphone.

How to repair a USB flash drive

        A flash drive is a flash-based memory device. It is very convenient for transferring and storing sufficiently large volumes of information. They are used by everyone and everywhere. That is why most users have a lot of questions caused by malfunctioning of the flash drives. 

        All problems associated with the failure of flash drives are divided into physical and logical. Physical issues include mechanical damage, damage caused by liquids, electrostatic discharges, overheating, mechanical problems, etc., logical problems include a violation of the file structure due to incorrect use.

        Accordingly, the method of repairing a flash drive depends on the type of damage.

                          Mechanical problems of the flash drives

Damage to the flash drive case may occur as a result of an accidental fall a flash drive to the ground or any other mechanical incident. In this case, the USB connector may be bent, and the external case may be broken or rumpled. If this does not damage the memory chip that is inside, then data recovery from the flash drive is possible, but its full repair, most likely not. However, if even with a broken case the flash drive is detected by a computer, it means that it can be easily exploited further without additional repair.

Damage caused by spilled liquids may occur by accident with any flash drive. For example, when you had your flash drive was in the pocket during the rain or because you accidentally washed your flash drive in a washing machine, or it simply turned out to be in a puddle of spilled coffee. In this case, trying to save your flash drive you must leave it in a warm, dry place for a couple of days. Inserting your wet flash drive into the computer can cause contact closure due to the water and, consequently, data loss. If it is just wet on the outside, then it is likely to dry again and work properly again. If not, you need to check the memory chip. If it is intact, then information recovery is possible, if not, then it is better to seek the help of professionals.

Electric shock damage can lead to irreversible consequences, both for flash drives and for computers. A common cause is the confused polarity of the USB port power contacts that occurred during assembly. As a result, the contacts burn out. Another reason is a bad UPS, which can create insufficient or excessive voltage. And either the flash drive does not work, or it burns out. So, in the future, it can happen with the hard drive. The most common cause is ungrounded outlets. In this case, a static charge on the computer case is activated when the metal case of the USB flash drive is brought up. The consequences are usually dependent on the health of the chip, and the user will need to replace the defective parts.

Damage due to the natural course of time cannot also be excluded. 

Loss of flash drive. In this case, the data recovery will fail, but it is possible to protect it. There are many programs and mechanical methods that impede access to outside users.

       In the case of almost all mechanical issues, it is important that the memory chip remains intact. Then you can extract your information from it with the help of special software. 

                                Logical problems of the flash drives

Incorrect use. In this case, damage occurs when USB flash drive is not properly extracted from the USB port during recording or formatting. If after that the information from the flash drive can't be read, then sometimes it can be restored if you download the program for repairing flash drives: images - PhotoRescue, data - EasyRecovery.

Temporary wear. It can be determined by the increased time of reading information. In this case, the file structure is damaged, so you should copy any information you can to the other carrier, and then flash drive should be deeply formatted.

                                               Conclusion
