If you plan to move files in and out of your portable device (tablet or smart phone), please consider using a MicroUSB card reader, such as Leef Access.
Avoid buying memory cards from suppliers with little feedback on the auction site, as these drives may be fake. All of the vendors listed below are tried and trusted.
SD cards with 128GB or more capacity are often cheaper because users can usually use 64GB which matches the maximum supported capacity of most portable devices. In general, the cost of a microSD card with an adapter is lower than that of an equivalent SD card.
Please note that all capacity may be much smaller than the specified capacity when formatting.
SD cards are usually divided into several categories to provide an overview of the expected minimum performance. Level 4 cards are guaranteed to provide at least 4MBps, while Level 10 is guaranteed to exceed 10MBp.
Similarly, many suppliers report their speed at the "x" level, which is a multiple of 150 KBps (the reading speed of a standard CDROM drive). The 100x card can provide speeds in excess of 14MBps.
If you are planning to purchase a microSD card just to store the data, Please don't keen on cheap one because the microSD with real value is worth choosing.
