Top 12 Micro SD Memory Cards

Micro SD cards are the same memory cards on which every sector of the world depends. The very living nerve of the society used micro SD memory cards that are entirely built with the most tensile, compact, and high memory capacities. From DSLRs to cameras, Micro SD memory cards are used in a numerous host of electronic devices.

Micro SD Memory Cards Buying Guide

The memory card uses flash technology that saves your data even when not connected to an active power source. However, such memory cards are also useful in saving data like programming files, audios, videos, music, and much more. This tiny chip can work so many wonders that even the most significant professional might get amazed at the high usability and the range of applications this little chip holds and supports.

Types of memory card

Memory cards range from SD memory card, SDHC memory card, SDXC memory card, Micro SD memory card, microSDHC, microSDXC, and compact flashcards. Although in terms of memory, SD is the lowest and the slowest. The range gets higher and higher. The Micro SD card, as its name states, is small in size and can fit into super small places like the slot of your mobile phone. Micro SD cards can be used anywhere. However, they aren't compatible with DSLR cameras. DSLR cameras use compact flashcards for memory and storage.

Choosing the rate of transfer

 The transfer rate of various micro SD cards depends on the size, the making, and the technology used. For a 16 GB SD card, a regular HD video's transfer rate can be almost 9 Mbps. Each SD card has a specific speed class- that is, it can be categorized into four classes – C2, C4, C6, and C10. The C10 class Pendrive takes nearly 10 – 90 MB/sec to copy and 8k video at 60/120 fps. Some micro SD cards, namely SDHC and SDXC, support a mechanism called Ultra High Speed.

Ultra High-Speed feature

The Ultra High-Speed feature, or the UHS specification, provides a better transfer rate. The UHS technology, similar to the classwise orientation of the rate of transfer, has two forms. UHS -1 and UHS -2, the first-class- U1 provides the same speed as the C10 class. However, U2 gives almost three times more speed than C10 class, and with a 30 mb/s, the throughput is good. These help in transferring high quality 4K videos at faster rates. UHS supports two modes as well.

Duplex modes in U1 and U2

The U1 model work under half-duplex modes. That means one can send and receive data only one at a time. Only one process from the two will be commenced and completed. The U2 or the UHS-2 specification provides a full-duplex mode, under which data can be sent and received altogether. Currently, UHS-3 is under making as the device that supports the same has not been made yet.
