Types Of SD Cards

In today’s modern age, every user using a smartphone and digital camera is familiar with the SD memory card i.e. secure digital memory card. As the devices are getting better and better, so is the digital card in its capacity and speed are happening. SD cards can be divided according to their size, capacity and speed.


Types by size

SD Memory Cards i.e. Secure Digital Memory Cards are available in full size, standard size and mini size.


Full size SD card cannot be used in all devices. Medium size SD cards are mostly used in mobiles. The use of mini SD card used to be very high but now it has decreased a lot but still many people like to use mini card.


Types by capacity

There are three types of SD cards in terms of capacity, SD, SDHC and SDXC


Normal SD card capacity is limited to 2 GB. SDHC ie Secure Digital High Capacity Card has a capacity of up to 32 GB. SDXC (Extended Capacity Card) can theoretically have a capacity of up to 2 terabytes. To date, no company has been able to create an XC card limit of up to 2 terabytes.

Not all memory cards can be used on all devices.

A device that supports a standard SD card only uses a standard SD card. In addition to HC, an SD card can also be inserted into the device that supports the HC card. SD and HC cards can also be used in XC devices.


Types in terms of speed

There are also many types or classes of cards in terms of data reading and writing on the card.

These are written in an incomplete circle on the top of the class card. These are classes 2, 4, 6, 10, UHS1 and UHS3. The class written on the card indicates the speed of data transfer in the card. The Class 2 card means that data can be transferred to this card at a speed of 2 megabytes per second. In contrast, UHS (Ultra High Speed) class data transfer speeds can be up to 320 megabytes per second.

Prices for cards with the same capacity can vary greatly depending on the speed of the SD card and the company.



Which memory card is best for you?

If you only want to use the memory card as a storage device, then a Class 4 card is better. Class 6 cards are better for HD recording in mobile.

Using a card with less than that, the HD recording will not be stored properly on the card. Similarly, if users think that they will also save 4K recordings and RAW images, then UHS1 or UHS3 card is better. Class 6 and above storage cards are also ideal for general storage in DSLRs and point-and-shoot.

Users can also use the application by installing it in the memory card in the new mobile operating system. In this case, users should use a Class 10 card.
