In the digital age, more than half of everything we do is digitally-based. Some of these include shopping, watching movies and shows, and playing video games. We can do this through computers and handheld devices such as smartphones or tablets. As there are many things to do in the digital space, we must have spare memory in order to save as much as we can. This is where flash memory comes in.

Flash memory is also known as an SD card, or flash memory card. No single flash memory card is the same, as there are different types of it. With flash memory, it can be used as a spare memory to store more digital files. Flash memory is usually used in handheld devices, such as smartphones and tablets. However, other gadgets make use of flash memory as well, such as cameras. Computers and laptops can also make use of flash memory provided that the user has a card reader.

Below are the different types of SD cards, or flash memory.

SD Card

Secure Digital, or SD, is known as the basic format of flash memory. It does what you expect in a memory card, which is storing files. Files that can be stored in an SD card include photos, videos, digital music, and e-books, to name a few. An SD card can go up to 4GB worth of storage space. As this is the basic format of flash memory, this is a great starting point if you’re looking to use and utilize flash memory.

SDHC Card

SDHC stands for Secure Digital High Capacity. As the name implies, it’s the SD card with higher capacity. Like the SD card, it can also store photos, videos, and other digital files. Since the SDHC is a better SD card, the photos and videos that are stored are usually of higher quality. An SDHC card’s capacity starts from 8GB and can go up to 64GB worth of storage space. You should opt for an SDHC card if you want photos or videos with better quality.

SDXC Card

SDXC stands for Secure Digital Extended Capacity. Yet again, this is a better reworking of the SDHC Card. Like previous memory cards, you can store photos, videos, and other digital files. Photos and videos that are shot with an SDXC card have higher quality than those photos and videos shot with an SDHC card. As opposed to the previous types of SD cards, the storage capacity of the SDXC goes from beyond 64GB.

MicroSD Card

Micro Secure Digital or MicroSD, is another type of flash memory. As the name implies, it’s a smaller version of an SD card which measures only about the size of a fingernail (15mm x 11mm). A MicroSD’s storage capacity can go up to 4GB, which is the same as a regular SD card. For you to be able to access a MicroSD card, you will need a card reader. A card reader acts as an adapter of sorts for Micro memory cards.

MicroSDHC Card

This is the SDHC card, but in the same size as a MicroSD card. A MicroSDHC card’s capacity is the same as the SDHC card, which goes from 8GB to 64GB worth of storage space. Like the MicroSD card, you will need a card reader to be able to access a MicroSDHC card.
