Memory cards are available in a few significant types and are commonly used in electronics like a digital camera. Each type comes in different sizes.

Below are the most common types of memory cards.

1. CompactFlash (CF)

Launched in 1994 by SanDisk Corporation, the compact flash supports 3.3V and 5V operation with the option to switch in between both, unlike another flash memory card that can never operate at two voltages.

The manufacturer designed the CompactFlash card based on the standard of PCMCIA PC Card and supported a PCMCIA slot. The card has two different types that can accommodate several capacities:

Type I cards come at a 42.8mm x 36.4mm x 3.3 mm thickness

Type II cards feature a 42.8mm x 36.4mm x 5.5 mm thickness

2. Secure Digital Card (SD/SDHC/SDXC)

You can use File SD cards on several portable devices, including digital cameras, handheld computers, video camcorders, mobile phones, and audio players. Available since 1999, you can now find SD memory cards in ranges of capacities between 16mb- 1GB, with more to come.

Most SD cards typically weigh 2 grams and measure an estimated 32 mm x 24 mm x 2.1 mm.

With a maximum of 2GB capacity, the standard 2GB was no longer enough, so the manufacturers decided to introduce a memory card with the latest specification and a larger capacity card. The new standard came into the limelight in 2006. Not only were they developed to increase card capacity to over 32GB, but also to improve the overall performance, especially in terms of faster write and read speed.

The standard was called “Secured Digital High Capacity,” which refers to the card’s increased capacity. Unfortunately, many older SD card readers could not read SDHC cards, until manufacturers updated Ghent firmware to support the SDHC standard. Meanwhile, SDHC memory cards can read both SDHC and SD memory cards.

You can reasonably find SDHC cards on the market, although the higher SDXC cards may dominate the market.

The major difference between Secure Digital card (SD), Secure Digital High Capacity card (SDHC), and Secure Digital Extended Capacity card (SDXC) is their maximum range of memory storage capacity.

SD cards can be extended up to 2GB
SDHC cards can be extended between 4GB+ and 32GB
SDXC cards can be extended between 32GB and 512GB+
