There are some major types of memory cards that can be used on ordinary electronic devices such as a digital camera. These types of memory cards are different sizes, and as technology has evolved, over time, the cards have become smaller in physical size, but have increased in logical size.

Types of memory cards

  • PCMCI (International Association of Personal Computer Memory Card)
  • The PCMCI standard has been expanded several times and is compatible with a wide variety of devices. There are three types of PCMCI cards. All three have the same rectangular size (85.6 to 54 mm), but different widths:
  • Type 1¬†cards can be up to 3.3mm thick, primarily for adding extra ROM or RAM to a computer.
  • Type II cards can be up to 5.5mm thick. These cards are often used for fax modem and modem cards.
  • Type III cards can be up to 10.5mm thick, which is suitable for portable disk drives.

Why Do we have Different Memory Cards

Every camera manufacturer uses different sizes and shapes for its products. This includes lens mounts, flange distances, lens sizes, batteries, and cables, to name just a few.

Memory cards are no different. They are available in different sizes, both in terms of storage and fitness. Some manufacturers like Canon prefer Compact Flash (CF) memory cards, while others opt for the smaller Secure Digital type.

You should check the camera specifications before buying these memory cards. Some, such as B. Micro Secure Digital, can be used with an adapter, but you cannot reduce the size of SanDisk memory cards.

What Memory Cards Are Available

Here You will find that CompactFlash and Secure Digital, both micro and normal, are the most common types of memory cards.


CompactFlash (CF Card) is a memory card for professional photographers. Most high-end DSLRs, such as the Canon EOS-1DX Mark II, use CompactFlash cards.

These are physically larger than SD cards, and they are used sparingly. They often have large capabilities and can run at very high speeds. There are two types of CompactFlash cards to accommodate different capabilities

  • Type I cards are 42.8mm x 36.4mm x 3.3 mm thick
  • Type II cards are 42.8mm x 36.4mm x 5.5 mm thick.

Secure Digital Card (SD card)

SD card is used for small devices. The size is 32mm x 24mm and 2.1mm thick. They generally work well, but not as quickly as other SD cards. These are limited to 4 GB. SD memory cards have been used since 1999 and are now capable of between 16 megabytes and 1 gigabyte.

MiniSD Card

After the success of the SD card (Secure Digital Card), the miniSD memory card was developed to meet the requirements of the mobile communications market. The MiniSD card offers the same advantages as the SD card but is smaller than the original SD card. MiniSD cards are generally found in many newer cell phones with features such as built-in digital cameras, downloading and gaming, especially in cell phones where the miniSD meets the requirements for increased data storage. MiniSD cards measure 21.5 mm x 20 mm x 1.4 mm and usually offer 16 MB to 256 MB of storage space.


The MicroSD format is mainly used in mobile phones and other small portable devices and is currently available with a capacity of up to 4 GB. This corresponds to approximately 1/4 of the size of the SD card at 15 mm L 11 mm W 0.7 mm. The MicroSD card is the smallest memory card available.

Card adapters can be purchased for backward compatibility. This means that microSD cards can be used in the SD and MiniSD slots and microSD cards in the SD card slots.


The MultiMediaCard (MMC) was introduced by SanDisk and Siemens in 1997. The card itself measures 32mm x 24mm x 1.4mm and is often used in place of the SD card. The speeds of an MMC are around 2.5 MB / s and they can often be used in SD card readers.

Sony Memory Sticks

Sony memory sticks are lightweight, compact, and designed for a wide range of devices, including digital cameras, recorders, etc. With an adapter, most Sony memory sticks can be used with almost all Memory Stick PRO compatible products.

  • Memory Stick Micro (M2): 15 mm x 12.5 mm x 1.2 mm
  • Memory Stick PRO: 50 mm x 21.5 mm x 2.8 mm. The Memory Stick PRO format has an 8-bit parallel interface with theoretical transfer rates of up to 480 MB / s. It is widely used in digital cameras and high megapixel digital camcorders.
    Memory sticks PRO DUO: 31 mm x 20 mm x 1.6 mm. Memory Stick PRO Duo media make up about a third of the volume and half the weight of standard-size media, but offer all the advanced features of Memory Stick PRO media.


The SmartMedia cards introduced by Toshiba in 1995 are obsolete, despite their popular use for five years. SmartMedia cards are 45mm x 37mm x 0.76mm in size and can be found at peak times in versions with 16MB, 32MB, and 128MB.

XD-Picture Card

XD-Picture Card is a type of removable flash memory developed for use in digital cameras. The XD is an ultra-compact, 20mm x 25mm x 1.7mm size. The XD-Picture Card was developed by Fujifilm and Olympus, which is used in many models of Olympus and Fujifilm digital cameras.
