Memory cards are used for mobile phones and laptops, cameras to expand their memory capacity. These are typically called microSD cards. It’s an abbreviation of micro secure digital card.

Secure Digital, officially abbreviated as SD, is a proprietary non-volatile memory card format developed by the SD Association for use in portable devices. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic and Toshiba as an improvement over MultiMediaCards, and has become the industry standard.

There are different types of memory cards:

  • Micro SD card – slowest and oldest technology
  • SDHC high capacity
  • MicroSDXS for better photos and full HD video. The abbreviation SDXC means Secure Digital Xtended Capacity.

Just make sure that the card you purchase is compatible with your device. You’ll want to purchase your memory card from a reputable store and look for brands like SanDisk, Lexar, Delkin and Samsung.  For smartphones, I recommend the SanDisk Extreme or Extreme Pro microSD cards.

How to add a microSD Card to Your Mobile Phone

  • Carefully remove the panel with a pin included with your mobile phone. The logo on the front of the card faces up. Then gently push the panel back in.
  • For the safest results, turn the phone of your device off beforehand. You’ll need to restart the phone for it recognize it has been inserted.

If you have a number of different SD cards then you might like to purchase a case to hold them. I bought mine off eBay for under ten dollars. You’ll want to have a system to remember which memory cards are empty and which are full of data. You might like to use the system of ‘the right pockets are the ones to write to’, while the ones of the left are full.

SanDisk Extreme® microSD™ UHS-I Card with Adapter Review

To solve my file storage issues on my smartphone, I bought a SanDisk Extreme® microSD™ UHS-I Card with Adapter. It is ideal to use with Android smartphones and tablets, action cameras and drones. The cards have powerful read and write speeds for fast shooting and transfers. It has been built for and tested in harsh conditions, making it temperature proof, waterproof, shockproof and x-ray proof.

These memory cards are ideal for recording in outdoor environments, weekend trips and sporting events. Look for the A2 logo to see it has met the specification for loading apps faster. You might need an adapter if you want to transfer the data and files to your personal computer or laptop later on.

If you’re a Nintendo Switch fan, then look out for the dedicated SanDisk micoSDXC card. It lets you add up to [64/128GB] of space to your system.

 The SanDisk and other memory cards are available in different sizes from 32GB, 64GB, 128GB, 256GB, 400GB, 512GB and 1TB.
