6 Ways to Make the Most of Your Full-Size SD Card in 2025

Many people thought they would get a lot of use out of their SD cards, but then they just sat in a drawer for years. In fact, the world hasn't completely abandoned this type of memory card, and there are still many good ways to 'revive' them.

If you're still shooting with a dedicated camera, you'll definitely need an SD card (unless you spend thousands of dollars on one of the rare models with built-in memory). Most cameras store on memory cards, not built-in memory.

While many phones today use microSD, cameras often require full-size SD cards. But rest assured, most microSD cards have adapters that can be inserted into larger SD slots.

Install on security camera

Home security cameras no longer require expensive service contracts or separate monitoring rooms. Many models store data directly on SD cards and review it via a phone app. The big advantage is that it does not have to be uploaded to the company's servers, avoiding the risk of data being exploited for advertising, AI, or shared with third parties.

For Raspberry Pi project

 

Tiny computers like the Raspberry Pi are great for DIY projects. They typically don't have any internal storage, so installing an operating system on an SD card is the quickest way to get your system up and running.
From turning your Raspberry Pi into a Nextcloud personal cloud server, a Plex media server, to a Home Assistant smart home platform… it's all possible. With a 512GB or 1TB SD card, you don't even need an external SSD.

Make a compact backup

Before cloud storage, backing up to external storage was a good habit. SDs aren't the fastest or most durable storage, but they're better than nothing.
The 3-2-1 rule still applies: 3 copies, in 2 different places, 1 off your main device. A small SD card that fits in your wallet, in case you need to leave the house quickly. Remember to encrypt or only store non-sensitive data.

Expand laptop memory

Some laptops have SD card slots — use the card to add more storage without having to replace the SSD or get a new machine. Simple, neat, cheap.

Create an 'offline library' for the whole family

Have a collection of DRM-free books, stories, or music? Instead of building an expensive server, just copy them to an SD card and share them directly with your loved ones. Not as convenient as an online server, but simple, fast, and almost free.

Bottom Line: SD cards are a tech item that geeks tend to accumulate over time. Don't let them collect dust — give them a second chance. And if you're planning on buying more, a card from a reputable brand is a cheap, durable investment.
