3 Surprising Ways To Use Your Old SD Cards
By QUINA BATERNA
Despite their usefulness as storage devices, SD cards have become less necessary for the ordinary person as alternative options like cloud storage are becoming widely available.
As a result, you may find yourself with several unused SD cards lying around your home. Luckily, there are a few unexpected ways that you can still use them.
EFS
If you need extra security for your sensitive information, you can use your old SD cards, as they can store, transfer, and share encrypted file systems.
Microsoft describes EFS as an "additional level of security for files and directories." You can take additional steps to protect your files, like adding a PIN to your SD cards.
Bootable Storage
SD cards can also be made bootable, like an external hard drive. They have key advantages over external hard drives, such as a wider operating temperature range.
According to EaseUS Software, most external hard drives have a recommended operating
temperature of 41°F to 95°F. However, some SD card models can function from -40°F to 185°F.
Embedded Systems
Unlike operating systems, embedded systems are designed to perform only one type of task. SD cards are a perfect way to run embedded systems for various devices.
Some embedded systems you may encounter include EV charging stations and wearable devices. However, you can also use them for an almost endless range of Raspberry Pi projects.
