SD cards are great sources of extra storage for your computer. You could store gigabytes of information on SD cards. These are great for both computers and also for cameras. Also, for digital cameras and at its core, the SD card is really a flashdrive. It stores data and doesn’t get flush out when you reboot your device. If you’re paying attention to USB memory or flash memory or SD cards, you would noticed that the amount of storage for data cards have increased over the years. It used to be that, you have to pay an arm an a leg for a one gigabyte of storage. Now, you have huge SD cards with massive storage space for a small amount of money. Well, if you are happy about that piece of news. Here are some bad news. Your SD cards may not be as secured as you think.
You might have an SD card that you think is empty. Guess what, it may have copied the data that you deleted in a hidden section of the SD card. People might be able to access the firmware of your Sd card to access that hidden area. Wait, it gets even worse. Because of the way SD cards are made, there is a lot of junk space on the sd card. So, a manufacturer could say that you are buying a 4gb card when in reality the actual storage is actually 2 Gb and you’re really rolling the dice if you can accommodate 4 Gb. Technically speaking, you can store 4 Gb but considering the fact that the firmware on the card is trying to keep the memory intact, all that storage space may not be usable. You pay a steep price for the ever decreasing prices of SD cards, these cards decrease in price because there’s a lot of junk space that is technically expanded space. But you’re really rolling the dice if you’re gonna store data in that space. The big news here is that, the firmware on your SD card is often unsecured. This mean if you have malware or a virus on your computer or device, it can interface with the firmware and reprogram that. Scary situation.
