Why Do You Need an SD Card Backup Device

The first reason you may want to use an SD card backup device is for the security of your data in the event of data loss. Keeping backups assures you that you'll still access your documents, music, videos, pictures, etc., when your SD card becomes corrupted or damaged. You may also delete files stored on your SD card by accident.

A backup device, therefore, becomes handy in such situations since you won't have to worry much about lost data. An SD card backup device is also important since it helps free up space on your SD card if it's almost full. Moving data to a backup device creates space to store additional files on your SD card.

The Different Types of SD Card Backup Devices Available

Different types of SD cards exist based on size, compatibility, and speed. They include the following.

1. Secure Digital (SD) Card

This is the oldest type of memory card type. It's large compared to the latest generations and measures 32mm by 24mm by 2.1 mm. The card provides maximum storage of 4GB and a transfer speed of 10mbps.

2. Secure Digital High Capacity (SDHC) Card

This is a refined form of the SD card that supports high-resolution video recording and image editing. It has similar physical attributes to the SD card but with a faster transfer speed. It also provides more storage space (32Gb) than a basic SD card. 

3. Secure Digital Extended Capacity (SDXC) Card

Compared to an SDHC, SDXC provides a larger storage capacity, making it more efficient. It's primarily beneficial for photographers or gamers. Most of these devices come with a storage range of 64GB to 2TB.

4. Micro SD Card

As the name suggests, a Micro SD is a lighter version of the SD card with almost similar features. Their main selling point is their size (small) and portability. It can store up to 16GB of data with a transfer speed of 8mbps.  

5. Micro SDHC Card

This memory card is a modified version of Micro SD. It sought to address the insufficient space offered by the latter. It can hold up to 32GB of data which is suitable for primary smartphone users. It also allows a data transfer speed of 10mbps.

6. Micro SDXC Card

This is the latest version of the Micro SDs and comes with advanced features. It provides a large storage space ranging from 32GB to 2TB. You won't need to delete some files or empty your SD card to create space for extra files.

7. Compact Flash Card  

A compact flash card is physically larger than any other SD card and has a high storage capacity. They have an ultra-high transfer speed for files and data.

How to Choose the Right SD Card Backup Device for You

The first thing to consider when looking out for an SD card backup device is its performance speed. Data transfer speed is essential since it helps to save time spent copying a given file to an SD card. Compact flash cards have the fastest transfer speed, while SD cards have the slowest.

Second, when considering the right SD card, you should check its storage capacity. A good SD card should allow you to store your files without running out of space. Another factor to consider is the card size. Micro SDs have the smallest size, while SD cards have an average size. Compact flash cards are the largest.
