As to the topic of SD card lifespan, many people come up with the question: how long do SD cards last. So, we start a discussion on this topic in this post, and please join the discussion if you have interest in this topic.

SD cards can be found on various digital devices including computers, phones, MP3 players, cameras, and so on, and they are the key parts of some aforementioned devices — all data is saved on the tiny storage device. Therefore, lots of people concern about SD card lifespan and have the question: how long do SD cards last? Now follow MiniTool Partition Wizard to figure it out.

How Long Do SD Cards Last?

SD cards are designed to last for 10 years or more, but time has less to do with the lifespan of SD cards than the number of write-and-erase cycles. In other words, it is better to predict the SD card lifespan from the perspective of the frequency of use of the SD card. Well, how many the write-and-erase cycles of SD cards are? Keep reading.

SD cards take advantage of NAND Flash (a type of non-volatile storage technology) to store data on a series of electronic components called NAND flash chips, and there are three main types of NAND Flash:

  • Single-Level Cell (SLC)
  • Multi-Level Cell (MLC)
  • Triple-Level Cell (TLC)

The different type of NAND Flash has different Program Erase P/E cycles (the processes of erasing and then writing a cell), and their typical P/E cycles are as follows:

  • SLC: 90,000 and 100,000
  • MLC: 1,500 to 3,000
  • 3D TLC: 500 to 3,000

So, check if there is information on your SD card saying that the SD card uses SLC, MLC, or TLC, and then recall how frequently you use the SD card. Based on the information, you will get a rough answer to the question “how long do SD cards last”. There is another question of SD card lifespan “how to extend the lifespan of SD cards”.

How to Extend SD Card Lifespan?

Here are some tips for extending the lifespan of SD cards, from how to purchase a reliable SD card to how to check SD card health.

Choose (Multiple) SD Cards from a Reliable Brand

The reliable brands are the SD Association-approved brands like SanDisk, Lexar, and Transcend. The SD Association, founded in 2000, is a global ecosystem of companies setting industry-leading memory card standards that simplify the use and extend the life of consumer electronics, and neither manufacture nor market any product.

If you use an SD card as the main storage device, you are suggested to purchase multiple SD cards. There are two reasons: having multiple SD cards will minimize the writing and erasure frequency on memory cells; storing your files on multiple SD cards makes it impossible to lose all your files.

Never Force an SD Card into a Device

When you insert the tiny storage device into a computer or something else, please do not use too much force. If you have to use too much force to insert your SD card, the reason could be incompatible orientation or size.

Don’t Directly Edit Files on the SD Card

Editing files on the SD card is a process of continuously deleting and writing data. Moreover, this might damage the files. The correct and safe operation is to copy and paste the files (not cut and paste) on the SD card to the computer and then edit them.

Safely Remove the SD Card from the Device

When you finish the work like transferring files from your SD card to your computer, please properly eject and remove the SD card from your computer as follows:

  1. Press Windows + E to open File Explorer.
  2. Locate the SD card on the pop-up window and right-click it to choose the Eject
  3. When you see the SD card’s icon turns gray, you can remove the SD card.

Don’t Leave the SD Card in the Computer

When you don’t need the SD card, please do not keep it connected to the computer. Left in the computer, it will continuously access the directory to see if there are any changes. That is identical to a write cycle, so the write cycle is wasted and the lifespan of the SD card is reduced.

Keep the SD card Clean

After removing the SD card from a device, you’d better store your SD card in a case to keep it from dust. While when you use it, please avoid using it in a dirty or dusty situation. In such a situation, there is numerous debris, and they will build up on the contact points and thus cause SD card malfunctions. Also, do not use the SD card in moisture or extreme temperatures, because the two factors will lead to SD card malfunction.

Back up Your SD Card to Another Storage Device

For data security, it is highly recommended that you back up your SD card to another storage device like an external hard drive. Even if the SD card is lost or damaged, you do not need to worry about data loss.

Don’t Share the SD Card with Other Devices and Others

Different devices require different speeds of data writing and different forms of processing. Therefore, the SD card might be incompatible with different devices. Moreover, SD cards can malfunction or even be infected with viruses if they are constantly switched between devices. If you have to share it between devices, please transfer its data to a different storage device and format it between each use.
