When it comes to data backup, there’s no such thing as a failproof storage device. Even high-quality SSDs can fail over time. XDA warns that unpowered SSDs sitting in drawers are at risk of failure due to power issues.
Unlike hard drives, SSDs don’t store data forever when powered off. Their lifespan depends on various factors, including technology and storage conditions. Some high-end SSDs may last up to 10 years without issue, but cheaper models might only retain data for a year or two.
Experts say that SSDs have limitations that make them unreliable for long-term data backup. They can be programmed and erased only so many times, and excessive data writes increase the risk of failure. The key takeaway is that all storage devices will eventually fail if not used regularly.
To ensure your files are safe, follow a solid long-term storage workflow, such as the 3-2-1 rule: have three copies on two different media, one copy offsite. Regularly check and maintain your drives to avoid relying on unpowered SSDs for data backup.
