Summary
The article explains that solid-state drives (SSDs) are not suitable for long-term data storage when left unpowered. Unlike traditional hard drives, SSDs store data in flash memory cells that require periodic electrical refresh to maintain data integrity. When SSDs are left unpowered for extended periods (typically 1-2 years), the charge in these cells can leak, leading to data corruption and loss. The article discusses the technical reasons behind this phenomenon, including charge leakage in NAND flash memory cells, and provides practical advice for users who need to store data long-term, recommending traditional hard drives or cloud storage as better alternatives for archival purposes.
