How long do USB flash drives really last? It’s annoyingly complicated
The lifespan of USB flash drives is influenced by various factors including the quality of NAND flash memory and environmental conditions. High-quality drives can retain data for over 10 years, but cheaper models may degrade faster due to electron leakage. For long-term storage, experts recommend using archival tapes or optical discs instead of relying solely on USB drives.
- ▪USB flash drives can last over 10 years under ideal conditions.
- ▪Data degradation occurs due to electron leakage, especially in cheaper models.
- ▪Extreme temperatures and humidity can negatively impact the lifespan of data on USB drives.
