Are Solid State Drives Reliable?

3319_ssd-2

Solid state drives (SSDs) are replacing hard drives. The advantages are compelling. SSDs are faster, quieter, and use less power, since they do not rely on a spinning disk. Unfortunately, these advantages come with a drawback. They may lose data, particularly if left at high temperatures or stored without power. In some cases data may be lost in a week or less.

  • Avoid storing computers with SSDs in the heat and do not let them sit idle for long periods of time.
  • Use hard drives instead of SSDs for long term storage and be sure to backup your data.

The original presentation from Alvin Cox at Seagate is no longer available on the internet. My guess is that it was removed because someone at  Seagate, which sells SSDs, found the report inconvenient; however, the data remains available through a number of articles, including some of those listed below.

SSDs can lose data in as little as 7 days without power
