Keep it Cool
The Joint Electron Device Engineering Council (JEDEC) recently tested solid-state drives (SSDs) made by Intel, discovering that when the power is off, SSD performance, battery life, and reliability severely suffer at a specific temperature.
According to the research findings, SSDs for consumers are capable of storing data for 2 years at 25 degrees Celsius, 1 year at 30 degrees, and 6 months at 35 degrees when there is no power supplied. It doesn't mean that data is lost right away after the power supply is lost, but that product reliability is drastically lowered afterwards.
As for corporation-oriented SSDs, data is stored for shorter periods of time. Whenever temperature rises by 5 degrees starting from 25 degrees, the length of the retention period for data was found to be cut in half. When corporate-oriented SSDs are stored at 30 degrees without power, data can be stored only for 10 weeks, and only 5 weeks at 35 degrees, according to JEDEC.
In the summer, more attention should be paid to take care of SSDs. When SSDs for consumers are kept at 55 degrees, data loss occurs 2 weeks after the power supply is discontinued. Data may totally disappear within a short period of time if SSDs are exposed to the direct rays of the sun, or kept in a car or indoors without air conditioning.
A source in the semiconductor industry said, “When data centers or corporations in which a lot of SSDs are concentrated do not adequately manage SSDs, it can lead to large accidents.” The source added, “There is a case where SSD data was lost completely after being stored for more than a year without being used.”
