Leaving unpowered SSDs in a warm room can kill your data fast

Many of us are in the business of collecting data from crime scenes. Some actually collect hard drives. This article from PCWorld highlights a new risk associated with unpowered SSD drives.

"A new research presentation shows that solid state drives can lose data over time if they aren’t powered on, especially in warmer environments. A powered-off drive in 104 degrees Fahrenheit may start seeing data loss after a couple of weeks.

The information comes from Seagate’s Alvin Cox, who as part of a presentation to the Joint Electron Device Engineering Council (JEDEC). Though the presentation is a couple months old, it was recently picked up by ZDNet, Slashdot and other sites.

Cox’s presentation shows basic performance requirements for both consumer and enterprise SSDs. It notes that consumer SSDs, when powered-off in 86 degrees Fahrenheit (30 degrees Celcius), should retain data for about a year. Bumping up the temperature by 9 degrees Fahrenheit (5 degrees Celcius) reduces the time of data retention by half. Store your SSD in 131 degree heat, and it might start losing data after a couple of days ..."
