I’m in the process of thinking about off-site backups that only require minimal user input to prevent data rot.
SSDs are supposed to be bad for archival use because the data is stored as electrical charges in floating gate transistors which can dissipate away with time.
What if you were to:
- Take an SSD
- Install it in an external USB enclosure
- Connect the enclosure to a USB power brick.
- Connect the power brick to one of those WiFi-enabled “smart” power plugs (ex. Roku Smart Plug) and program the smart plug to just turn on once every week for 20 minutes.
- Assuming that the mains wall outlet continues to provide power to the smart plug, would this periodic scheduled “on” state be good enough to “re-energize” the floating gate transistors storing the data, thus prolonging the data integrity on the drive?
I’m assuming that all SSDs have automatic background processes that do this sort of housekeeping work every time they’re powered on?
