How Long Can SSD Store Data Unpowered? Year 1 Update
#SSD #Archive #Testing
Long term SSD data storage test. How long can an SSD store data while unpowered? I'm doing my own basic test to store and check data after 1 year and 2 years left unpowered.

Due to suggestions, I did end up doing a read test of the data. I unfortunately did not do a read test when disks were new, but I do have the 1 year test results here:
102458 Total MB
683 Total Files
150 MB Avg File Size
1 Year Check:
SSD 1 (Worn): 207 seconds total ~ 495 MB/sec avg read speed
SSD 2 (Fresh): 225 seconds total ~ 456 MB/sec avg read speed
While I don't have the original read speed results, I'd say there is really no degradation in performance so far with those rates.
