PSA: When it comes to old SSDs, it's use it or lose it

SSDs left unplugged for extended periods can lose data due to charge leakage in NAND cells, but the risk is often overstated. JEDEC retention specs apply to end-of-life drives, not new ones, and consumer SSDs are rated to retain data for up to a year (QLC) or much longer (TLC, MLC, SLC). Enterprise drives have shorter retention windows (3 months) than consumer drives (1 year). Factors like storage temperature and drive age affect retention. Modern QLC 3D NAND has improved significantly. The key takeaway: always back up data before storing an old SSD, use the 3-2-1 backup rule, and don't rely on any single drive for long-term cold storage.
