SSDs track their own health through S.M.A.R.T. data including terabytes written (TBW), reallocated sector counts, wear leveling, and critical warnings — but Windows only exposes a fraction of this information. Most consumer 1TB SSDs have a 600 TBW rating, and once P/E cycles are exhausted, the drive enters read-only mode. Tools like CrystalDiskInfo expose the full S.M.A.R.T. dataset. Beyond monitoring, practical steps like keeping the PC dust-free, adding a heatsink for hot-running drives, and using surge protection can extend SSD lifespan.
