A 64GB SanDisk SATA SSD Has Survived a 16-Year Endurance Ordeal, with More Than 140,000 Write Cycles and a Whopping 9 Petabytes of Data Written

A 16-year-old 64GB SanDisk SATA SSD has survived more than 9 petabytes of writes and over 140,000 write cycles.

After roughly 61,000 hours of operation, the drive remains usable but has developed uncorrectable read errors at Sector 0.

The case highlights the exceptional endurance of older SLC- and MLC-based SSDs while showing that serious errors can emerge without a reliable failure warning.
