- Year 0 – I filled 10 32-GB Kingston flash drives with random data.
- Year 1 – Tested drive 1, zero bit rot. Re-wrote drive 1 with the same data.
- Year 2 – Tested drive 2, zero bit rot. Re-tested drive 1, zero bit rot. Re-wrote drives 1-2 with the same data.
- Year 3 – Tested drive 3, zero bit rot. Re-tested drives 1-2, zero bit rot. Re-wrote drives 1-3 with the same data.
- Year 4 – Tested drive 4, zero bit rot. Re-tested drives 1-3, zero bit rot. Re-wrote drives 1-4 with the same data.
- Year 5 - Re-tested drives 1-3, zero bit rot. Re-wrote drives 1-3 with the same data.
Will report back in 1 more year when I test drive 5.
