Seagate ST16000NM000J 16 TB failure rate and reliability
– Not graded: too little data
Backblaze logged 269 drive-years on the Seagate ST16000NM000J from Q1 2023 to Q3 2026, with 171 in service at the end of that period. In that time 6 drives failed, an annualised failure rate of 2.23%.
That is too little running time to grade: we require 100,000 drive-days, and this model has 98,013. Treat the rate as a rough indication only.
Failures have risen: 2.55% over the latest 7 quarters against 1.38% before. Rising rates often mean a model is ageing.
