Method
Failure rates are recomputed from Backblaze's Drive Stats (drive-days and failures) - source: Backblaze thru Q1 2026 - not vendor MTBF numbers; models Backblaze does not track use the manufacturer's series spec. Prices are the cheapest in-stock new Amazon offer per drive in DE, refreshed daily, with $/TB in USD for cross-currency ranking. Explore it all in the full filterable table.
