Recomputed from Backblaze's raw Q2 2026 Drive Stats (the tidy report isn't out yet): AFR now spans full-year 2025 + Q1 + Q2 2026, ~1.41% fleet (was ~1.34% through Q1). Dated snapshot 2026-09-04. Catalog: 273 drives (167 HDD + 106 SSD), 25 with a Backblaze failure rate. - Added recent SSDs: Crucial P510 + Corsair MP700 Elite (budget PCIe 5.0), Synology SNV3410/SNV3510 (NAS-cache NVMe, SNV3510 has PLP). - Sub-TB drive capacities are now reported correctly (400/500/800GB were 0 TB). - NAS enclosures dropped from the export (not drives).
