What happened
A peer-reviewed study analyzing 443,000 Backblaze hard drives across 1.66 million drive-years found HGST most reliable and Toshiba least reliable, with Seagate close behind Toshiba on the unreliable list. Seagate and Toshiba HDDs failed at roughly twice the rate of WD and HGST drives.
Why it matters
If you are speccing on-prem storage or NAS hardware for a Malaysian startup or homelab, this peer-reviewed dataset gives you a concrete basis to prefer HGST or WD over Seagate and Toshiba — the failure rate gap is approximately 2x, not marginal. For teams fully on cloud (AWS/GCP/Azure), this is informational only since you don't select the underlying drives.
Discussion angle
Whether this Backblaze dataset translates to Malaysian climate conditions (heat, humidity) where failure rates may differ, and whether on-prem HDD selection still matters versus just using cloud object storage.
