Comparison of SSD firmware reliability of different brands after using thousands of drives for five years
SSDs: A gift and a curse — Artur Bergman, founder of a CDN exclusively powered by super fast SSDs, has made many compelling cases over the years to use them.
Context & Ripple Effects
Operator-published reliability data has become its own genre: Backblaze set the template with its fleet-wide hard drive failure reports, turning procurement folklore into published numbers. Artur Bergman now runs the same experiment for flash, comparing SSD firmware reliability across brands using thousands of drives that powered his all-SSD CDN for five years.
The timing matters because the industry was racing up the capacity curve — Intel and Micron's 3D NAND announcement promised tripled density months earlier, and Samsung followed with a 16TB drive — while consumer SSD and hard drive prices were converging. As flash displaces spinning disk, firmware quality, not NAND specs, becomes what separates brands in write-heavy production fleets.
First-order effects
- Fleet buyers get a brand-by-brand firmware reliability ranking grounded in five years of production data, replacing marketing endurance ratings with observed failure behavior at CDN scale.
Second-order effects
- Vendors ranked poorly face procurement scrutiny from exactly the customers who buy by the thousands — the same dynamic that turned Backblaze's HDD reports into a reference point drive makers had to answer to.
Third-order effects
- If operator-published fleet data keeps setting purchase decisions, SSD competition shifts from capacity and speed spec sheets toward firmware maturity and telemetry transparency, with third-party endurance claims losing credibility.
The trend: Storage reliability is being adjudicated in public by hyperscale operators running their own fleets, pushing flash vendors to compete on fielded firmware performance rather than datasheet numbers.
