Specialist in Enterprise Storage Reliability & 18TB+ Testing Protocols.

I specialize in the critical evaluation of high-capacity enterprise storage, moving beyond the surface-level metrics provided in manufacturer Data Sheets. At Robert Electronics, we’ve developed a proprietary 100-Point Testing Protocol specifically designed for 18TB+ drives, HAMR/MAMR technologies, and high-density 24-bay chassis environments. My focus is on the mechanical nuances that dictate long-term reliability—such as how RV (Rotational Vibration) sensors impact actuator fatigue and why "OEM Pulls" require rigorous validation. Based in the industry with a strong focus on the European market (via ROBERTELECTRONICS.COM), I’m committed to transparency in the enterprise hardware secondary market. Currently maintaining an open-source technical repository on GitHub to help IT architects and data center managers make informed decisions based on real-world lab data rather than marketing specs.
