This summer, I had the opportunity to work with Toshiba’s HDD Performance R&D team, trading lecture halls for labs and discovering what it takes to turn curiosity into real improvements. My project focused on seek-time prediction, in simple terms, estimating how quickly a hard drive can jump to the data you need. By first developing the feature in a simulator and then checking the most promising results on a test bench, I helped the team identify where meaningful performance gains could be expected before investing significant time.
Along the way, I worked closely with real hardware, sent read and write commands over SATA (the drive connection), pulled logs through UART (the serial port) to better understand drive behavior, and practiced writing clean, well-documented code. These experiences gave me a strong foundation in both hands-on hardware work and writing reliable software to support it. In the process, I even uncovered potential bugs in the firmware, which added to the learning experience and showed me the importance of careful testing and validation in real-world systems.
The most rewarding part was seeing analysis turn into action. I tested with common workloads, compared baseline and improved versions, and verified key results on real hardware to ensure the simulator lined up. I also created clear slide decks and flowcharts, delivering several short presentations that made the findings easy to follow. These presentations gave the team the insight to quickly decide whether to continue tuning or move on. It was a crash course in turning complex technical work into simple, actionable outcomes.
None of this happened alone. My manager, Johanna, kept the goal sharp and focused. Rick challenged me to back every claim with clean, repeatable evidence, and Indukumar guided me through smarter test design and clear communication. Thanks to their mentorship, I’m leaving with stronger problem-solving skills, a deeper appreciation for teamwork, and excitement to keep building in storage and firmware.
If you’re curious, hands-on, and love learning fast, Toshiba’s R&D team is a fantastic place to grow.
