Toshiba's Under-the-Radar Achievement in PCIe 5.0 Speeds
Unveiling the Experiment: A Testament to Hard Drive Prowess
In 2023, Toshiba quietly revolutionized data storage capabilities by using 78 hard drives to reach the PCIe 5.0 speeds in an extraordinary JBOD (Just a Bunch of Disks) setup. Designed to highlight the scalability of hard drives, Toshiba's configuration delivered an impressive 17GB/s throughput with an astounding 1.5PB of raw storage. This pioneering moment has vital implications for data centers seeking to expand their storage solutions economically.
The Underestimated Capabilities of Hard Drives
Despite SSDs dominating the high-performance storage conversation, Toshiba's experiment underscores that hard drives still offer a compelling proposition for scaling capacities in data centers. Unlike their flash-based counterparts, hard drives remain cheaper per byte—a crucial factor when scaling up storage capacity to petabyte levels.
"The future of data storage is not just about speed; it's about capacity, cost-efficiency, and reliability. Toshiba's innovative JBOD setup is a leap in that direction." - Industry Expert
Key Metrics from the JBOD Experiment
- Achieved PCIe 5.0 speeds with 78 HDDs.
- 17GB/s throughput was recorded.
- 1.5PB raw storage capacity was delivered.
- The setup was cost-effective compared to an equivalent SSD array.

The Importance of Parallel Scaling
Parallel scaling is a critical feature in modern data management that allows for increased capacity without the prohibitive cost increases associated with other technologies. Toshiba's project is a blueprint for how industries can leverage parallel hard drive scaling to meet their growing data needs without breaking the bank.
