Kioxia has announced the upcoming release of two highly anticipated PCIe 5.0 SSDs, the EXCERIA PRO G2 and EXCERIA G3, scheduled to hit the market in January 2026. As flash memory prices experience significant fluctuations, these new models are expected to capture the attention of tech enthusiasts and professionals alike.
Performance and Specifications
The EXCERIA PRO G2 is positioned as a flagship SSD with impressive specifications, catering to users who demand top-tier performance. It offers storage capacities of 1TB, 2TB, and 4TB, constructed with advanced BiCS FLASH TLC flash memory technology.
- Read Speed: Up to 14.9GB/s
- Write Speed: Up to 13.7GB/s
- Random Read IOPS: 2.3 million
- Random Write IOPS: 1.95 million
This SSD not only excels in speed but also guarantees reliability, making it suitable for heavy workloads. The 1TB model has a write endurance of 600TBW, and the 4TB version boasts an impressive 2400TBW lifespan. Users can enjoy peace of mind, knowing that both models have a commendable failure-free interval of 1.5 million hours.
Design and Usability
With an M.2 2280 form factor (22.15 × 80.15 mm) and a thickness ranging from 2.38 mm to 2.63 mm, the EXCERIA PRO G2 is designed for optimal performance without sacrificing form. However, its power consumption, ranging from 8.4W to 9.6W, suggests that it may not be the most suitable choice for laptop users looking for efficiency.
While the theoretical performance cap for PCIe 5.0 x4 SSDs is 16GB/s, practical applications have seen speeds typically ranging between 12-14GB/s. Kioxia’s latest offering, with its 14.9GB/s performance, stands out as a leading option in the consumer SSD market.
Alternative Choice: EXCERIA G3
For users who do not require the extreme performance of the EXCERIA PRO G2, Kioxia presents the EXCERIA G3 series. The initial release will feature 1TB and 2TB capacities, with a 4TB model to follow later in 2026. Manufactured with BiCS QLC flash memory, the G3 promises excellent value for everyday computing needs.
- Read Speed: Up to 10GB/s
- Write Speed: Up to 9.6GB/s
- Random Read IOPS: 1.6 million
- Random Write IOPS: 1.45 million
Despite the performance downgrade, the EXCERIA G3 maintains a robust write endurance: 600TBW for the 1TB model and 1200TBW for the 2TB variant. This series also comes with a five-year warranty and a lower power consumption range of 5.5W to 6.4W, making it a more practical choice for various use cases.
Conclusion
Kioxia’s launch of the EXCERIA PRO G2 and EXCERIA G3 exemplifies their commitment to delivering high-performance SSDs catering to diverse user demands. Whether you are a professional needing cutting-edge speeds or a casual user seeking reliable storage solutions, Kioxia’s new offerings promise to meet and exceed expectations.
As the SSD market continues to evolve, these releases signal exciting advancements in technology, paving the way for future innovations.
