Phison’s PS5026-E26 Max14um Gen5 SSD has achieved sequential read speeds of over 14,000MB/s, making it the fastest SSD currently available. The test results, with sequential read speeds of 14,175MB/s and sequential write speeds of 12,471MB/s, were demonstrated at the Flash Memory Summit 2023 and confirmed by TweakTown.
In their own testing, TweakTown achieved even higher speeds, recording sequential read speeds of 14,647MB/s and sequential write speeds of 12,741MB/s. These results were obtained using a system built with a GIGABYTE X670E AORUS Master motherboard, an AMD Ryzen 9 7950X CPU, 32GB RAM, and an MSI SUPRIM X RTX 3080 12GB GPU.
Phison was the first company to supply SSDs based on the PS5026-E26 controller with a PCIe 5.0 x4 interface, but earlier SSDs using this controller were not able to fully harness its potential due to limitations in NAND technology and other factors. However, with the use of Micron’s fastest 3D NAND devices and an innovative cooling system provided by Frore Systems called AirJet solid-state cooling, the Max14um SSD was able to achieve speeds exceeding 14,000MB/s.
The integration of the cooling system allowed the SSD to maintain relatively low temperatures even under demanding conditions. For instance, it only reached a maximum temperature of 54°C when subjected to full sustained sequential load tests under the worst possible conditions, with no external air flow beyond the cooling system itself.
This achievement showcases the rapid advancements in SSD technology, with increased speeds and improved thermal management contributing to enhanced overall performance and user experiences.
