Phison Shows Off 2025 SSD RAID Array at Computex 32 with Record Read Speed of 113,6 GB/s
The exhibition Computex 2025 company Phison demonstrated an impressive storage system for AI workstations - a configuration based on 32 SSD with Phison E28 controller, which combined devices into a single array via an expansion card Apex Storage X16 Gen5. The demonstration used workstation based on AMD Ryzen Threadripper PRO 7985WX, ASUS WRX90E-SAGE SE motherboard and three Apex PCIe devices.
The test in CrystalDiskMark recorded sequential read speed of 113 MB/s (601 GB/s) и write speed of 104 MB/s (628 GB/s), making this array one of the fastest solutions demonstrated in the consumer and professional segments. A Phison representative specified that Windows Kernel was limiting performance, and in other OS you can expect even better results.
Phison PS5028-E28 is the latest PCIe 5.0 controller, built on TSMC's 6nm process technology and using a quad-core architecture. One SSD based on it provides up to 14,8 GB/s read and up to 14,0 GB/s write, and the maximum capacity can reach 32 TB per drive. The demonstration used 32 M.2 2280 drives, evenly distributed across three X16 cards.
Each card Apex Storage X16 Gen5 supports up to 16 M.2 drives with full bandwidthusing 84 lines via Microchip PM584 switch. The addressable capacity is also declared to be up to 128 TB per card, which, when using three boards, theoretically allows us to achieve 384 TB in a single array - depending on the SSD configuration.
Phison positions the E28 as solution for enthusiasts, creators and workstations, capable of providing instant access to data and supporting AI algorithms in real time. Given the growing demands for input/output speed when working with LLM and 3D rendering, such arrays may become the standard in the high-end segment by 2026.
