Abstract： In the domain of data storage applications such as radar, communication, and electronic countermeasure, in order to meet the requirements of writing large capacity SATA Solid State Disk Array (SSD) continuously, steadily and high-speedily, a RAID0 storage array system based on FPGA is designed. This system takes FPGA as the data processing core, which realizes functions such as data receiving, data buffering, data transmission, and data storage. According to the garbage collection characteristic of SATA SSD, logic function modules are designed and optimized. The repeatable tests show that sixteen SATA SSD has the storage capacity up to 32 TB, writing bandwidth up to 5.5 GB/s, and the ability to work steadily for a long time in the industrial environment.
