    以下簡介存儲設計平台、技術、特別功能,以及高性能固態硬盤(SSD) 控制晶片的應用實例:

    技術亮點

    高性能SSD控制器

    Data Packaging Efficiency (UASP)

    Memory_SSD Controller_USAP

    Key goals of UASP

    • Support multi-commands queue and return full SCSI status and sense data
    • Leveraging USB3.0 streaming capability to implement the multiple commands queuing
    • Asynchronous notification thanks to USB3.0 dual-simplex transaction
    • Improve 30% efficiency comparing to current Bulk Only Transaction (BOT) protocol for Mass Storage Class

     

    應用於企業數據中心和雲存儲的NVMe (Non-Volatile Memory Express) 控制器

    • Native PCIe interface NAND Flash Storage
    • Provide high efficient solid state storage platform for enterprise application
    • Enterprise Data Center and Cloud Storage
