  1. 2022年4月25日 · ATP提供固件和硬件解决方案,旨在保护SSD上的宝贵数据。. ATP HW+FW PLP提供先进的电保护,即使在断电的情况下也能确保数据的完整性,并在关键任务的应用中保存数据。. PLP机制的特点是独立的设计、固态电容和长寿命。. 对于采用ATP基于MCU的PLP的固态硬盘来说 ...

  2. 在正常系统关闭期间,主机首先向SSD警告系统正在关闭。. 然后,SSD准备断电,将数据从易失性存储刷新到非易失性闪存,然后向主机发送信号,表明驱动器已准备好断电。. 该过程完成了两项重要的工作:首先,确保在断电之前安全地存储了数据; 其次,映射 ...

  3. 2020年8月5日 · 磨损均衡机制允许闪存设备在所有块之间平均分配P / E周期。. 它可以防止过度使用的块过早磨损,因此可以最大程度地使用所有块。. 磨损均衡可延长使用寿命,并提高存储设备的可靠性和耐用性。. 图1. 带和不带磨损均衡的存储设备的图形表示. 磨损均衡有三种 ...

  4. MCU通过 I 2 C 接口智能地监测毛刺 电情况,并检查电容器的健康状态。 如果发生意外的断电情况,则聚合物钽电容器可为数据高速缓存刷新提供足够的维持电源。 MCU可以持续检测电源故障情况; 例如,对于2.5英寸固态硬盘,如果输入电压连续几个毫秒 ...

    • Introduction to Over-Provisioning
    • How Over-Provisioning Impacts SSD’s Performance
    • Conclusion

    In the past few decades, flash-based SSDs have sparked a revolution in storage devices. Unlike traditional electro-mechanical hard disk drives (HDDs) that use magnetic disks for storage, SSDs are made from an array of solid-state electronic storage chips, consisting of control units and storage cells (i.e., NAND flash chips, DRAM chips), thereby of...

    The garbage collection can severely impact SSD performance when it is near saturation with writes. To cope with this problem, over-provisioning provides additional space for the garbage collection process without heavily impacting the performance. The following two graphsshow the variation in peak performance and overall performance of a 256 GB SAT...

    Over-provisioning contributes to improving the endurance and write performance of the SSD, but it will reduce the user capacity; therefore, it is important to allocate an optimum amount of OP depending on the application. For write-intensive workloads, it is beneficial to compromise a certain portion of capacity for a significantly improved enduran...

  5. 2020年11月11日 · SSD endurance. 单层存储单元(SLC)NAND一直是要求最高可靠性、性能和耐用性的工业应用的“黄金标准”。. 顾名思义,SLC是一种NAND闪存,每个单元仅存储一位数据,因此它具有更快的写入速度和更长的使用寿命的优势。. 由于SLC在每个单元中存储的数据较少,与 ...

  6. 2023年9月4日 · In DDR5 server platforms, however, RDIMMs and UDIMMs are no longer pin-compatible. They are keyed differently, so you cannot insert UDIMMs on server motherboards that support RDIMMs. Intel ® Xeon ®, the lineup of Intel ® Core™ Processors, and the AMD EPYC™ Processor Family will support DDR5 ECC RDIMMs.
