Symptoms
基准测试软件报告群联 P0221 SSD 的写入性能较差。Crystaldiskmark 和其他基准测试工具在非易失性高速内存 (NVMe) 驱动器上返回“磁盘读取/写入速度 0”。
Cause
驱动器固件 (FW) 无法在后台执行垃圾数据收集 (GC)。未清除单级单元 (SLC) 高速缓存。完整高速缓存使固件在前台触发 GC,从而限制主机命令。这会导致性能随时间推移而下降。
Resolution
提醒:开始更新之前,请执行以下作:
-
备份所有个人数据。有关详细信息,请参阅:备份和恢复
-
如果笔记本电脑上运行更新,请连接交流适配器。
将计算机上的固件更新到版本 2102.0105、A04 可解决此问题。下载并安装 Phison-P0221-Solid-State-Drive-Firmware-Update_PHYNH_WIN64_2102.0105_A04.exe 文件,请参阅:如何下载和安装戴尔驱动程序和固件
