Symptoms

基準測試軟體報告 Phison P0221 SSD 上的寫入性能不佳。Crystaldiskmark 和其他效能指標工具會在 Non-Volatile Memory Express (NVMe) 磁碟機上傳回「磁碟讀取/寫入速度 0」。

Cause

磁碟機韌體 (FW) 無法在背景中執行垃圾收集 (GC)。未清除單層單元 (SLC) 快取。完整的快取記憶體會使韌體在前景觸發 GC,這會限制主機命令。這會導致效能隨時間推移而下降。

Resolution

注意:開始更新之前,請先執行下列步驟:
  1. 備份所有個人資料。如需詳細資訊,請參閱:備份與復原

  2. 如果在筆記本電腦上執行更新,請連接交流電變壓器。

將電腦上的韌體更新至版本 2102.0105、A04 可解決問題。若要下載並安裝 Phison-P0221-Solid-State-Drive-Firmware-Update_PHYNH_WIN64_2102.0105_A04.exe 檔,請參閱:如何下載和安裝 Dell 驅動程式和韌體
