Loli69 Posted September 19, 2024 Posted September 19, 2024 各位大佬好，我的Unraid主要用來儲存動漫和相片，是由零刻的N100 mini PC 和5盤位的DAS組成，並使用USB 3.2 gen 1至Type C進行連接。最近用來傳輸檔案發現速度異常緩慢，而且無法長期維持2.5G應有的傳輸表現，幾秒內從260多mb/s，立即下降至40多mb/s。 我檢查了線材和DAS，運作都正常。唯一最大的改變就是幾周前從6.12.10升級至6.12.13版本，因為看見了更新詳細有針對硬碟進行優化，所以升級了。 五個硬盤分別是WD紅盤2T、希捷狼盤4T x2、東芝MG08 8T、東芝MG09 18T，另外再透過DAS菊花蓮USB連接了一個2.5寸三星SSD 500GB。 共享檔案都是一個硬碟各一個，沒有集成。每次傳輸都是針對一個硬盤輸入，之前能夠長期維持在140~160mb/s，而且現在的硬盤閒置空間很充足。 希望各位大佬能夠幫我看看問題出在哪裏，我個人判斷是DAS和NAS之間的控制器可能出現了兼容性問題，謝謝各位！ sl8620-diagnostics-20240919-2253.zip Quote

Loli69 Posted September 20, 2024 Author Posted September 20, 2024 我這裏有看到USB 3.2，但是DAS走的全部都是Bus 001(USB 2.0)，那麼問題是線材嗎？之前好像也不會這樣 Quote
Loli69 Posted September 20, 2024 Author Posted September 20, 2024 剛才把連接菊花蓮的SSD移動至零刻N100 mini PC內的sata 插口，整個橋樑的連接好像回到正常了。傳輸速度也回復正常，謝謝大佬的指點！真的十分感謝🫡 Quote
