很久沒有發文了,今天實驗成功,跟同好分享一下。
如果使用的機器是 ThinkPad X1 Yoga, 而且您機器的硬碟是 Samsung PM961(MZSLW...)
非常建議更換SSD Storage Controller 的驅動程式。先看結果:
這是使用三星自己的驅動測試結果,小括號"()"裡的數字是使用Windows驅動的結果:

要看看你的硬碟是哪...(恕刪)
我的 X1 Yoga 是 950 Pro 走 PCIE 的應該驅動都可以換對吧
目前用內建的

更新後,感覺沒啥差別@@

方塊、廣場、SQUARE
這個部份是正常的嗎?謝謝。

我已經去東芝的網站更新過韌體,但在寫入這塊還是分數很低@@
附上我還沒更新時的速度,不知道有人遇到類似的狀況嗎?

提供相關資訊給使用Toshiba的朋友:
1. http://tinyurl.com/jgrxosl
這個討論串的倒數第二篇文章有提到,更新TOSHIBA的韌體:http://tinyurl.com/z8uosed
請自行下載兩個韌體做更新。
2. 關閉Write-Cache Buffer Flushing:http://tinyurl.com/jqx9sky
根據這個討論串的說明,關閉Write-Cache Buffer Flushing可以恢復原本SSD的速度,可參考這個連結:http://tinyurl.com/qc8rwto
圖示裡面的兩個box都要勾選。之後再使用AS SSD Benchmark,分數就會正常許多了。
備註:不過跟據網路上找到的資料,關閉Buffer似乎有其風險存在,所以預設值是開啟的,請自行斟酌。
