[簡測]Hitachi 7K3000 2TB & 7K1000系列 (圖多)
[前言]看這波硬碟這麼便宜，就升級一下手邊的硬碟吧！
7K3000 是已經看了好一下，找到四千以下的就入手了。
7K1000.C 也是在這次入手，這次買1TB還比去年買640GB便宜，真不知道以後TB級的會再掉多少...

4.Hitachi 7K1000 750GB 以前測得比較少，所以這邊數據沒有寫入和隨機讀寫的

https://i44.photobucket.com/albums/f1/lancechou/Hard%20Drive/HDTuneBenchmark7K1000-750GB.png
機本讀寫測試裡，滿明顯的7K3000跟5/i不太合，連頻寬都上不去，接上ICH9R後整個傳輸優勢就出來了！
而搜尋時間比較高是7K3000的罩門。
7K1000系列，單碟密度不斷增加，傳輸速度當然一直進步。
倒是4k讀取一代一代略為下降，倒是4k寫入一代比一代進步，不知道Hitachi在韌體上是怎麼設定的？

跑PCMark主要是稍微測試一般使用的狀況，準確性雖然可能不是太好，不過還是稍微看一下。
PCMark05:
7K3000雖然在5/i上頻寬比較上不去，但是靠著5/i的cache，倒是在這次四顆硬碟裡面跑出最高分！
至於7K1000系列，是4k寫入最快的.c，拿到了最高分。
PCMarkVantage:
7K3000則是輸給了7K1000.C。
7K1000系列也依然是7K1000.C最快！
[結語]
就這次簡單測試的結果。
7K1000.C比較適合當作系統碟。
7K3000雖然傳輸較快，但是搜尋比較慢，再加上每GB較7K1000.C高，單純地當資料碟會比較好。
也看的出來每一代的7K1000都有進步，到了7K1000.C平均傳輸已經破110MB/s！
最新的7K3000更不用說，平均傳輸更高達120MB/s，最高讀寫到了160MB/s附近，相當的厲害！
而噪音方面，個人就這四顆硬碟跑隨機存取的聲音來說，
7K1000 750GB非常大聲，很明顯的讀寫聲。
7K1000.B 640GB有比較安靜，但是在平常的環境下，會知道他有在讀寫。
7K1000.C & 7K3000 則是非常非常的安靜，要開機殼靠近聽才知道有在讀寫，
不過有伴隨的細微高頻聲，對高頻聲非常敏感的人可能要注意機殼隔音能力！
以上心得給大家做參考。 測試真多資訊@@
幫頂一個~"~+ Z大根本沒頂!!!
軟掉了嗎 (翻桌)
測得真是詳細阿.....
不過 HITACHI 的硬碟我都拿來當牧場 = = Hitachi 是俗又大碗.. 日立1T算起來比較超值
安靜又不貴的價位, 看來現時1T要道啦~~ 讀取退步，寫入進步，不知道是不是技術到了瓶頸~ Dell 6i 也是一樣的問題7k3000 上不去...
很期待有 H700 的測試篇 ~ 本帖最後由 vxr 於 2011-1-27 09:51 編輯
LSI 3Gb/s RAID Controller問題...
這不是不合的問題...
我很早就問過LSI了..
他給我很簡單的答覆...
>>Q: 6Gb/s HDD/SSD為什麼安裝在3Gb/s MegaRAID SAS Controller, 發現Negoiation Link Speed會強制在1.5Gb/s的速率呢?
>>A: LSI=> 3Gb/s MegaRAID controllers were designed before the 6Gb/s standard was developed. The card may not automatically set the correct link rate for 6Gb/s products. We cannot guarantee that the 3Gb/s speed will automatically be negotiated to with 6Gb/s drives connected to the 3Gb/s controller.
不要想太多...
LSI是不會在3Gb/s產品做升級的..
另外一個issue就是...
LSI 3Gb/s RAID產品不支持3TB以上單顆硬碟...
這不是做不到..
只是想不想做而已..
到目前為止LSI是沒有任何計畫對這些產品做任何保證..
樓主顯然要去檢查你在LSI控制器上連接6Gb/s HDD的Link Speed...
IR/IT產品使用SASFlash..
IMR產品則使用MegaCLI...
或著您也可以使用MSM去檢查.. Dell 6i 也是一樣的問題7k3000 上不去...
很期待有 H700 的測試篇 ~

DELL H700支持最新的MegaRAID版本...
顯然這是毫無問題的..
