[XF] SSD與HDD雙劍合併-WD Black²評測


https://www.xfastest.com/images/xftitle.png 前言
SSD(固態硬碟)與HDD(物理硬碟)一直以來都有本身的優缺點所在,SSD效能雖然優異,但高容量價格一直不太漂亮;HDD雖然擁有大容量的優勢,但效能卻連SSD的車尾燈都看不到:在桌上型電腦的應用上許多使用者會選擇SSD+HDD的組合,但在許多筆記型電腦的應用上沒有辦法與桌上型電腦一樣選擇SSD+HDD的組合;目前市面上雖然有SSHD(混合式硬碟)的產品,不過NAND Flash部分僅8GB,在頻繁的使用下,若NAND Flash故障就與一般的硬碟效能相同;在11月26號WD推出WD Black² Dual Drive產品,這款結合了120G SSD與1TB HDD於2.5吋硬碟,厚度9.5mm,在筆記型電腦、準系統及許多僅能安裝一顆硬碟的系統獲得了解決方案,並能獲得SSD+HDD組合的效能,這款WD Black²原廠提供5年保固,官方建議售價為新台幣8,999元,價格老實說不太親民,至於效能表現如何就繼續看下去嚕^^

本次測試分為兩個階段,分別測試SSD與HDD部分
首先可以先看到一顆120G SSD做完分割後直接做測試
https://picx.xfastest.com/johnuahuang/WD_Black2/SSD/System.jpg

先用CrystalDiskInfo軟體來看看
https://picx.xfastest.com/johnuahuang/WD_Black2/SSD/CrystalDiskInfo.jpg

首先採用ATTO來做測試
最高效能表現寫入:147MB/s 讀取:452MB/s
https://picx.xfastest.com/johnuahuang/WD_Black2/SSD/ATTO.jpg

在CrystalDiskMark表現部分,讀取部分415MB/s 寫入部分143.4MB/s,在4K表現方面相當出色讀取:33.17MB/s、寫入:120.9MB/s(隨機)

最後採用PCMark 7的Secondary storage suite測試,獲得了5127分的表現
https://picx.xfastest.com/johnuahuang/WD_Black2/SSD/PCMARK7.jpg

看完以上SSD部分的表現,充分表現了一顆SSD該有的效能水準

接下來看HDD部分,當然現在要先安裝驅動程式
https://picx.xfastest.com/johnuahuang/WD_Black2/WD_Setup.jpg
https://picx.xfastest.com/johnuahuang/WD_Black2/WD_Setup_1.jpg

安裝完驅動程式後可以看到另一顆1TB的容量

https://www.xfastest.com/images/xftitle.png 結語
WD Black²這款產品算是非常創新的一種產品,在效能表現上SSD部分讀取表現還不錯,但寫入方面應該還有努力的空間,HDD部分接近一般效能則無太大差異,這款產品與目前市面上SSHD(混合式硬碟)最大的不同在於SSD是獨立出來的磁碟分割,可以自由選擇將資料放置於SSD或是HDD上,在應用上多了許多空間。
這款WD Black²整體表現來說算不錯,讓想同時擁有SSD效能與HDD大容量於一顆硬碟使用者,帶來非常不錯的解決方案,但在厚度上如果有機會厚度降為7mm相信會吸引更多使用者購買,價格方面,這款建議售價為8,999元新台幣,門檻稍微偏高些,如果價格更為親民,相信WD Black²是個CP值不錯的產品!!

以上資訊提供給有興趣的使用者參考
