由於傳統BIOS的限制以及技術上的門檻,之前3TB的硬碟在市場上流通率真的比較低
Hitachi日立環球儲存推出效能級的Diskstar 7K3000 3TB內接式硬碟,
以標準的7200轉馬達搭配高儲存密度的磁碟片
目標針對高容量與高效能皆有強烈需求的使用者特別打造,
搭配合理的售價相信接下來應該非常好搶市

其實3.5"內接式硬碟的外觀都大同小異
型號與規格說明

容量3TB,傳輸介面為SATA 6Gb/s,馬達轉速7200 RPM

由碟片區的厚度看來應該是塞了滿滿的碟片,官方資料看來是總共5張碟片,單碟600GB
測試平台與環境
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/07.jpg
CPU: Intel Core i7-2600K @ 5.0 GHz
Cooler: Antec KÜHLER H2O 920
Thermal Compound: Antec Formula 7
MB: ASRock Fatal1ty P67 Professional
RAM: Kingston HyperX H2O DDR3 @ 2133MHz 9-10-9-27
Graphic: Galaxy GTX 560 Ti GC Edition
Storage: Kingston SSD Now V+100 128GB
PSU: CoolerMaster 1000W
Chassis: CoolerMaster Test Bench
Monitor: Dell U2410
上機之後第一個動作就是選擇硬碟分割樣式
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/08.png
要享受完整3TB的空間請一定要選擇GPT模式分割
如果選擇MBR分割因為硬體規格本身的限制就會出現下面這種狀況
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/09.png
開始分割磁區
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/10.png
只使用單一分割磁區
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/11.png
TB等級的10進位改2進位遞減算法是(1000/1024)^4大約等於0.909,格式化完成之後3TB的
硬碟只會有2.72TB可用空間
效能實測
HD Tune Pro 4.60標準讀寫
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/12.png
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/13.png
HD Tune Pro 4.60檔案效能
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/14.png
HD Tune Pro 4.60隨機存取
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/15.png
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/16.png
HD Tune Pro 4.60額外測試
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/17.png
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/18.png
CrystalDiskMark 3.0
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/19.png
ATTO Disk Benchmark
http://picx.xfastest.com/elvis/HDD/Hitachi/7K3000-3TB/20.png
小結
在單碟600GB與7200RPM的加持之下,線性讀寫的幾乎都可以達到150 MB/s
搭配SATA 6Gb/s的傳輸介面在突發讀取速率還可突破300 MB/s
隨機存取約為15ms,以這麼大容量的硬碟來說還在可以接受的範圍
雖然現階段售價大約是7K3000 2TB的兩倍,但卻是目前市場上售價最低的3TB硬碟
對於超大容量需求的玩家來說,
Hitachi日立 Diskstar 7K3000 3TB的性能表現非常值得在選購時參考!
