Enterprise-class features and functions
The Deskstar™ E7K1000 delivers value to the enterprise with up to 1TB of capacity, 7200 RPM
performance and innovative technologies like Rotational Vibration Safeguard (RVS).
Systems with multiple drives installed are at risk for rotational vibration disturbance, which results from simultaneous operation of neighboring drives.
To mitigate any adverse impact on system per-formance, Hitachi-patented RVS technology works to counteract this disturbance ensuring drive performance and data integrity.
With a SATA 3Gb/s interface which utilizes the same physical connector as Serial Attached SCSI (SAS) drives, the Deskstar 7K1000.B is ideal for use in mixed-drive enterprise environments.
The drive also has a targeted 1.2 million hours MTBF rating and provides the industry’s most comprehensive 5-year warranty.

來不及修改了...

7K1000.B / E7K1000 最大容量單碟超過333GB

碟片密度達到每平方吋 270 Gbits

另外E7K1000部分是保固五年

真煩...本來要去買WD6400AAKS了,現在又殺出這個7K1000.B :laugh:
現在我又想看這2款640GB的效能比較了

簡直就是7200 rpm 裡面的最暴力硬碟

7K1000.B的數據傳輸率最高可達173.5MB/s

以網友測出來速度為準

7K1000.B這顆沒標出seek time,不知道是不是跟P7K500一樣是屬於GP型硬碟(只標idle power,卻沒寫operating power?)

期待正式的測試數據...
跟迅猛龍不知差多少喔...

標題這顆就是"日立 e7k1000系列1tb 640g即將大量到貨{光華}"這篇裡面實際上賣的那顆?
也就是單碟375G的那型號 :confused: E7K1000則是單碟500G的企業版本??

怪物硬碟啊 :eek:

這顆硬碟亂數讀取時間居然

還有那個wd 2TB綠色板亂數讀取跟寫入時間也很強


這兩顆單碟500G產品,亂數讀取,寫入時間也太快了吧
居然巴掉萬轉的暴龍150G
