7200rpm快得去邊...

點解唔快呢?你500GB/plate,又要做到10000RPM,難的喔!
7200 vs 10000PRM and高密度 vs 低密度,兩睇。

日立雖然在上月上旬發布了7200RPM轉速的2TB容量桌面硬盤和企業級硬盤,但五碟裝的設計總是讓人心存忌憚。今天,西部數據也發布了自己的這兩類產品,均為單碟500GB、四碟裝

桌面型號隸屬於高性能的Caviar Black黑盤系列,編號“WD2001FASS”,采用SATA 3Gbps接口,緩存容量64MB轉速恒定為7200RPM ,尺寸147.0×101.6×26.1毫米,重量750克,平均噪音空閑模式26dBA、尋道模式0 34dBA、尋道模式3 30dBA,功耗讀寫10.7W、空閑8.2W、待機1.3W、休眠1.3W。

特色技術:

1、雙處理器:加速硬盤內部處理速度,提高性能。

2、兩級驅動伺服系統(Dual Stage Actuator):擁有兩個讀寫臂的磁頭定位系統,可提高磁頭在數據磁道上的定位精度,其中第一個讀寫臂利用傳統電磁驅動原理提供粗略定位,第二個則利用壓電驅動原理進一步調整磁頭位置,提高精確度。

3、IntelliSeek:計算最合適的尋道速度,降低功耗、噪音、震動。

4、StableTrac:將盤片旋轉馬達在轉軸兩端都進行固定,能有效降低震動,提高尋道讀寫的穩定性。

5、NoTouch:非接觸斜坡加載技術,保證磁頭不與盤面接觸,減少磁頭和盤片的磨損,更好地保護工作狀態中的硬盤。

企業級型號則是RE4系列,編號“WD2003FYYS” ,各種性能、物理參數均與WD2001FASS完全相同,不過也有自己的一些特色,比如平均故障間隔時間120萬小時  (A片有保障)、動態節能技術Active Power Save、增強型旋轉加速伺服系統(RAFF)、多軸震動傳感器、壓力傳感器 、第三代動態飛高(DFH)、限時錯誤恢復(TLER)等等,還經過了大範圍、更嚴格的測試過程,以確保企業級客戶所需要的長期穩定性。

Caviar Black 2TB WD2001FASS現已開始全球零售上市,建議零售價299美元,享受五年有限質保。RE4 2TB WD2003FYYS也已供貨給OEM廠商,價格未披露,也是五年質保

向我的128 MB cache夢想邁進了一步。

64MB CACHE雙I/O,不知道如何,只知道暫時昂貴,但總好過高速SSD死得快

WD® LAUNCHES HIGH-PERFORMANCE, 7200 RPM 2 TB HARD DRIVES FOR DESKTOP AND ENTERPRISE SYSTEMS
WD Caviar® Black™ and WD RE4 Four-platter Hard Drives Set New Benchmarks in High-Feature, High Performance Storage

LAKE FOREST, Calif. - Sept. 1, 2009 - WD (NYSE: WDC) today announced that it is now shipping desktop 7200 RPM 2 TB hard drives and is qualifying with OEMs enterprise-class hard drives based on WD's 500 gigabytes-per-platter technology. The popular family of WD Caviar Black drives, now led by the new 2 TB capacity, is perfect for gaming, high-performance desktop systems and workstations; while the WD RE4 2 TB is suited for servers, network attached storage and storage networks.

High-performance hard drives by an industry leader in performance, WD Caviar Black and WD RE4 2 TB drives combine 7200 RPM spin speed, 64 MB cache, dual stage actuator technology, SATA 3 gigabits per second (Gb/s) interface, and an integrated dual processor to deliver ultimate performance in a maximum-capacity drive.

"WD Caviar Black 2 TB hard drives maximize the features and functionality of power computing applications such as gaming, photo editing, user generated multimedia and video," said Jim Morris, senior vice president and general manager of WD's client storage systems. "With the selection of WD Caviar Black hard drives, WD desktop customers receive the best possible mix of capacity, performance and reliability that is required for intense desktop computing."

"Specifically designed for enterprise-class applications, WD's RE4 2 TB drives incorporate the best combination of features, optimum performance, and superior reliability that customers have come to expect from WD," said Tom McDorman, vice president and general manager of enterprise storage solutions for WD. "Our enterprise products are directly aimed at customers who require additional features and extensive testing that are necessary for high-end enterprise environments."

WD Caviar Black 2 TB and WD RE4 2 TB hard drives feature the following:

    * Dual processor - Twice the processing power to maximize performance.
    * Dual actuator technology - A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy.
    * IntelliSeek™ - Calculates optimum seek speeds to lower power consumption, noise, and vibration.
    * StableTrac™ - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations.
    * NoTouch™ ramp load technology - The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit.


Additional Features for WD RE4 2 TB Enterprise Hard Drives
WD RE4 drives feature 1.2 million hours MTBF, Active Power Save™, enhanced RAFF™ technology, multi-axis shock sensor, native command queuing (NCQ), pressure sensors, third generation dynamic fly height, time limited error recovery (TLER), and an extensive and enhanced testing process to ensure long-term reliability for demanding enterprise applications.
