**『無』配備自由墜落感應器**
自由墜落感應器 - 這是作為一層額外的保護層,假如硬碟(或裝有這些硬碟的系統)在使用中掉下,WD 的自由墜落感應器(free-fall sensor)會偵測到硬碟正在墜落,並在少於 200 毫秒的時間內,將磁頭停放好,以防損毀和數據遺失。

結論:
1. 比對2.5 吋320G WD WD Scorpio WD3200BEKT黑牌系列 , 讀寫效能約提升18~20MB/S
效能上:最大寫入100.9MB/S,最大讀取101.9MB/S,
平均寫入=79.2MB/S,平均讀取=80.0MB/S
2.WD 5000BEKT 500G與Seagate Momentus XT 500G相比約小輸上1MB/S~3MB/S,效能上在伯仲之間
3.實際光華集中商圈尋訪價位與網路上詢查尚未看到銷售蹤跡
