謝謝各位回應！
硬碟部分，因為是測試機，所以資料不重要
該機器主要的用途有點像路邊監視器
至於這張卡為何這麼貴...
紐西蘭原廠那邊制訂的價錢一開始就是這麼貴
卡的用途是：封包擷取與傳送
號稱
*100% data capture
Security can only be assured if 100% of all Network data is inspected
Standard NICs drop significant amounts of data
This is especially important to security agencies and lawful intercept companies

*CPU Off Load
Standard NICs swamp the CPU with programming demands
Endace Interface Cards off load this task allowing application programmes to run much faster
The user's experience is a much faster systems that doesn’t crash or lock up

*Full line rate
Data volumes are ever increasing and any restriction in the network acts as bottleneck
Standard Network Interface Cards are such a bottle neck often restricting the system performance to half or a quarter of the available bandwidth
Endace technologies ensures maximum use of the available bandwidth as it removes all bottlenecks

*Hardware acceleration of software
Additional processing for the most demanding customers
Pre-processing tasks like filtering, searching, reconstruction and matching greatly increases system performance and throughput and is now a must have for High End Network Security Systems
