個人建議你不如買 WD Raptor.. 單顆
RAID 0 對日常桌上電腦使用所增加的效能有限，卻增加資料損毀的機率 (一個壞，兩個資料一起壞)
請參考這篇文章

節錄一小段
Again, RAID 0 does have its advantages in a handful of key applications and uses where data files are huge and/or data requests are highly sequential in nature. Data requests are not highly sequential, however, in typical desktop productivity and most gaming usage patterns, the most often cited in "Help me build my RAID 0!" posts.
The point? Dont assume RAID 0 offers increased performance for all or even most applications... and dont assume that transfer rates reflect application-level performance.
也就是說，不要以為 RAID0 可以很明顯增加你系統效能，而且也不要以為高傳輸速度 = 系統程式應用效能
好的硬碟是要能夠 低 搜尋速度 高 內部傳輸速度 高 I/O 處理速度
