硬碟rpm對轉檔之影響

大概分享一下

環境 :
HDD : Seagate 500G 7200rpm <-> WD Raptor 80G 10000rpm
CPU : [雙核心 & 四核心] @3.6GHz
DVD : Monster House 7.67Gb --> 4.35Gb

===

雙核心 = 最高Rate : 7xxx KB/s
Seagate --> WD Raptor

WD Raptor --> Seagate

四核心 = 最高Rate : 11xxx KB/s
WD Raptor --> Seagate

Seagate --> WD Raptor

Conclusion :
CPU核心影響大過HDD rpm轉速 (費話)

Dual ST 7.2k -> WD 10k : 20'31"
Quad ST 7.2k -> WD 10k : 12'59"

Dual WD 10k -> ST 7.2k : 20'53"
Quad WD 10k -> ST 7.2k : 13'07"
