謝謝連結, 使我更了解 "微軟", 剛剛做一個簡單的測試
將 712M的檔案(有243個小檔) 以碼表計時作 copy 測試.

SCSI 萬轉硬碟
MAJ3182MP 18G
MAN3367MP 36G

IDE 7200 轉硬碟
WD 120JB 120G

S-ATA 7200 轉硬碟
HDS722525VLSA80 250G*2

SCSI to SCSI
18G to 36G :54"
36G to 18G :1'03"
36G to 36G :1'26"

IDE to SCSI
120G to 18G :1'29"
120G to 36G :45"

IDE to S-ATA
120G to 250G :25"

S-ATA to SCSI
250G to 18G :1'31"
250G to 36G :47"

S-ATA to IDE
250G to 120G :40"

真是災難, 開來微軟未解決前先用SATA當系統碟.
