磁碟本身可用空間要大於等於2GB,以讀寫1GB的資料量的時間來反推讀寫速度, Sequential Read x 0.1 + Sequential Write x 0.15 +4KB Random Read x 1.0 + 4KB Random Write x 1.5 +4K-Thrd64 Read x 1.0 + 4K-Thrd64 Write x 1.5 = Score
Read = Sequential Read x 0.1 + 4KB Random Read + 4K-Thrd64 Read Write = Sequential Write x 0.1 + 4KB Random Write + 4K-Thrd64 Write
