方法是有的,但是就是要一點計算,只是估計而已. 因為影響的因素很多,比如內外圈等等,另外還有disk fragment的影響.所以user data transfer rate不是廠商可以當****數據的. 那篇文章裡還有很多說明,看了就會明白. |

不是95MB/sec 是1:10 不是1:8 跟SATA宣稱1.5Gb/sec是150MB/sec而不是188MBsec相同道理 |

8bits = 1byte沒變 可是也有10bit = 1byte的領域,詳情怎樣我不知道,不過我這幾篇留言有信心不是在胡扯. |

就像小強大說的。  Serial ATA 抓倒數第2個"Serial ATA 1.0a Specification" 我也有點疑問才找到這個， 不過，英文差，只找圖表看沒深入細看。 內部傳輸率是除以10bits或8bits看官方用法較準吧， seagate的Datasheet這個是95MB/s。 此文章於 2004-12-22 08:03 AM 被 takahara 編輯. |

你只是誤解....不是糊扯......  計算機的領域沒聽說沒看到有出現10bit = 1byte的.... 最基本的換算搞錯...計概會被死當吧......

別吵了啦
難道一定要在吵架的氣氛中討論嗎? 10 bit = 1 byte 8 bit = 1 byte 去 GOOGLE 裡面找就好了 |
