你..... 看得懂英文嗎? 看不懂可以問.

The Quantum Bigfoot brand was a series of hard disk drives produced by Quantum Corp. from 1996 through the late 1990s. The Bigfoot series was notable for deviating from the standard form factor for hard drives. While most desktop hard drives at that time used a 3.5-inch physical format, Quantum Bigfoot drives used a larger 5.25-inch form factor more commonly seen in older hard drives, CD-ROM and other optical disc drives. This form factor allowed Quantum to increase the capacity of their hard drives without an increase in data density, thus lowering costs compared to a 3.5-inch drive with the same capacity. It also allowed manufacturers and owners to install the hard drive above or below the optical ...

時間太久,沒去找資料。
你拿一代大腳 transfer rate、二代大腳的 access time......

實際上使用,除非當磁帶機純資料碟一樣循序讀取,否則隨機讀取受 到 access time、
cache 大小影響很大。

1998年下半年三代大腳才算比較勘用

和大腳第二個產品迅猛龍相比,TS硬碟平均搜尋度由原本的12ms提升到10ms,緩衝區為512KB,而最主要的突破還是硬碟單碟片容量的加大,由原本的2GB到現在的6GB。

2000年上半年,Seagate 入門 SCSI 7200轉怪魚9G ,6ms,2MB ,24MB/S。
(16G 4MB cache )
IDE 7200轉的,單工慢一點,多工慢很多。

如果傳輸率慢 1/3,access 慢1/3,cache 只有1/n ,每一樣都慢一點,
實際上用起來會只慢1/3?
(1代快大腳 cache 128KB)

實際上3代大腳總合表現評測還是慢,當年DIY 組機的,有玩遊戲的人都不可能用它
當系統碟。當時我的電腦最多時大概4顆 IDE ,2顆 SCSI,只有IBM、Seagate的。
大腳連看 A圖都比人慢……acdsee 還要等一下,人家都翻好幾張了……
