(esp Toshiba 3401b) Summary: Speedy CD-ROM? I'm not seeing it! Message-ID: <1993Dec31.202224.813@cs.wisc.edu> Date: 31 Dec 93 20:22:24 GMT Sender: news@cs.wisc.edu (The News) Organization: U of Wisconsin CS Dept Lines: 23 Does anyone have any experience with double-speed CD-ROM drives? If so, what sort of bandwidth are you seeing from the drive? The reason I ask is that I recently purchased a Toshiba 3401b, which is supposed to achieve 330Kb/s. However, when I use "dd" to read from the raw device, I get only about 200Kb/s. Is anyone else getting better performance from a similar drive? If so, what sort of speeds do you see when you execute: dd if=/dev/cd0d of=/dev/null Incidentally, the Toshiba is attached to an Adaptec 1542b card...
