SCSI HD vs IDE HD???

[ModelM]

I know the SCSI vs IDE debate has been done to death, but this question is more specific to my PC. Right now, I have a Fujitsu MAN3184MP SCSI 18.4 GB hard drive, and a 120GB IDE Hard drive. Unfortunately, I'm not 100% sure of the model, but I think it is an IBM. Anyway, my computer detects it as a IC35L120AVVA07-0, whatever that means! My SCSI card is an adaptect 2940u2w. Even though my hard drive is ultra160, I was under the impression that my performance would not be affected running it at 80MB/s (U2W). Also, the SCSI hard drive is about a year old, and my IDE is about 3 months old. Anyway, I would have thought that the SCSI hd would have blown away the IDE in terms of performance. But actually, it appears that my IDE HD is faster. Is this normal? Is there a driver or something I could install to boost the SCSI performance?

The Fujitsu MAN series drives are faster than that IBM drive, in all areas - throughput, access latency, seek times. However, some Windows flavors suffer quite badly from SCSI controller registry screwups. There has been wild discussion about a surprising lack of SCSI performance in W2K and WXP all over the place - hook yourself up to those threads, and find a solution that works for you.

The IBM drive is a 120GXP.

Anyway, there has definitely been a lot more work on refining IDE driver performance than SCSI driver. There is quite a bit of tweaking that can be done in that department. I suggest looking for newer drivers and tweaks for your SCSI controller.
