Slow DVD/CDROM Performance

[RWise]

I have an A-Open 1040 Pro (10X/40X) DVD ROM drive. I have recently downloaded SiSoft Sandra 2000 and have benchmarked this drive, it was reported as having 4X drive speed and 2X DVD ROM speed. Is this likely to be a faulty drive or is the bottleneck somewhere else on my system. The drive appears to work alright as in reading and installing data and playing DVDs. DMA is installed and I am using the latest 4in1 VIA drivers.

I'd recommend downloading CDSpeed99 for benchmarking your CD-ROM, DVD, and CD-RW drive performance. I would also try comparing the benchmarks between the default Win98 IDE Busmaster Drivers and the VIA IDE Busmaster drivers.

P.S. Here are some benchmark results that I got when I compared the CD-ROM drive speed with the AMD/VIA Busmaster Drivers vs the default Windows 98 SE Busmaster Drivers.

AMD/VIA Busmaster Drivers with an Aopen 48X CD-ROM drive and DMA enabled:



Windows 98 SE Busmaster Drivers with the same Aopen 48X CD-ROM drive and DMA enabled:

Results from CDSpeed99:

Speed
Average=13.96x
Start=16.77
End=12.92x

Seek Times
Random=75ms
1/3=91ms
Full=127ms


Results from DVDSpeed99:

Speed
Average=1.48x
Start=1.98x
End=1.78x

Seek Times
Random=91ms
1/3=102ms
full=162ms


These figures are using the VIA drivers. When I tries the Win98 drivers the results were more or less identical.
