macklin01 said:Agreed, IDE master and slave share the speed on each channel. But as I understood it, each of the following were independent:
1) IDE0 (master and slave share)
2) IDE1 (master and slave share)
3) PCI (all slots share)
Is that right? Thanks! -- Paul
The majority of high performance GFX cards sold nowadays are AGP anyway so this isn't a problem. The lower spec gfx cards won't push the PCI bus much. What will though is a couple of WD Special Editions in a RAID0 array....there's ~90Mb/s used straight away on a sustained transfer. If you do any sort of video encoding using dedicated Video hardware and a RAID array than things can get crowded .
macklin01 said:That's right. You can never have higher transfer rates on the PCI / IDE bus than 133 MB/s. In reality, though, this isn't what's holding up disk I/O; it's the disks themselves, since they can never handle sustained transfer much above 70-90 MB/s on some of the fastest, fastest SCSI drives. -- Paul
