PCI IDE host adapter card

Questions about adding more IDE channels...

I'm considering getting a PCI IDE host adapter card (HighPoint Technologies Rocket133 Host Adapter). The short specs are:
Host side interface
32bit 33/66 MHz PCI

Device side interface
Ultra DMA/ATA133

The hard drive I want to use this with is the Western Digital WD1200JB. It states that it can do "Mode 5 Ultra ATA 100.0 MB/s ".

Here's my question: How fast are my PCI slots? Gigabyte says they're PCI 2.2 compliant... (what does this mean?) Is the PCI slot slower than 100 MB a second transfer rate? If so, will their be a "bottleneck" between the PCI card to motherboard?

How do you test the speed of a PCI slot?

Does anybody any other ideas on how I can add more IDE channels to my system? Should I be looking at a RAID (RocketRAID 404) card? I thought about going SCSI, but I don't have the finances for this.

Any ideas are appreciated!

The PCI bus runs at 33MHz and can handle 133MB/s. But the drive will almost never read/write at the speed. The actual speed will probably be around the 40-50MB/s.

That is also why the modern Serial ATA with 150MB/s bandwith is useless on the PCI bus (in speed that is... those small cable are very handy).

My dual-PSU PC is so powerfull that the neighbourhood dims when I turn it on
