Pci Sata Raid

[highrisk]

I recently purchased two additional SATA HDD's to add to my RAID array, already consisting of two 120GB SATA HDD's.

My motherboard only has two built-in SATA RAID channels, so I had to purcahse a PCI SATA RAID controller with 4 channels.

Then, I got to thinking about the PCI bandwidth speed.
Would that lower the speed of my disks, from taking them from two on my motherboard, to four on a PCI SATA RAID controller - since it's going over PCI?

No, it wont. The speed limit of PCI is a lot higher than SATA (pci - 132MBps to 1GBps, SATA - 150 MBps) and the new pci will be either 512 MBps or 1GBps. Since sats is capped at 150 (unless it is SATA 2, which I dont know the speed of) and pci is capped at 1GBps, you shouldnt see any problem.

How can I see how fast my PCI channels are?

 

[Him]

Not sure. You can try SiS Sandra but I'm not sure if that will tell you. i dont know where to find it either, I remember I found it by accident a long time ago.

Cause the Windows Instalation took longer to load with 4 drives in RAID 0 throgh PCI RAID, than 2 drives in RAID 0 through Motherboard RAID. That's why I was wondering.

Its just possible that it goes slower with 4 drives instead of 2
