PCI-e 1x. Max bandwidth?

I'm going to be ordering a new RAID controller as soon as OCUK get them back in stock.

Was just woundering what the transfer speed on an PCI-e 1x port is, because the RAID controller would be using it.

Thanks.

Done a quick search and found this on Wiki

Is it right that a PCIe 1x port can do upto 8 GB/s ?

No, 500MB/s for 1x PCI-E, which scales up to 8GB/s for a full 16 lane slot

Kool thanks mate, so I should have no problem running a RAID0 from it then

nope... but RAID5 with enough discs might be a different matter

I get 120MB/s or so with 2 in RAID0.
