Enough Bandwidth?

[The Halk]

I have a PCI-E 1x SATA RAID card in. And I'm thinking of doing a hard drive upgrade.

I run a 150GB Raptor as my main drive, and this will remain as it is. I don't want RAID on the boot drive.

However, a huge bottleneck on the PC is hard drive access when it's working with huge (GBs in size) files.

So I wouldn't mind having RAID0 on the new drives.

I'm thinking 2 TB should be enough, so I'm looking at 2 of the new 1TB Hitachi drives.

Will the bandwidth on a PCI-E 1x card be enough to handle RAID0 on two of these?

Previously I've had problems with corruption in RAID using nForce4, so I don't want to use the RAID on the motherboard, in addition as long as I keep the card then it doesn't matter if I upgrade the motherboard, the array will stay in tact.

I'm trying to run my drives cooler, which means leaving a bit more space between them. I've got racking for 8 of them. I'd like to get rid of 6 of those and replace them with a couple of 1TB.

I realise I could lose everything if a drive fails. I can live with that though. Stuff can get backed up to DVD if I'm keeping it. I have a 20MB broadband connection and a Giganews subscription, so I do go through a lot of PAR repairs, and unRARs (of Linux distros of course. No piracy).
