    I currently have two harddrives set up as a raid0 on my desktop pc. The raid controller is onboard nforce (like a firmware raid i guess). I am setting up a small server thought that I would like to move the raid over to (it will need a sata card as it only has one IDE slot (its a asus pundit-s - fairly old hardware). Can I do this without dataloss? The data cannot be lost and the raid is bigger than any other storage I have available (1tb).

    The only time I've ever managed this was when I shifted an array that was running one one Silicon Images controller to another controller that had the same chipset on.

    If you're configuring a server, hopefully only for testing purposes, I'd really advise against using RAID0 - your heading into a whole world of pain if one of those drives fails, or the controller/power feed has a glitch, and you don't have a back drive image (and software that can sucessfully restore to that RAID controller).

    For the cost I would plump for seperate hand drive from somewhere, either new or a tested second hand one.

    Well I could buy a sata drive as they wouldn't be too expensive. A second question:

    if I buy a PCI SATA controller will it be worth it, the mother board is quite old like I said: I think the FSB is 133mhz (for reference). Would I benefit from using SATA II Drives or would they be bottlenecked somewhere.

    Should be possible with software raid but to move hardware raid, you need to move the raid controller as well.

    Standard PCI buses run at 32bit / 33Mhz giving an available throughput for the whole bus of 133Mb/s, your PCI slot that the adaptor is jacked in to shares that with the other PCI devices.

    So in answer you'll be bottled necked by the bus if, and only if, you're pulling a large throughput from the drive, remember that most modern drives are still around the 70-90mb/s average (more details over at Toms). If you've not got a lot of other items on the PCI bus then it should be fine but you may see better with a native onboard controller but unlikely to be noticed during normal use.
