Raid 1 is mirroring. &nbsp;You CAN do this with 2 hard drives. &nbsp;Reliability is excellent because it writes the same data on 2 drives, so both drives would have to fail before losing data. &nbsp;Performance would be the same as a single drive. There is no performance increase with Raid 1. &nbsp;You would not, however, be able to use your current drive as one of the drives because when you create the array, it deletes your partition. &nbsp;However, you could make a ghost image of your drive, install the card and both drives, create the raid array, and then put the image back onto the raid array. &nbsp;

I'd like to get a RAID 1 configuration running on a SC430, and I'm reading that either I can't do this with only 2 hard drives (because it has the OS on it??) and that the performance and reliablity is horrible. <br />
<br />
If there's any truth to that, I'd like to know of a RAID card for the Dell SC430 that will not consume one of the two plain PCI slots. &nbsp;I guess that only leaves the PCI-E slots (please confirm this before providing a suggestion!). &nbsp; I'm looking for a good card under $150. <br />
<br />
Thanks!
