How To Replace/Upgrade Dynamic Disk?

[twodaend]

Currently I have a PVR system based on BT4. My shows are recorded to 2 80GB drives that are dynamic to look like one 160GB drive. I was wondering if it is possible to upgrade one or both 80B drives.

For example I have a 250GB drive that I would like to use and replace one of the 80GB drives, thus giving me about 330GB worth. I really don't just want to add the 250 to the existing 2 80's because I don't have any more connection in the case and all of my PCI slots are used so I can't get a Promise card.

Is this at all possible?

Thanks for the help

if you can temporarily connect the 250GB drive, couldn't you copy everything to it, remove the current spanned volume, upgrade the 250GB to a dynamic disk, and then add to it with one of the 80GB drives?

I figured that would be a way to do it. I think my original line of thinking was something like a RAID 5 setup with a hot spare. I just started looking at the Promise card for some idea on this, possibily the FastTrak S150 SX4.
