This would be one way of getting the larger drives in place but you will
still have a 500GB logical drive and that's all the OS will see so you
can't use disk management to use the rest of the room. The RAID
controller might have an option to enlarge the logical drive or create a
second logical drive which the OS can see. If not you will need
partitioning software to enlarge the logical drive or create another
partition on that logical drive. I've used Acronis to enlarge the
logical drives before.

As I understand your setup, your disks are mirrored in "the hardware". That being the case, I would take one (1) of the (I'm assuming) 1-TB drives and swap it with one of your 500-GB drives letting the hardware mirror the partitions. (You may need to take the additional step of synchronizing the RAID.) This will, of course leave 500-GB (give or take) of unallocated space on the new drive in the array. Once the array was synchronized, I would then repeat the procedure by swapping out the other 500-GB drive for the other new 1-TB drive, and allow the array to be synchronized at the hardware level. If all goes as I think it might you should now have a RAID-1 array with C: drive showing the same amount of space as before, once you open My Computer and check the properties of C:. The next step I would take if this turns out to be the case, would be to right-click My Computer, then left-click Manage. Click on Disk Management under Storage, and use Windows to expand each partition to some portion of the "unallocated space" that should show up. (I'm assuming that each of the 1-TB drives has been formatted.)

My current drives have three partitions; I'd like the new drives to have the same content in the same partitions, but to enlarge two of the partitions slightly and make the third partition at least 400 GB.
