RAID 1 always limits your capacity to the smallest drive in the pair.
So, if you want to continue using RAID 1 and increase capacity, you'll
need to replace both drives. *By the way, RAID 1 does a decent job of

Also, if you simply "clone" the drive or the RAID array with most
software, it will set the size of the new array or drive partition to
the old size.

If you've replaced both drives with a new (larger) set of disks (which
should be identical in a RAID 1 array), then you will probably need to
rebuild the array (or partition) to the larger size. Note that
rebuilding the array can destroy the data on it - this very much
depends on the software and tools you use to reconfigure the array.

Good luck, take care,
