I had a drive fail on my Synology NAS just a couple of weeks ago and took the opportunity of expanding capacity during the replacement. Synology uses a "hybrid raid 1" configuration so I don't know whether it's a generic capability or just for Synology. The NAS had 2 x 2TB drives and I bought 2 x 3TB WD Red NAS drives. I removed the failed drive and replaced it with a new one and after a few hours it synchronised and I had 2TB of storage available to me. After letting it settle down for a few days I replaced the 2nd drive and after a few hours of synchronisation had 3TB of storage space. Couldn't have been more straightforward.
