If a drive fails, will I have full access to my unRAID array?

Yes, BUT … If a drive fails or is missing, you will still have full use of the entire array, including the contents of the failed or missing drive, just as with any similar RAID system. You can copy files from all drives including the missing one, AND you can even copy files TO the missing drive, although performance will be considerably slower. The unRAID system is designed to reconstruct all of your data and the file systems, IF the parity info is being fully maintained with all of your data drives. HOWEVER, any time you are running without access to the failed or missing drive, any time you are running without all green status balls, you are UNPROTECTED against further drive failure. If a second drive fails, you will probably lose the contents of BOTH failed or missing drives! It is strongly recommended to resolve the problem with the first drive as soon as possible. As a cautionary tale, please see “Stopped. Invalid configuration. Too many wrong and/or missing disks!” .
