DOA Hard Drive
First time I've ever had a hard drive DOA. Was upgrading drives in my home server, as the drives were a bit old and wanted to increase space. Five years ago, said I'll never run out of space, LOL. ...

I wouldn't run RAID-5 with such a large array, at least not unless you have good backups or don't care if you lose the data.
RAID is NEVER a substitute for backup !
Admittedly, my RAID array only gets backuped up once a week.
Correct!
While RAID levels above RAID 0 provide redundancy of the drives themselves, it however, does not provide redundancy for the RAID controller hardware nor the PC hardware.
A failure of the RAID controller can deal a fatal blow to the data on the drives especially while the drives are being written to.
Additional backup methods are essential for any data you deem important or critical.
Good practice is using several types of backups for good measure, for personal use, a simple external USB hard drive will work fine but should consider one step further and use at least two different external USB drives. Alternate between the drives every other backup.
I have had external USB hard drives fail which is why two different USB drives are important..
