A single drive would be safer compared to RAID0, because with RAID0 if a drive does go, you lose all of the data stored on that drive.
Guessing that this is a 2-drive unit you have what 8TB max in this unit (2x4TB raid0)?
Just purchase a single 8TB drive.
A single drive is not safer because if the drive goes you still lose all of the data on that drive.
With a single drive, you have a lower chance of failure (raid controllers, drive issues whatever) And a single drive is easily copied from for backup purposes.
You get an equal size drive, and robocopy or DD all of the data.
Backup done.

It is because in raid 0 any one of the drives die you lose all the data... 2 drive raid, twice as likely for a failure.
Ah ya fair enough. I was just thinking you still only need to lose one either way. It's been a long day.

Turns out neither of the two drives have a reported bad sector in SMART. The only thing I can see is that disk 2 has SMART value "current_pending_sector" of 1. Apparently this means there was a write or read issue and it will be marked the next time it attempts to be accessed.
As far as I've researched, having 1 pending sector issue is nothing to worry about.
I just wonder why it didn't handle it automatically and further, wonder if it's striping that somehow prevented it from auto-fixed the sector. I may just have to use these drives separately and skip the striping.

@guyinpv i would agree. Nothing to worry about.
