Yes that's a reasonable route, but not for me. Here are my reasons:
1. RAID is not a backup.
That is a common misconception and there are important differences. RAID is redundancy that protects against HDD failure only.
For example if I do a bunch of management and screw things up, or accidentally erase the drive or something, with a backup available there is something to restore from. With a RAID, the screwups are instantly mirrored in real-time on the redundant drive. Admittedly my main goal for backing up IS to protect against HDD failure, which RAID does, but I'd rather have a backup than RAID.
I've done RAID twice before and the complexity adds its own problems. For example the RAID enclosure itself becomes a single point of failure. If it fails, you lose access to both drives. In some cases RAID can also have weird formatting that prevents it from being usable if you hook up a drive directly to the host.
With separate USB drives, if one HDD enclosure fails, the other is still working. And both drives have formatting native to the host device.
2. Existing capability / Simplicity.
The Zidoo already features NAS
. Why would I buy another one? I already have one 10TB USB drive. I plugged in the drive and enabled SAMBA. BAM...network attached storage. Simple and clean.
Buying another NAS means spending more money duplicating something I already have. It means another device to power, learn, configure, troubleshoot, and maintain with updates. I see a lot of negatives and very little benefit.
I'm looking at simply adding a second USB drive to the Zidoo. That's much cheaper than a NAS with an equivalent size internal drive.
So having been down this road before, this time I'd just like to have a second drive and some app to do a periodic backup from one to the other.
