Very lost, trying to buy a DAS.

[ed]

Terramaster just like other DAS or NAS brands use the same RAID software. Recovering either of them would make no difference.
If you get something with hardware RAID, you will more likely lose your data if the controller fails. Simply because no RAID data is stored on the drives themself.
RAID1 will surely recover faster than RAID5. But both will recover.
The choice here is about speed and capacity.

Also, consider disasters like flood/fire/theft.


I hope this helps.
