Ok, so this is like software RAID5? This is where parity data fits into the picture? Right, so there is a way to store but not protect against drive failure. I will find these more experienced people. How does the data on each drive on top of parity function? How many drive failures can the system handle? One or more? I suppose this depends on what resources are available for parity? My question comes from what I understand of drive pooling which is just file level copies on separate drives. So no versioning like with Freenas/ZFS. I have dropped FreeNAS because it is apparently necessary to setup the final system and it is also difficult to grow storage. Unraid seems more lightweight and flexible. I will read more about parity. This is a kind of error detection?

Currently reading.

@techsperion, thank you for all this very useful information. Would I be correct in saying that Unraid stores a given file as copies on multiple drives? Also, is it possible to skip copies or redundancy for some unimportant files that I can afford to lose?

Hi, I'm in the process of building a NAS at home for my storage needs. I take a lot of photos and want redundancy to prevent file loss. It would also be great to have a media server and backup my smartphone remotely. Now, some questions. How does Unraid save data exactly? Does it use the principle of drive pooling? Can a single drive be taken out and read like a normal one? How is data loss prevented? What advantages would it have over Stablebit Drivepool? Thank you in advance for your insights.
