How does the system work?

Question

I recently heard about StableBit DrivePool as a way to turn multiple volumes into a single volume in File Explorer. I wanted to ask how this was done; is the process that is used closer to a RAID-0 setup, with no redundancy, such that if one drive fails, all the data is lost, or is the setup such that if a drive fails the data on the failed drive isn't lost?

Have you tried reading https://stablebit.com/?

Anyway, DP combines volumes into a large NTFS volume. It can have redundancy if you want. Either for the entire "Pool" or just certain folders therein. If one drive fails, the most you can lose is the data on that one drive. The data on the other drives will still be available. If all was redundant (we call that x2 duplication) then the Pool will reduplicate the lost files, provided you have enough space.

Each drive you add to the Pool is not exclusively for the Pool. It will create a hidden PoolPart.* folder within which the Pooled files will be stored. You can use the rest of the drive as well outside of the Pool. DP simulates a NTFS drive but it also uses plain NTFS on the drives that are part of the Pool so any recovery tool that works on NTFS will work.

x2 duplication is a bit like RAID-1 in the sense that it requires twice the space to store data. Parity/checksums are not supported by DP.

You might be able to learn a lot actually from just reading a few threads here on the forum.
