How much data is retreivable form one disk in a raid 5 array (gregtech.eu)

If i would, hypothetically, have a few different drives in a raid5 array in different physical locations, and one was seized, how much data could be reconstructed from that drive?

(I was reading about A/I and their R* system a bit, and this semi-related idea came to mind)

That would depend a lot on the configuration.

What filesystem was used?

How full was the array?

Did you configure encryption?

What kind of data was stored on the array?

To be frank, I have no idea about this, but all of the above are things that affect the raid array.

In cases like this, you need to plan for the worst, so you are prepared for it if it happens.

It would probably be an ext4 fs and lets say the array is 20% used.

In any real world application i would have encryption, but for the sake of this hypothetical, i don't.

And about the data, it would probably be a mixture of big and small files like text files, videos and images.
