Consolidate storage space

[JimmyDB]

hi,
what is the usual way to concatenate multiple HDDs for the movies in an Ubuntu server? RAID0 is dangerous after all with about 5+ HDDs, with other RAID versions I lose space. 
Is there anything in between, if one HDD is broken only the data of that HDD is missing?

thanks!

I personally use snapraid and mergerfs and haven’t had any issues

You may lose storage space, but your choices are maximum space with zero redundancy or less space and able to survive a failed drive. Hard drives do fail, sometimes with zero warning, so having the ability to survive drive failures is well worth the "lost" space. The best trade-off in terms of space not available for data is RAID5 or RAID6; RAID5 (minimum of 3 equally-sized drives) can survive the loss of any single disk, RAID6 (minimum of 4 equally-sized drives) can survive the loss of any two disks and rebuilding the array after a failed disk is less error-prone.

mergerfs looks suitable. Do you also use the "arr" programs with it?
