Question

System administration

The task is to make a 10-15 TB NAS server. I want to have a raid. Audio, video files will be stored and they will often be played over the network. What is the optimal raid to choose? And which is better, more HDD but smaller volume or less but larger volume to take?

Answer 1

Need RAID, it all depends on the required reliability. The more reliable, the more useful volume you lose.

average will be RAID5 with 4TB disks. Not the fastest, not the slowest, 1 disk fault tolerance, relatively little wasted space
5 disks needed, total 16TB

Answer 2

RAID5 or RAID6 The
second good question is the choice of file system. If for large files with video - you can look towards XFS / ZFS
