I have a question about creating volumes on a 6 bay nas server with 24 TB of space with RAID 5
we are a school and we want to store all the school's data on the nas server.
like student's and teacher's temp folders, videos, backups, department's data, learning materials, archives.
how many volumes should I create?
is it advised to create one volume?
should I create a volume just for backups?
It is just 6 bay nas. For better space efficiency, you'd better using one volume. You can use multiple partitions on single Raid volume to serve users.
On the other hands beware that, if one of the disks fails, it can take more than a day to rebuild raid5 volume. And risk(or probability) of raid5 to fail during the rebuild is too high. Moreover, I/O speed of raid5 is rather poor and I doubt its performance is enough for your school. It's why people recommend to avoid Raid5. Raid10(for better performance) or Raid6(slow but much safe than raid5) will be much better choice.
