I have a server with 2 x 1T HDDs.
In the next 4 months I intend to make an upgrade with another 2 x 2(3)T HDDs.
Which is the optimal configuration using RAID 1 (number of partitions, size of partitions), for an email/file server starting from two HDDs and extend later with another two HDDs?
It’s ok how NS make the partitioning?
I read a lot of articles and I’m confuse.
