Question

Server equipment

What is the best way to divide server disks into partitions, folders for such a configuration ( SSD 2x240GB HDD 2x2TB SATA ) if the server will be used for one site?
The site will have a folder where users can write their files. Where, on SSD or HDD, is it better to place a folder of user files, server logs, site? Maybe something is better to put on the SSD, and something on the HDD? Backup is going to be stored on the HDD and on the hosting backup server.

Answer 1

SSD is best to store the system itself, and the cache.. For fast loading and work.
