Question using multiple drives

[steveameba]

I have a dedicated server with 2x400gb ssd and 2x3tb hdd both raid1

how does plesk use these drives? at the moment I only have the 400gb ssd's configured so I cant see the 3tb drives yet, but to me (who has little idea really) it looks like plesk and all the website data etc will go in the 400gb, and if it gets filled it wont use the additional drive,

Is it possible to assign the data from a site to one of the drives in plesk? at the moment it is in /dev/sda3
if not possible in plesk then can it be done in the sites software? so for example if i install owncloud it will go into /dev/sda3 but can I tell owncloud that its data is in /dev/sda4?

Plesk will use that partitioning that you define in the file /etc/fstab
For example, for mail/web/db data you can define /var partition located on SSD drive. For /tmp partition you can also use SSD and HDD for / partition.
