Good to hear. It'll help us to recommend a configuration to you

It makes sense to split up your storage into multiple bricks, atleast one
per disk. This way access can proceed concurrently on many disks.

Configuring GlusterFS for optimum performance would have to be done knowing
the kind of load you expect. What sort of applications will be running?
What are their data access patterns? (mostly reads? mostly writes? small files?
huge files? etc.)
Do you need redundancy (replication)?
