Help with RAID? I have 6 x 1.6TB Solid state drives in a proliant. It will hold a few large databases. Raid 50?

How do you think i should configure these disks?

Raid 50 for 4.8 TB useable? This will cut it close to being full.

Raid 6 for 6.4TB useable? The database is analytical and is almost all read, no write.
