I am using an Areca-1223-8i to run 8 4TB Hitachi 7K4000 Ultrastars in RAID 5. It is used for Blu-ray and DVD iso's so performance isn't necessarily the number one priority. I like that RAID 5 offers the most usable space but from what I read online almost no one uses RAID 5 in large arrays like this--but perhaps this may be because they are usually for enterprise purposes.
The array is backed up with an external JBOD system on a weekly basis, so even in the worst case scenario, failure would not necessarily be catastrophic.
Metadata and artwork is stored on the array, so random access speed is sort of important. Right now it takes a 5-7 seconds to load a screen of two dozen movie covers. I've considered upgrading to a more powerful raid card with dual core to help with this issue but they are extremely expensive.
The entire array is within the media server itself, with the RAID card plugged into the pci-express slot of a X58A motherboard with a Q6600 processor.
