Best RAID/Storage configuration.

My current server (4 2tb drives in RAID 5) is currently full.
I just ordered 4 3tb drives to add to the server.

It is currently running on the Dell PERC 5i PCI-E SAS RAID controller.

What would you recommend in terms of configuration.
JBOD, some other type of RAID that support multiple size drives.

The server is only used for Moves/TV/Music storage and streaming; for up to 3 people at most, most of which are web based anyways. . It's doesn't need a tone of speed.

I've heard good things about Flex Raid.

What would you guys recommend.
 
I don't think your Dell PERC 5i RAID controller supports more then 2Tb's. I think the only way it will work is if you run SW RAID & JBOD all of the drives together. Or you can SW RAID5 the 4x 2TB's & 4x 3TB's separately if you want 1x drive of each for parity/redundancy.

I would buy a better RAID controller that supports 3+Tb's & continue to run RAID5 on the 2Tb's whilst making a new RAID5 array on the 3TB's. If you just want all of them combined then JBOD is your best bet BUT if one drive dies, you lose all your data.
 
Yes FlexRAID can work (once you've managed to plug the 3TB drives, maybe on the motherboard directly). Since it can use filled drives you could move your current data to some of the 3TB drives (keeping one free for FlexRAID parity), then break up the RAID5 and bunch all the drives in a FlexRAID array.
 
If you are happy with the snapshot-type of system that FlexRAID provides I can recommend it. I have been using FlexRAID for awhile and have had nothing but great experiences. It's really easy to use and extremely easy to expand upon so you won't ever run into this sort of problem in the future again.

You can just keep adding more data disks and more parity disks or replace disks with larger disks all while keeping one large storage pool and mainting the parity protection.
