time to update my storage

[getho]

4k footage and my now more extensive use of cineform codec means my 7x2tb raid 5 is now no longer cutting the mustard.

Its running on an areca 1223 8i with sata drives on windows  (HGST enterprise).

I tend to do small projects but end up keeping quite a lot of media, filling up my raid. Problem is that I dip into this media quite frequently, so it needs to stay on a relatively fast drive. 

I could ditch the raid altogether, or replace the drives with say 4x6tb drives giving me room to keep adding. or I could go to raid 0, and get used to doing daily backups (I've had a bad experience with raid 10, was a waste of time when it came to data security).

I'm open to ideas, though - like an external solution with a more modern file system....?

You should not be using RAID 5 for video data.  It is not good for sequential data.  Since you have an Areca controller go with RAID 3 or 6

Yes bill, it was a multipurpose drive at first, I weighed the pros and cons of raid 5 vs 3 seeing as I also had tonnes of small files.

As I'm now doing more video when I create a new array I'll probably do raid3.

But still need to decide which drives to use and whether an external solution would make more sense...
