Thanks, it was an honest question. I'll look into OBR10.
Currently I'm at a small-ish startup and I have ~150 TB of data on a synology nas. It's in 2 raid groups, both raid 6. Seemed safe enough.
edit Ah, right. From some reason I didn't make the connection that raid 10 was raid 0+1, it doesn't work for us simple because of the sheer amount of data we need to store. Also, although it would be a real bitch if we lost everything(like set us back a week+), most of the data is derived data, and we have all the raw data in cold storage, so we could eventually rebuild the array from scratch.
