Huh. New 428 cheaper than increasing 316 storage
I just had an odd epiphany that I thought I'd pass along. I've got a RN31600 home theater movie/music server with 6 6TB drives configured as XRAID6. I've passed 80% storage usage and loading today's ...

one thing you might consider, if you haven't already, is moving to dual redundancy.
The more disks you have in an array and the bigger it is, the longer it takes to rebuild/resize, the greater the chance that multiple disks could fail during a rebuild.
Of course you do loose a 2nd disk worth of space to parity, but greater peace of mind and better protection of dual redundancy is worth it.
In any case, never forget that no raid or device is ever a replacement for backups.
backups = multiple copies of your data, on different devices and ideally in different locations.
If there is no separate copy somewhere, then your data is not safe.

Yes, I completely agree. I've been using dual redundency for for about 5 years now. I got concerned when I reached 6x4TB, and with 10+TB drives out now, its even more critical.
As for just one copy of anything, I'll go you even one more. I learned the hard way once that "A single *unverified* copy of anything is not a backup". I had some critical data once on a disk that failed, and then I discovered my only backup was invalid. The copy had been made, but didn't include all the critical data. Cost me a month and a half's worth of work. Since then I've always tried to make sure I'm backing up everything I think I am, and then verify that its fully retrievable. I also archive backups once or twice a year, just for peace of mind.
It's odd. I've been in this silly business for over 50 years now and I tell people that the longer I'm in it, the more paranoid I get ... and the more time that saves me. ;->
