ReadyNas 628X new setup with 10TB drives
I just purchased a diskless version of the RN628X and purchased 8 10TB WD Gold drives. I have populated the entire unit and with 10TB drives looks like it will be maxxed out. Since this is a totall...
I would stick with XRaid 6 with 2 disc failure. With 10TB drives, that's a whole lot of data to lose if anything major goes wrong. While it'll take a while to rebuild 1 10TB HDD back into your system, which puts extra stress on all your other HDD's rebuilding the system. In fact if you don't NEED all that space at once. Say you only need around 10TB or so to start out. Maybe stick with just popping in 3 HDD's for XRaid5. As your system grows you can pop in another HDD and as it grows some more pop in another and so on. This way you have less wear and tear on your HDD's. You can spread that out. That's a nice thing about using XRaid. You don't need to pop in all the HDD's at once to use them. Maybe you need 6 of them to start. I have no idea why you need so much storage.
The other thing, a NAS is not a backup solution. Not unless you have 2 of them and one is backing up to the other. Backed up to a off site location is even better. All kinds of things could happen. You could be robbed. You could have a fire. You could have a major NAS crash. Who knows. With 10 10TB HDD's in Xraid6, that's about 55TB of Data you could lose at once if full. Generally when you have that much to backup, you really need a second NAS, with just as much storage space. I'm sure you spent a bundle already.

If a 40 TB volume is big enough, he could also consider RAID-60 and 4 RAID-1 volumes.
RAID-60 actually offers the highest protection against routine disk failures - protecting against two-four failures, depending on where they occur. With 8 disks, the overhead is similar to RAID-10 (40 TB volume).
Multiple RAID-1 volumes has the fastest resync, and is the easiest for data recovery (since only one disk is needed to recover the data on that volume).
Those are some good points.
Thanks for those good points and information. I needed to deploy the unit so I reset it back to default and kept the original Raid 6. The original data is stored on a small emc san and have about 10TB of data in use. As the data is moved around/worked with it resides in different folders at different times and the Readynas gets daily copies so it gets multiple versions of the same files needing a larger capacity than the 15TB san. This does serve as a 2nd copy backup with the caveat of it being onsite with the original data. We are looking into whether or not we could do secure internet (off-site) backup with about 10TB of data as some systems offer a seed drive option now. Thanks again for the great information.
You can get a NAS for another location and use rsync, or maybe better as you're going over the Internet, rsync with SSH. I just got a second NAS to handle Backups as doing it manually was just to much of a Hassle with 13TB of Data. But after it's all copied, Which mine is busy with right now as I just got it setup last night, I could bring it someplace else and let it continue to do it's thing. Since all the Data will be on it, now it's just whatever is new, so it wouldn't have to transfer much over the internet daily after that. So my ReadyNAS 516 is copying files to my QNAP TS-431. It's a cheap 4 bay ARM NAS, and I'm using 2 8TB Seagate Archive HDD's in it as those are pretty cheap in a RAID 0 setup, which is no redundancy. Don't need it as it's a Backup!!! That takes care of the 6 3TB HDD's in my 516 in RAID 5.
Every24 hours my 516 will backup to that QNAP. Took me a little bit to figure it out and get it working. The QNAP interface is a lot differnt from the ReadyNAS. Though you could get a low cost ARM ReadyNAS also. After all, it's just backup. So you may want to look into something like that.

It depends on the business impact of a NAS failure.
If the impact is high, then getting a second NAS on site would be a good precaution. I'd use rsync backup (as opposed to ReadyDR), because that makes it easy to cut over to the backup NAS if the primary NAS fails. I'd also keep SMB, AFP, and NFS off on the backup (turning them on if you need to cut over). That gives you a bit more protection from ransomware infecting the PCs.
You could get an RN528x perhaps, but if you need to run the business using the backup NAS, you probably don't want to go lower than that.
Cloud/Offsite backup is important too - adding disaster recovery.
