XRAID-2 vs SFH-2 any real difference in space/performance & dual NAS Backup question
I wanted to know is there any real difference between Netgear XRAID2 (RAID6) and Synology SFH2 (RAID6) in terms of usable Hard drive space or performance on 4x10TB 4x8TB 4x 4TB (61.7 Tib XRAID2/RAID6) on say an RR4312X vs a similar 12 bay model 10G model from Synology..
we were able to aquire a brand new RR4312X from an authorized Netgear reseller for basically the price of an RN528X due to a large order cancellation from one of thier clients..... we are using that as a primary NAS XRAID2/RAID6 and we need a 2nd 12 Bay NAS as a backup (we have many smaller size HD's 2TB to 8TB HD -vs- going with a 6 or 8 bay NAS and forced to buy more expensive 10TB to 14TB drives to get to 60TB+) Buying another RR4312X is out of our budget - we looked at the R2312X but it's 934mm in depth way too big for our rack (the RR412X is only 707mm)
So we are thinking about buying a "lower cost" 12 bay NAS with optional 10G like (RS2418+ /RC18015xs+ RS2617RPxs/RS3617xs+) from Synology but I have never used Synology or know much about SFH-2 and wanted some feedback.. on replicating from one NAS to Another or interop issues with ReadyNAS - we are also wondering if it's worthwhile to buy an older RR3200 or RR3220 model & install OS6 or if thier are "known issues" with these models.. The primary function of this 2nd NAS is an offsite backup to the first and if their are any loud Fan issues with the older RR3220 Models.. let me know your thoughts.. thanks

I don't know much about Synology, but I am not seeing SFH2 on their web site. Did you mean SHR-2? If so, it looks pretty similar, and likely both use mdadm underneath.
Overall, you'd lose the option of using ReadyDR to back up your NAS if you go with Synology. So you wouldn't be able to back up snapshots, and backing up iSCSI Luns would be much less efficient.
The ReadyNAS hardware warranty isn't transferable, so it doesn't cover used equipment. Also, Netgear doesn't support used NAS (and wouldn't support an OS-6 conversion either). So you'd lose support if you go with a used product. The RN3220 is an OS-6 NAS, so no conversion would be needed. The older RN3200 is OS-4.2.x. If you go with that, make sure you get a v2, as the v1 has a 2 TB drive limit in slots 5-12.

Here is the link for your convenience. Researching there might also give you a good idea to what extend the forum might be helpful should you later run into issues and will seek for assistance from that user community.
