Bonding 10Gbe ports to get double bandwidth with RN626X - is it possible?
I'm looking to set up a second 626X for our San Francisco studio and am curious if I can take advantage of bonding to double up and downstream bandwidth on a 10Gbe network. The idea is to run the 626 into this switch:
MikroTik 5-Port Desktop Switch, 1 Gigabit Ethernet Port, 4 SFP+ 10Gbps Ports (CRS305-1G-4S+IN)
which my desktop machine would connect to via a 10Gbe card.
I've tested the 626 10Gbe port direct into my system and got ~450-700Mb/s up and down with a Cat 6 direct connection to the NAS which is configured in XRAID-6 with five 8TB Segate drives.
Would it be possible to get double that bandwidth using bonding and perhaps better quality cabling? This would be the same ReadyNAS model also in XRAID-6 but probably with larger drives. I'm thinking four 12TB WD Ultrastars.
Any advice much apreciated. Thanks!

I don't think so. A 10 gpbs interface can carry over 1200 MB/s of traffic. You didn't get anywhere close to that in your testing, so you weren't limited by the network. FWIW, I also use 10 gpbs with my own NAS, and I get similar speeds.
Even if you were network-bound, you usually only see a benefit if you have several devices accessing the NAS at the same time. Bonding works best when the bonded interfaces are carrying several different data flows (going to or from several different devices)..
It does no harm to try it though - your switch does support bonding.
Makes sense. I was hoping I might approach NVMe speeds but that's probably a pipe dream. Even if I could get SSD speeds with NAS capacity and redundancy, that would be a win. I've been wanting to do this upgrade for a while and will hopefully have the needed resources soon. Once I do I'll give bonding a try and let you know how it goes. Thanks!

ReadyTier is worth considering. You'd need to go with no more than 6 mechanical disks though.
Caching metadata on the SSD would speed up folder browsing, and copying folders with small files (photos for instance). Caching data is also possible, and could help if you frequently access a working set of files while on a project.
I have my 626X (4 X 8TB RED PRO) set up as you describe (bonded to a M4300 switch 802.3ad LACP Layer 3+4) and can confirm an increase in bandwidth/throughput. For what it is worth, all connections are with CAT 6A cabling. Of course, your other devices' capabilities will determine how much of an improvement you actually see.
