ReadyNAS NV+ performance and file permission issues.
I have a NV+ with 4x1TB HDD. Lately its performance is pretty slow. Initially I attributed this to marginal WIFI connection to my router (the NV+ is hardwired), but the other night I connected my laptop up via ethernet cable and confirmed the performance wasn't a fluke. I got about 3.5 MB/s via rsync, which is about what I get with CIFS and NFS.
Second issue is file permissions. I noticed these were fouled up when I was using Free File Sync (FFS) to sync up my backup disk to the NAS (I would like to this via USB, but my backup disk is 5TB, so it can't use USB backup on the NV+) and saw that all transfers from the computer to the NV+ were failing. Transfers in the other direction are fine. I have switched several times between user and share over the years, so I'm guessing somehow that got hosed up.
At this point, I would kinda like to nuke and pave the NV+, but what do you guys recommend? If I do that, will a factory reset do what I need?
The fastest method over wired ethernet,using NFS, followed by Windows (CIFS). Rsync is robust, but not as fast as the other two for full restores.
One popular method is to configure the backup as incremental NFS, then edit the job after it completes to use rsync. Then rerun it. Running it again should be incremental (and very fast), and it can clean up any mismatches in owner/group/permissions/timestamps.
If you are connecting the USB drive directly to the NAS, then local->local is the fastest option. But that is slower than wired ethernet on the NV+ v1.

What firmware are you running? Do you have SSH enabled?
Also, have you checked the disk smart stats?
You can of course back up the data and try a factory reset.
- SMART attributes look ok. SSH root access is enabled. I installed it and poked around but i didnt change anything with it. firmware: RAIDiator 4.1.14 [1.00a043] Factory reset keeps my current firmware version or reverts to original?
When you update the firmware it is both updated on the flash and on the disks.
So when you do a factory reset it will wipe all data, settings, everything and install the firmware currently on the flash. 4.1.14 would be on the flash on your system at the moment so that is what it would install.
Your system would be returned to the state it would've been in if it shipped from the factory with 4.1.14.

How does SSH affect performance?
I cobbled together a backup drive last night. Apparently just having a <2TB partition on a larger drive isn't good enough to get the NV+ to recognize it as USB drive with a valid partition. Hopefully this will give me enough redundancy to feel safe nuking the NV+ with a factory reset.
Also, I believe I saw in another post that Share permissions were "deprecated". Should I stick to user permissions after the FR? What are best practices to keep all of my files readable and writeable. I don't really need multiple users, but I can create one user to log in to shares with.
Would the shares be owned by admin, with RW rights given to the user? Is it possible to make shares that are owned by the user? I'm definitely going to avoid "guest" being turned on, since his "nouser, nogroup" files are not RW by the regular users. I really don't want to screw this up.
I have read this post, but it was a bit confusing. It seems to me that the extra layer of abstraction that the NAS adds above the standard linux permission really makes for some big headaches. The post I linked seemed to imply the best practice was owner: admin, group:users, set group and everyone to RW and then adjust the protocol permission as necessary?
