I'm sure it's been asked before and I did try to search but I have a few other questions as well... I'm a TrueNAS newbie, I just built my first NAS after having a hardware raid controller fail on me in another server. So, totally newbie to ZFS and I have a few questions.
My TrueNAS server:
Supermicro SSG-6028R-E1CR16T, X10DRH-CT Motherboard
Dual Xeon E5-2640 V4, 64GB ECC RAM (4 x 16GB PC4-2400)
IBM M5110 HBA (LSI 9207-8i IT Mode)
Boot: 2x SP A55 256GB SSD
Storage: 6x WD 14TB Ultrastar DC HC530 (WUH721414ALE6L4) - RaidZ2
NIC: Dual 10Gbit LAN w/ Intel X540
This is in a home storage environment, mainly used for storage of large files (media/video for Plex) with added storage for some documents/file backups and some VM vmdk files for a VM I run from a Win 10 machine to do my downloads with SabNZB and serve as my main Plex server. I know I could use TrueNAS for Plex & SabNZB but I'm not ready for that yet.
I started with 6x WD 14TB Ultrastar DC HC530 (WUH721414ALE6L4) hard drives configured in RaidZ2. This gave me about 50.74 TB of usable space or so which is already 60% full and I still have a lot of data to move over. I still have at least another 21 TB of data to move over and that doesn’t include another 20-30 TB that I’m still trying to recover from my raid array that lost its card. So let’s say I need 70 TB or so with room to expand in the future.
Speed doesn’t seem to be an issue for the 6 disk RaidZ2 that I’ve been testing. So far I’ve been able to get 700MB/s to 1GB/s write speeds to my TrueNAS over my 10 Gbit network without really making any optimizations. Running the VM that’s stored on the TrueNAS seems speedy enough for now.
My big question is, should I add another 6x 14TB disks and stripe my existing RaidZ2 or should I start all over with a 12 disk RaidZ2? Since my network speeds are so fast, starting over isn’t a big deal. The question I have is more related to 1 vDev vs 2 vDev performance (with large 14TB disks) and also the amount of time it would take to resilver after replacing a bad disk when the vDev is pretty full. I haven’t seen too many posts about resilvering when it comes to large/full drives. I could care less about having 1 or 2 vDevs since Plex doesn’t really care and I can manage it just fine with Datasets.

Questions:
- Resilvering time with a 6 disk RaidZ2 vs 12 disk RaidZ2 using 14TB Disks and 70-80% full?
- Would adding more RAM help my resilver times or am I just limited to the disk speed?
- Swap size on large 14TB disks? Currently set at 2GB…
- System Data Set - It’s currently stored on my vDev, should it be on my boot drive?
- I’m running dual boot drives (SP A55 256GB Sata SSDs)… Is this a waste? They were cheap so I figured having a mirrored boot drive couldn’t hurt.
- Should I use a zVol for my download drive and/or media drives instead of a dataset? Would it improve performance for unzipping/unpacking large files? I think it might make things easier for when I’m moving files from a temp folder/zVol to my media folders so I can drag/drop to “move” instead of “copy” a file without holding shift in Windows.
- Are there any “must have” plug ins for TrueNAS? What is everyone else using for file backups?
