I'm hoping the community can help me out with some advice or experience prior to me making hardware investments.
1. I've Run Freenas Ver8 for about 8 Years from a USB Stick BUT I've heard mixed news on this being a bad idea on OMV, is there any basis to the negative things I've heard or should I be okay as long as I make a backup to a spare USB from time to time?
2. As Freenas has aged I've heard it gets memory hungry the more storage you add, I want to understand if I can expect a similar issue with OMV? I'm running a low spec HP Microserver Gen6 with a AMD Turion™ II Neo N40L 1.5ghz Dual Core with 8Gb's of RAM and I want some idea if I'd be asking too much of it to run two or three RAID configs 2x2tb RAID1, 2x8TB RAID1 and 4x 2.5" 2TB Drives in the 5.25 Bay with a conversion kit on RAID 5 Total Approx 16TB Storage all Redundant. - I'm currently testing with 3x2tb's in a RAID5 and the LOAD was averaged at 2.20 (25% to 50% CPU) whilst re-syncing the RAID which worried me but after that was done it settled to 0.09! and has happily served up music and shares without issue the entire time.
3. I'm considering making one of the RAID volumes (2x2TB RAID1) LUKS encrypted and served up as a share, Encryption always seems to hit hard, I've tried various solutions with Freenas including Encfs, Ecrypt2f, and client side Veracrypt. Sadly they all hammered the transfer with a 2gb file going into the hour+ range. Does anyone have experience with the LUKS volumes over SMB on OMV and comparisons to standard unencrypted traffic? My base network isn't superfast as i'm using powerline adapters but I'd still like to see 100MB/s!
Apologies for the random questions but I'm hoping to finish testing and build the final solution soon, my FreeNAS box is on it's way out, it's failing fast.
If money was no issue I'd just fill the box with 8TB NAS drives and test from there but realistically I only have budget for two new NAS drives and I have a few 2.5" drives hanging around so an additional Sata controller and 4bay 5.24 conversion kit is the most cost effective option.
