unRAID is simpler and easier to manage than TrueNAS but requires a license:
- Basic (6 disks) = 53,10$
- Plus (12 disks) = 80,10$
- Pro (unlimited disks) = 116,10$
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
unRAID is simpler and easier to manage than TrueNAS but requires a license:
unraid also lets you add drives of varying sizes to the array (as long as it's as big, or smaller, than the parity drive(s)). ZFS stuff doesn't really let you do that.
I have no experience with TrueNAS, but I have been running unRAID for more than a decade and I really like it. During that time I've upgraded my hardware twice and unRAID required zero reconfiguration.
It "just works", and there are a million and one docker applications available on the "app store" that are extremely simple to install and use.
I use Unraid because everything I want is built in. I also save a lot of power and hard drive wear. Due to the array architecture, all of the HDDs are spun down most of the time. Out of the box Wireguard and automatic remote flash backup are a blessing. Had a major headache from all the NAS OS I've tested over the years and have never regretted purchasing a license. Besides minor problems with macvlan I had zero issues with Unraid within 3 years of usage.
Your HDD will be fine for Unraid just keep in mind that your biggest disk should also be your parrity drive. I also started with an 256GB NVME cache and it helps a lot since no HDD must be running during idle. My Jdownloader download cache, Docker images and appdate remain permanently on the cache drive and I have a plugin to back up its content to the array.
FWIW, I'd just stick to TrueNAS. I don't think you'll find an advantage by moving over from their Scale product.
