I recently purchased a Terramaster NAS U4-423. I installed some mixed size shucked drives (not recommended, I know) and the raid is syncing. In one day it synced up to about 70%, but has been at a crawl for the last 12 hours taking ~10 minutes per .01%. I have 2 questions I'm hoping fellow Data Hoarders could assist with:
Is this long sync time typical? I'm new to RAID, and I'm wondering if I should just leave it alone and be patient, or if it will actually take the 20 more days the current math suggests. For context I'm using TRAID.
Would I be better off with Unraid? I don't have an issue paying the license fee if the experience would be better. I haven't been impressed with TOS so far. If I did install Unraid, do they have an option to use mixed size discs?
I'm in a similar boat. My F4-423 will be here today and I'm probably not even going to bother with TOS. I'm going with TrueNAS instead. Unraid is also a possibility. Both are excellent, mature platforms. For most of the people most of the time, you can't go wrong either way.
TOS has had too many security issues over the last few years. Some of them are severe, like revealing the root password or automatically opening up SSH to the internet. In defense of TerraMaster, they aren't the only ones; QNAP had a backdoor for a long time as well. My problem is that if a company thinks these are good ideas, their overall security hygiene probably isn't great. I want to allow outbound internet access from my NAS so I can fetch backups of OneDrive and back itself up to B2 or S3 Glacier, so who knows what it's ingesting when it calls home for updates.
My suggestion would be to tool around with Unraid, then tool around with TrueNAS. Maybe even look at OpenMediaVault. If they meet your needs, then they're probably a better choice overall.
