Apparently it's tied to the GUID of the USB key. You can extend it twice for 14 days each after the 30 days. Only thing I can think of is that I used this USB key to trial it once before. I know I did just tinker with it out of curiosity early this year for a few days, so that must be the case.

Thanks. I'm aware of this but I never got the 30 days to begin with. How does the trial validate the time? Is it tied to a specific piece of hardware?

I went to run UnRAID 30 day trial, but realized that it only is showing me 14 days. So is it 14 or 30 days? Thanks.

Thanks.

Thanks. That's the thing. The PC transfer speed is showing about 60MB/sec, roughly equal to the parity write speed. Maybe just coincidence, not sure. But single UnRAID data disk write speed is about half of PC write speed. Either way, not a big deal. Just curious what was going on.

Ah, so it caches to RAM by default then? I have 8GB RAM, and Dashboard showing consistently 42% used. Tunable (md_write_method) is set to "Auto"

YES

Thanks. But I'm writing only one file at a time, sequentially. EDIT: And transfer speed says ~ 60-70MB/sec but no single data disk ever hits that performance, only the parity disk.

I'm just using the trial at the moment to toy around with UnRAID to understand how it works. I have four 2TB disks set up as 3 data disks and one parity disk. I set it up with "most-free" allocation method on my test share. It's set up on 1GbE. I started to transfer a few hundred 1GB files to check transfer speed. It runs at only about 60-70 MB/sec. When I look at the transfer speeds I see this: The transfer speed from the host PC over SMB shows 60-70MB/sec. But I consistently see writes across all three data disks similar to what' sin this image. Shouldn't it only write one at a time? I didn't think UnRAID split files up, but distributed individual ones across the disks? I understand Parity would require reading from all disks, but not writing. Can someone please help me understand how this works? Thanks.
