New to TrueNAS Scale. Couple Questions

I have 8 x 4 TB hard drives that I’ll be using, also with 2 x 1 TB NVMe drives to be used as cache.
4 of the hard drives are WD Black Drives and run at 7200 RPM, and this will be as a primary pool that I will use more often, and want to really keep Data from not loosing it. Like Downloads, Files, Photos, ETC.

The other drives are 2 x WD Red, 1 x WD Blue, and 1 x WD Green which all run at 5400 RPM. Which will primarily be used for videos, ebooks and stuff like music.

When I create the 2 pools, should I enable both NVMe drives as cache, or use 1 each for each pool?

I’m not a video editor, but may get into this. But I can easily transfer the file to my editing PC if needed. The WD Black Drives (primary) will be used for recording videos of gameplays for games.

Will this be a good setup?
Would like to know before I start to transfer all my files over to it.

Thanks for any help you provide.

Neither, until you have a reason to think you’ll need a cache (i.e., L2ARC) device. More RAM first if your ARC hits are low.

Awesome. Thanks!
Then I’ll probably use the 2 x NVMe for more important data and enable encryption just on those. And obviously just do it as mirror Z1(?).
Right now I have 16 GB of ram, I probably wouldn’t go more than 32 GB, since the main function of it would be recording gameplay of games I play with OBS.

If I upgrade to more ram, will this create any issues with TrueNAS or will it just function as normal, and obviously detect the new amount of ram.
And yes if I upgraded to at least 32GB, then I wouldn’t add to the current 16, but buy a whole new set. Just to make sure the ram is the same make, speed settings etc.

I was running basically a backup of my files in windows. Using a program called SyncBackSE, to copy files from one hard drive to another. But obviously windows sucks so much out of your system to basically just run it as a basic NAS. That’s why I decided to make the switch over.

I use to back up my stuff on external portable drives, but one day one of them tipped over and data was lost on that one. That’s when I decided to rip open the externals, and put it and case to keep it more protected.

Yep. TrueNAS isn’t Windows, so hardware upgrades aren’t a problem.

Don’t use any L2ARC (cache) unless you know you need it

Awesome. Thanks!

Check the specific models of your drives & make sure they are cmr NOT smr
