Without firmware update 990 is a time bomb

Run iozone to test pool.
Small tests will reside in ARC and give you false high. 512gb is minimum, or change tunable to reduce arc size
Iperf to test network.
FYI Scale has a bug limiting ARC to half your physical ram. Apparently there is beta test for fix posted on TrueNas forum. And should be in production in 6 months-ish. This won't impact synthetic tests, but in real life you may want to have the extra cache
Free File Sync can auto run when a sd.card is inserted. But you are probably going to want to give a unique folder name for each disk not sure how to do that.
I use a robocopy script to inject photos. Simply enter the drive letter and what you want the folder called.
I all likelihood having 6 SD cards reading at once is going to be slower overall than doing 3 batches of 2. USB kind of sucks that way.
Unless you are going to put 6 dedicated USB hosts in your PC.
This chart mirrors what I have felt, that HDD size increase has slowed way down.
We had a 500 mbyte in our win 3.11 box in 94. 2004 I think I had an 80gb
If you have lots of small files, yes this is bad.
For videos the space lost will just be a rounding loss.
Would be interesting to test for music. A 100k 20mbyte files. You could lose a lot of space if using 1 mbyte+ stripes that have been recommended for a while now.
Draid mitigates a lot of the problems of very wide raidz

They never did make SSDs.
"Most of its SSDs use WD branding rather than SanDisk branding, but it's still SanDisk at its core. As part of this move, SanDisk will effectively revert to its pre-acquisition state, which means that WD's current lineup of SSDs should still exist with SanDisk branding, while WD will continue selling spinning hard drives only."
Dpi is a meaningless metadata value.
If I choose to print 1000x1000 pixel image at 10", it is 100 dpi.
If you print it at 3x3 it is 333 dpi.
PS shows an image size and dpi, but they are meaningless to quality or printing.
Cold backups
Put them somewhere if your house burns down you still have the important stuff

Samba prefers clock speeds over more threads.
Emby will do more with a cheap nvidia card with Nvenc than even a high power CPU.
HA isn't going to need anything.
So I say get whatever has highest clocks of the options.
