I would be extremely cautious about using any consumer grade TLC or quad-level-cell SSD in a "NAS" for serious purposes because of well known write lifespan issues.

There's a reason that a big difference in price exists between a quad-level-cell 2TB SSD and an expensive enterprise grade one with a much higher TB-write-before-dead rating.

This might look cool but check back in a few years and see how much of the drives' cumulative write lifespan is worn out.

I also cannot even imagine spending $4000+ on a home file server/NAS with copper only 10GbE NIC and it not having at least one 10G SFP+ interface network card.

Okay, so he wants it to be tiny? But in a home environment the major problem is more power consumption and noise, so you can often go with a well ventilated 4U height rackmount case for full size ATX motherboard, which is roughly the size of a midtower PC case turned on its side.

This lets you use motherboards that will have enough PCI-E 3.0 x8 slots for at least one dual-port Intel SFP+ 10G NIC which are very, very cheap on ebay these days.
