Those same people should also know that spinning rust can go very fast as well... My 8 and 12 drive spinning rust pools can read at 500MB/sec easily and get close to GB/sec.

But the 10Gbit network is there for the flash pool.

Yeah, but... The noise! I just can't handle spinning rust anymore for this alone even if the $/GB ratio is still so much better.

Consumer SATA SSDs are plentiful enough that I'm just going all in on flash when I revamp my server and do an 8 drive (+1 hotswap) RAID10 build or whatever. I don't need +60TB or anything and 8-9 drives is about the limit you can find on high end consumer mobos I think...

It is not required for the NAS to be in the same room where you sleep.

With a proper drives (and maybe some APM tinkering) you can make a very quiet one. Also using 2.5" drives is an option too.

Though if you can throw money at the problem than of course you can just buy a bunch of TB SSD drives.

Or say 1Gbps is too low bar. Even single rust drive can fill 1GbE in simple workload.

Put 8 high-quality HDDs in a stripe & mirror config. Thus you can read from 4 simultaneously. They each top at 260MB/s. That amounts to little over 1GB/s -- which is 10GbE.
