Making a pool that can saturate 1000BASE-T?

[oguruma]

Suppose you wanted to make a pool out of spinning 3.5" disks of a total of 24TB usable storage, and have that storage be able to reliably write and download at 1Gbps, even with a total of 24TB of data on the pool (obviously, this would mean that the pool has greater than 24TB of usable storage).

What would be the most economical way to do that, assuming using TrueNAS approved drives? I'm not really planning on doing this, but more out of a sense of curiousity.

ZFS SLOG not speeding up writes, and recommended size for 10 GBit LAN

Having added a 128 GByte SLOG device (Samsung 830 SSD) in TrueNAS CORE and SCALE I do not see any write speed improvements during 10 GB LAN write operations. How can I make sure the the SSD is being utilised? The IO stat for sure. Is there any tuning to be done? In my understanding the SLOG...

Write speed around 400 Mbyte/s in this setup on an empty pool - 5x old HDD in raidz1.

Nothing fance, 1 Gbit LAN / wired connection should be saturated easily.

For my purposes I forgo of a SLOG device.

Slog useful for SMB traffic?????

I’m new to Truenas and I’m a bit confused as to whether i will benefit from a SLOG at all in my configuration. My understanding is that data writes to the data pool can either be synchronous (slower but provides data integrity and protection) or asynchronous (faster but without data...
