Thoughts on the Aoostar WTR Max for TrueNAS?

Mine arrived in top condition. The quality of the device is top level. Temperatures are low. Only the LED screen must be configured…TrueNAS installation went smoothly

I edit in Lightroom/Premier over 25gbps network.

PCIe 4.0 x2 is 32Gbps…

What was the pricing of the 2x48 GB ECC DDR5 SO-DIMM ram when purchased via Aoostar? They don’t have the SKU in inventory, so you can’t see the price

I have a really hard time finding shops with it in Norway…

Answering myself, Aoostar takes 530 USD for 2x48 Apacer ECC

I’ve also seen that the Kingston KSM56T46BD8KM is available in 32 or 48 GB

There’s also KSM52T42BD8KM available in 32 GB clocked slightly lower at 5200 MT/s (not sure if that’ll work?)

Question: The system should work just fine with one SO-DIMM, just slightly slower?

Yes. There used to be a rule of thumb that doubling the RAM speed boosts overall performance by 15%.
Not sure whether it is applicable to this case, especially if we take into account that most of the RAM would probably be consumed by ARC.

The main benefit would come from using two memrory channels rather than one.

Quick googling shows 38.4GB/s bandwidth for a single DDR5-4800 module. This is 300+ Gbps. So unless we are using a 400GbE network, a single DDR5 module should be enough for a typical (True)NAS scenario (assuming most of the RAM is ARC).

Well, these are just calculations/suggestions off the top of my head. I can be totally wrong.
