Next DIY NAS (lemmy.ml)

Hi all,

I am looking at building my next NAS. My current will move to offsite, and the new will be primary. I previously used this motherboard, and was planning to go with that again. Then I saw this one, which seems like a better option. It has a slightly better CPU and a PCIe slot, but can only have 32GB memory max compared with 64GB max on my current.

Am I missing anything or is this a no-brainer to switch to the N100 board?

The N100 only has 9 gen 3 PCI lanes. The board has 4 USB ports (2 x 3.0), 4 2.5G ethernet ports, 2 m.2 slots and 6 SATA connections. They might be using a PCI splitter chip to connect all components, which depending on the type and how it's used could have a big effect on I/O performance.

EDIT: The N5015 from your previous board only has 8 lanes. What was your max read/write speed on it and did you see anything strange in lspci?

What is the best way to check max read/write speed? Here is the output from lspci. Do you see anything strange?

lspci looks fine, I don't see anything strange.

I usually just use dd to check write speeds.
