I secured Four 4TB Crucial M.2 SSDs during Black Friday. What's the best use for them? (alien.top)

This was a bit of an impulse buy. Not sure how to use them. I was thinking:

Austor Flashstor NAS, either the 6 or 12 bay NAS, but I already have a HDD Synology NAS, so it is not needed. More just for fun.
A Homelab server with a motherboard that has 4 m.2 slots if such a thing exists. Then I could make a K8s cluster or a proxmox server.
Find some other way to provide storage for a Homelab server that is not part of a motherboard? Like a PCIe board that holds 2 or 4 m.2 SSDs?

You'll actually get worst performance in most cases... Unless you are reading and writing large files

Why do you say that?

[–] travcunn@alien.top 1 points 11 months ago

For big files, modern SSDs have already reached the data bus limit so you really aren't going to get faster than your motherboard. For small files, you are actually going to get worst performance because the RAID setup will add latency to every I/O operation and it won't read from both SSDs at the same time, since the file is below the stripe size (128KB or 256KB, depending on the controller and settings).
