SAS drives tends to be top quality server stuff… I would keep them until the break then replace with cheaper sata.
Unless you need something less power hungry (SSSs?) or less noisy.
Also keep the hardware raid, why not. You should be able to remove the raid inside its bios and see the four disks individually.







Love ha.
I suggest to purchase a home assistant gren device as its really well done and super stable. I moved to one of those after hosting ha on many different devices over time, and would not go back.
You also support the project, which is cool.
