  • Use sg_format to run a low level format on the disk. 512E vs 4kN isn’t going to change much in a homelab environment. If you create a filesystem with 4k clusters, Linux will send 4k wrudte blocks to the disk. The firmware on the disk will write that out into 8 logical disk sectors, usually in a single 4k physical sector. I use my storage mainly for media and there’s no performance difference between my 512E disks and my 4nN disks. I simply don’t have an intense and sensitive enough environment to show the performance gain. I’d say leave the low level formating alone and just write a filesystem on top of it with 4k blocks.















  • The exception here would be ESP32 devices. These have been some of the most reliable devices in my home and the most versatile, no Internet access required. Zigbee works well, but runs in the same frequency space as wifi and Bluetooth. Matter and thread are the new hotness and run in that space too. They all work well together, but something to consider. Z Wave is in a separate frequency space, but is a less open protocol. I have at least a few of all of these and they all play nice. Consider your priorities and choose what’s best for your application.
