  • Yeah it’s a fun ride.I run a cluster and the storage is replicated and distributed among them. 3/6 of my disks were QLC. One disk went bad super early and caused a bad latency but the other 5 disks kept performance up for the most part. Once I found out it was hardware I went with an enterprise SSD with a a 3 DWPD rating (drive wipe per day) and those beasts are so good. TLC m.2s seem to be okay too but I don’t think I’ll ever touch QLC again.




  • You can do a few things to reduce interference if the device broadcasting the signal supports it. Unifi APs support these settings. Most routers with WiFi probably do not support transmit power.

    1. Adjust transmit power to lower setting
    2. Higher the frequency, shorter the range (but that frequency may be highly used in the area), so #3 is the better option
    3. Analyze the frequency usage and picking a frequency that is least used
    4. If 2.4Ghz band isn’t necessary disable it and only use 5Ghz since it’s a higher frequency it again has a lower range.
    5. You could also faraday cage your room so the signal won’t leak out, but thats probably more work than its worth.
