Thanks to @andrew_cb and others for bringing awareness to this. I had no idea my 6100 has limitations due to the eMMC. I went out of my way to buy a 6100 over my own router build because I just wanted to setup my router and forget about it. As someone who is fully remote the router is the last thing I can have fail.
I saw the threads on Reddit and did a quick check. Just over 1.5 years of having my 6100, it’s already at 70% wear.
I bought 2x16GB Intel Optane Drives which you can get for less than 5 euro a piece and managed to get them installed and set up in a mirror for redundancy (the drives are so cheap, I think it’s silly not too). I also 0’d out my eMMC drive to ensure it does’t cause any conflicts.
I’m not thrilled that I had to do this, I’m thankful there were M.2 ports on the 6100 that I could use. But my biggest take-away is that installing your own SSD is not “supported” and could void your warranty is unacceptable. I think there should be a well documented SSD upgrade for any device that has an available slot, it should not void the warranty, and most definitely shouldn’t be discouraged.
As a side note, I really wish the installer was offline. I was sweating bullets attempting to configure the WAN in the Installer with PPoE and VLAN tagging (don’t get me wrong, it was easy, but if it didn’t work I’d be SOL).
