Hybrid Ceph Storage: SSD WAL/DB Acceleration with USB Drive Data
Running Ceph on USB drives sounds crazy until you put the WAL and DB on an SSD. Here's how separating metadata onto a Crucial MX500 transformed my 15-OSD homelab cluster from sluggish to surprisingly capable — at a fraction of all-SSD costs.

Adding another SSD Drive
In my eternal tinkering with my Lenovo Thinkpad T480s, I have continued the trend of adding new features. So earlier, in A new to me but old laptop and New Laptop update, I threw out a bunch of enhancement options. Some of those I’ve done and some I left on the backlog as things that just cost too much on my metric of usefulness per dollar. The WWAN SSD for extra storage was one of those that just seemed like a bad bang-for-the-buck for storage. I also like the option to add a SIM card and have cellular network available in case I have to go back to consulting on the road.
