title: Does creating a tablespace on an NVMe disk improve performance?
body: <p>Does creating a tablespace on an NVMe disk improve performance?</p>
  <p>I currently have PostgreSQL installed on an SSD disk and I bought an NVMe disk to improve query and process performance. I created a tablespace on the NVMe disk and then created a database using that tablespace.</p>
  <p>My question is whether this will really help make queries faster. The SSD has a speed of 500M / s vs 3000M / s that the NVMe has. I made some queries with the database using the default tablespace on SSD vs database with tablespace on NVMe and there is not much difference.</p>
  <p>Is it necessary to install the PostgreSQL on the NVMe disk or is it not necessary?</p>
