I see no reason to have a ram disk of any kind if you are using the 3gb ram VPS for your MySQL server.

You could easily run with that server even if your site's DB grew to 5gb.

You just need to edit the configuration correctly for your server and also do a correct setup by looking into optimizations.

A ram disk for MySQL is the worst idea to ever use even a solid state drive is a very bad idea. This coming from a host is very sad.

Do not try that unless you plan to destroy your database within 5-6 months if your traffic is more then 1k daily.
JamesVaporH Reviewed by JamesVaporH on . Need helps choosing VPS for database server I have two VPS. Both are Linux VPS. The first VPS has 1GB dedicated RAM, 3GHz CPU and 20GB 15,000 rpm HDD The second one has 3GB dedicated RAM, 4GHz CPU and 25GB 5,400 rpm HDD I'd like to improve my website performance with using one VPS to store database and the other to run apache. My database is now about 800MB without compress. Which one should I choose to store mysql database? Thank you.:) Rating: 5
