both of your vps lacks something for DB.

Its better if you get 3GB RAM an 20GB 15K HDD for Database VPS.

Hosting on RAM disk is risky. if your vps restarts for some reason, you will loose the latest db data (considering you backup database to hdd every 1or few hrs).
vgnheart Reviewed by vgnheart 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
