Dear Stevenz,
The starter plan is good
1GB with 15 GB bandwitdh. You will hardly reach 15GB for the first few months. With RM 5 monthly your financial burden can be lessen.
For the database, average usage is normally 2-3. So, unlimited should not be a strong point in deciding

You can always ask 1 extra MySQL with good reason for FREE (normal case).
Thank you,
