300MB of memory is good enough?

Hi there Pro's,
I just signed up for a Dreamhost vps trial account for the minimum pack which offer 300MB RAM and unlimited TerraByte of traffic for $15/month.
They also offer extremely cheap SSL certificate for the account ($15). I am not really sure what to think of it cause other hosts offer maximum a pro or business shared hosting in this price range. I am thinking maybe the 300MB RAM is too law but I have no clue since just had shared accounts before. Will I face errors and other problems…
