Disadvantages of having many Indexes in a SQL database?

I am a database newbie and I am working on the design of my database. For efficient operation of my application I need indexes on half of my columns since with that my look will be logarithmic time.

But is there any disadvantage of having multiple indexes in a same table?

  • insert/update performance when indexed columns are modified will be worse
  • more indexes will use more disk space
