SQL Server 2008 standard is more than capable of those insertion rates PROVIDED you have hardware capable of supporting it.
The question you really need to be asking is do I require the ability to search the captured data quickly?
This SO answer might be of interest: What does database query and insert speed depend on?
The number (and width) of indexes on a table will obviously have an impact on insertion rate.
If you are considering open-source, then MySQL is often cited as being able to handle high volumes.
