Database or store to handle 30 Mb/sec and 40,000 inserts/sec

We have a need for some sort of database package that can handle the following specs:

Average data rate - 30 megabits/sec.
Max # inserts - 40,000 records/sec.

What sort of database or store could handle this load? I'm looking to price out a repository, basically capturing the best bid/ask and last information from all 6 option exchanges, and then have a retrieval application query this data in a timely fashion.

suggestions (with links to benchmarks/info) are much appreciated

thanks much Received on Tue Feb 07 2006 - 09:02:05 CST
