You'll want a server with LOTS of hard drives spinning under it. Fast
RAID controller with battery backed RAM. Inserting the data is no
problem. 300kb a minute is nothing. My stats machine that handles
about 2.5M rows a day during the week is inserting in the megabytes
per second (it's also the search database so there's the indexer wtih
16 threads hitting it). The stats part of the load is miniscule until
you start retrieving large chunks of data, then it's mostly sequential
reads in the 100+Megs a second.
The more drives and the better the RAID controller you throw at the
problem the better performance you'll get. For the price of one
oracle license for one core, you can build a damned find pgsql server
or pair of servers.
