Just to make something clear:

if the type is always the sam SQL Server 2000 can handle 2100

And to be honest, if you need more than that there are probably bigger issues with you design 😉

if it is all abou list processing then csv are way nicer (in my opinion)

The only case I have used something like this is when multiple (master/detail) records needed to be transfered in on go. But for reporting I think this is not the case.
