i generally will not permit a file to exceed 2 gig for reasons of managability.

eg since a file is the smallest recovery unit, i want something small enough so that i can easily recover it without incurring too much downtime.

if i need to move some files around, 2 gig is small enough so that i can do it in parallel if need be

it may be difficult to find space for a very large file in the event that you need to clone it for some reason.

thanks,

steve

the ever popular answer "it depends"

how large are the tables you are storing in these datafiles? Is this a data warehouse where you will be storing massive amounts of data? (1000 2GB datafiles to store one table's worth of data is somewhat obscene)

Is it a large database? Heavily used? OLTP?

I'm not making fun, it's just that a blanket statement "what are the pros and cons" just doesn't make sense
