New 3.4.1 install, database sizing?

Hello all,
We’re planning to start using RT 3.4.1 on MySQL and, if possible, I hope to
get some feedback on the approximate size our database will reach after one
year of use. Our old system, in limited use, was logging 150 requests per
week. I’m forecasting that RT will see wider use within our department and
may log up to 350 requests per week. I can’t offer a guess as to
attachements, our old system didn’t offer that.

Space estimates and other suggestions are welcome.

regards,
