It's impossible to make a recommendation based on so little information. All we know is you create a large number of pdf files, based on that tiny bit of requirements I would say mount a fast file system on a RAID array with an optical link to the source of the files.
What are your requirements?
What is this data used for?
How much of it is there?
How will it be searched?
Why would anybody search it?
If I had time, I could probably come with at least a dozen relevant questions, all of which you should have asked yourself before you even started investigating this issue.
My worst nightmare was a pointless infinite loop.
Work in progress; don't poke the curmudgeon!
