I'm talking about a system which puts many many 1MB files, spreaded over quite a deep directory hierarchy - so directories don't have a huge number of files. It's a proprietary software (yes yes too bad =) ) written in the company I work for (videocells.com), the product does heavy writing-new-files (in parallel) and deleting-old-files, mostly. I guess it's not really random access but not really sequential access either. Quite a tough question to answer in theory, no? I'd better do benchmarks when we get the hardware..
