I believe when you create an ext2 filesystem you can select the block size to be 1k, 2k or, 4k. Also maybe look into ReiserFS which I seem to recall will pack multiple small files into the same block to save space.

Also of note is if you are using ext2 (common in Linux) or FFS (OpenBSD) and probably others you have to be concerned with the inode count ("Index NODE"). Every file on those systems needs an index node. If you have too many files you won't be able to create any more even though you have free disk space. Use the command "df -i" to see how many inode your partitions have free. I've seen it happen more than once and when you run out of inodes and try to create a file you will get a "No space left on device" error message.

Also note that ReiserFS does not use inodes. Instead it uses a balanced tree. Balanced trees are faster to search when you a large number of entries than a linear list (which I believe ext2 uses for filenames in a directory).

All that said I don't really understand how your data will be generated and accessed so I'd also probably default to suggesting a database like others above have said. That's just because it's eaiser to let some already developed and tested code do the work for me. I guess what I mean sure I can write linked lists in C with pointers but Perl can cut down my development time because lists are a given part of the language.

PS: I don't want to start a language war. I don't want to talk about STL. I was just mentioning that using existing tools can help me finish my work faster.

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
