OpenBSD's documentation are really a gem of the project. Here's a quick one from FAQ 14.8: "A rough guideline is the system should have at least 1M of available memory for every 1G of disk space to successfully fsck the disk. Swap can be used here, but at a very significant performance penalty, so severe that it is usually unacceptable, except in special cases." In that big arrray you're interested to build, I would be more concern about the time to fsck. Ref: http://www.openbsd.org/faq/faq14.html#LargeDrive
