  High energy physics experiments are currently recording large amounts of data
and in a few years will be recording prodigious quantities of data. New methods
must be developed to handle this data and make analysis at universities
possible. We examine some techniques that exploit recent developments in
commodity hardware. We report on tests of redundant arrays of integrated drive
electronics (IDE) disk drives for use in offline high energy physics data
analysis. IDE redundant array of inexpensive disks (RAID) prices now are less
than the cost per terabyte of million-dollar tape robots! The arrays can be
scaled to sizes affordable to institutions without robots and used when fast
random access at low cost is important.
