We ran a 1.5 hour test this morning of the DAQ system. All crates except for Tagger and PS were used (44 crates) . Crates were controlled by the Trigger Supervisor. Other conditions:

Trigger: ~30kHz random (internal to TS)
Accepted Triggers: over 20kHz and fairly stable.
Rate writing to RAID disk: 450MB/s (reported by CODA)
Rate reading from RAID (for copy to tape): ~400MB/s (via Paul L. measurement)
Total Events: > 100M (only ~30k unique events in M.C. sample)

The file transfer to tape started automatically and seemed to work. Stub files are
written to the directory below. There may be some structural issues that with the
files due to recent changes that prevent the current version of the DAQ plugin from
reading them correctly.
