The Free Electron Laser in Hamburg (FLASH) at DESY is a user facility for the photon science community. It produces laser light of short wavelengths from the extreme ultraviolet down to soft X-rays. To study, monitor and document the machine performance and parameters and also to collect the results of the experiment measurements, a fast data acquisition (DAQ) system has been developed. Having above 1000 linear accelerator diagnostics channels collected by the DAQ currently results in a data rate of ~100MB/s. The large amount of data requires corresponding data storage and management to enable an efficient data retrieval. This paper will focus on the data paths, storage and bookkeeping. A number of tools provided for the users to work with DAQ data will be described. The current status of the achieved performance in the data storage and retrieval will be covered as well.
