摘要：This paper discusses an implemenation of a high data-rate recording system for VLBI and e-
VLBI applications. Using commercially available components, a low-cost system has been built
and tested to fulfill the EXPReS project requirements. The results described in the paper successfully
demonstrate a recording prototype which can handle sustained data rates beyond the goal
of 4 Gigabits per second. Furthermore, data can be losslessly streamed over the Internet to its
final destination at the correlator center. The improvement of the system is tightly dependent on
advances in hardware components that would make achieving a throughput of 8 Gbps feasible in
the next couple of years.
