ASTT was designed by CalDigit's top engineers to provide the ultimate in sustained performance. This advanced technology is unique to CalDigit and cannot be found anywhere else.

With ASTT, the performance of your HDPro is always kept in check. When data is transferred, any highs (peaks) or lows (drops) are equalized by the Active Sustained Transfer Technology.

ASTT optimizes the best transfer size and timing between the RAID controller cache and the host machine. This eliminates performance drops and maximizes the sustained data rate.

ASTT also helps to maintain a continuously smooth transfer rate over the whole capacity of the RAID. This technology is ideal for video editors who need sustained playback, and can't risk dropping frames.

See the difference for yourself, see how the use of ASTT maintains consistent throughput, and other systems without ASTT have sudden drops in performance.
