Some info from their website: DATAllegro v3 performs table scans between 0.5TB/minute and 10.5TB/minute. DATAllegro v3 offers new capabilities to handle complex workloads that are a mixture of near real-time loads, long analytical queries and short quick-hit queries. Improved workload management gives queries with low workloads higher priority, reducing the overall workload on the server. DATAllegro also provides a comprehensive architecture with a high-speed loader performing loads at rate of over 1TB/hour. The loading server or landing zone within the high-speed appliance network is used to provide a loading services with a minimal impact to queries being run.
