PROBLEM TO BE SOLVED: To suppress a decrease in write performance due to conflict between a write access and a read access.SOLUTION: A storage device 1 acquires a data block DB which includes event data, time series information t, first attribute information p1, and second attribute information p2. The acquired data block DB is temporarily accumulated by a first temporary accumulation part 2 to a first temporary storage part 3 and is temporarily accumulated by a second temporary accumulation part 4 to a second temporary storage part 5. A first storage part 6 stores a plurality of data blocks DB accumulated by the first temporary storage part 3 to a first storage section 7 by rearranging them in a time series order identified by the time series information t every first attribute information p1. A second storage part 8 stores the plurality of data blocks DB accumulated by the second temporary storage part 5 to a second storage section 9 by rearranging them in a time series order identified by the time series information t every second attribute information p2. |
